The Herrscher floats as trying to intimidate the armored masterless servant. She shot lightning bulbs that formed into thunderclap as shooting the servant. It creating a dust clouds that covers him completely.

Something glowed from it the dust cloud then disappear within a slash of an invisible blade

???: You seem to not wield any noble phantasm... But I've seen your servant class, Caster!

HoT: Heh... are you joking me. A queen, the ruler of lightning and thunder is a servant

???: ...You must be a servant no human is able to wield such powers to summon these entities

HoT: I am herrscher of thunder and have you not know honkai is?

The servant shook his head

HoT: Let me expain then. The ambient honkai energy is the one that create those entities not me. Oh yeah I forgot. I am Herrscher of Thunder, the ruler of the element electro

???: So you're a magus

HoT: Are you really stupid. Mage doesn't exist. As I've said, I rule the thunders above and electrons that wonders as an atoms, The herrscher of thunder. The ones who rule element of electro and whom came to bring chaos into humanity. Now how about yours? 

Shirou: Shirou Pendragon

HoT: Interesting name

Shirou: ... If you are not a servant, then I must be sent into the wrong world however... This world has gave me the reasons to fight and to stay

HoT: You're no ordinary human

Shirou: I never was a human...

Saber charged at her. The Herrscher projected thousand thunderclap in which Saber deflect some of them yet most of it struct to his. It damage his armor. Saber then lifted the invisible air then strike it at her . Upon landing back on land, blood were then splatted as it falls to the ground

Shirou: Hurting a girl is truly a pain specially it's hesitating... We shall continue the fight if you want Ruler of Thunder

HoV: I WILL END YOU HERE!

Black clouds gathered as a huge thunder strike upon him. Sure it hurt him but he resisted the pain as the Avalon protected him

HoT: What are you?

Shirou: I've told you before, I was never a human. Let's part ways. The people needs help

HoT: They already turned to zombies

Shirou: Then find survivors. I will look forward in our next duel. After all you nothing but a mere girl. And as for my last introduction-

Shirou: -I am King Arthur Pendragon, Wielder of the Sword of Promised Victory; Excalibur. Servant Class: Saber, Kings of Knights. Shall let you live for now

HoT: King Arthur? Ruler of Britain and Wielder of Excalibur? I won't believe you, Pathetic wimp

The herrscher insulted the king

Shirou: Calling the king of knights a wimp is a grave mistake but since you have a mind of an innocent, You are under my mercy

Saber suddenly disappeared into a glowing dust particles. Saber as a king must help his people even though he's no longer a king he still needs to protect those are weak and hid them from the oppressor. 

few days passed Shirou was still wandering in the city. The city was quite large surely it was hard to find a survivor

???: Fire!

He heard a voice following a cannon shot. He rushed to the voice and saw a russian, silver haired loli and was amazed to kill the wandering beast. They were a feet higher than an average man.

Shirou: Young lady, that is an impressive weapon but... We should get proceed to the safe point or else you'll be killed

Saber said as he approach the girl. In which she prepared a charged attack and fired it at Shirou. Shirou deflected it with an Invisible blade

Shirou: Be careful with your toy, Little girl

???: Who are you?

Shirou: Shirou Pendragon, and you?

???: The Bronya's name is Bronya Zaychick

Shirou: What a unique form of forming a conversation

Bronya: The Bronya had a surgery due to her broken legs. The Bronya cannot perform sentences like regular people

Shirou: I see. I feel sorry for you

Bronya: Don't be, The Bronya shall go now

Shirou: Young lady, I need you safe

Bronya: I only need project bunny

Shirou: If that's how your rules are... How about I accompany you on your journey... Let's find the exit of this City of a labyrinth

Bronya: That seems to be a good idea. Da, The Bronya allows you to accompany with her

Shirou: Thank you

Shirou rushed to her side and as they walk aimlessly to in the city. While walking Bronya noticed his medieval style armor and wondering why he's wearing it, it made sound and after calculating it, the armor was for no normal human but a specific one like him

Bronya: Can the Bronya ask, Subject Shirou?

Shirou: Yeah, sure

Bronya: Why are you wearing such armor

Shirou: Ahh this... This is part of my noble phantasm. It is slightly damaged but don't worry, Soon I gather enough energy to convert into mana, I'll be able to repair this

Bronya: Are you... a knight?

Shirou: Funny that you ask... Actually king of knights

Bronya tilt her head

Bronya: The Bronya doesn't understand please explain, Subject Shirou

Shirou: We might not see each other once we part ways. I shall explain what I am. 

While Bronya floating as Saber walking she was prepared to listen to what he's going to say

Shirou: I am Arthur Pendragon, from my surname alone. I'm half human and a half dragon. I posses a magic or energy core which stores all my mana. I was as well born in Britain and became its true leader in legends. I possess my signature weapon; Excalibur, that is my noble phantasm. But I won't let you see that yet. With these armor no ordinary weapons can penetrate except other noble phantasms. I am also the King of Knights. Can tell you that as no servants in this word exist

Bronya: The Bronya understand now... It's incredible that you have such powers. The Bronya must say... she wants to observe you more. Can Bronya spend more time with you?

Shirou: Sure... Also I haven't explained it all yet

Bronya: We will talk that later
_____________________

It's night time, They were in clean part of nagazora, specifically the mountains yet honkai beasts still roams around. They were near a river, Bronya materialize a military grade food in which she put clean and filtered water in it. Saber look at the bag in which Bronya notices

Bronya: The Bronya has more

Even though it's just a few left

Shirou: It's okay. I can survive hunger more than 3 day-

His speech was interrupted by a growl from his stomach

Shirou: N-No... I... I'm not hungry at all

Saber blushed from embarrassment in which the Bronya grin

Bronya: The Bronya shall share food with you. Just wait, Bronya will boil more water for the other food

Saber lays his head on his knees and arms from embarrassment. At the end they all eat the food before sleeping.
___________________

The Next Day

Bronya look at Saber he was wearing a long black turtle neck and jeans with shoes. He wasn't wearing his armor anymore. She then ignore him after taking notes about him, she leave him be as he slept so peacefully. As Bronya look for more food from her quantum inventory but there wasn't much of it. She waited for Saber to wake up as she prepared a river water to boil

Saber slowly wakes up

Bronya: Subject Shirou

Saber sat up

Shirou: Call me Saber from now on. But yes?

Bronya: A-Ahem Subject Saber, I need to advice you to prepare. We'll be scavenging foods on the city

Saber nodded. Well he needs food too so he'll be helping her.

Shirou: Let's get ready then

Bronya: Let's take breakfast for now

Shirou: Understood

Timeskip

After breakfast. Saber materialize his armor. Bronya was amazed but she then leave him be as she took notes about the cool things about him, digitally. 

Finally came back into city, crowded with buildings. They arrived at a convenient store. It wasn't damage much meaning there could be no survivor taking it

???: Mei-senpai! We got a new one!

???2: That's good!

The voice, Shirou recognizes it

Bronya: It's now taken by other survivors. Let's get out before we could make any confliction

Shirou: Wait, I know someone

Bronya: The Bronya understood. Let's visit them. 

They both entered the convenient store

Shirou: Ruler of Thunder! Are you here?!

???: Who's there?

Shirou: I'm here to look for the Herrscher of Thunder, is she here?

???2: I'll go Kiana-chan

???: No! I'll I go, I need to keep you safe!

A white haired girl appeared with her guns pointing a Saber.

???: Who do you think you are

Bronya: The Bronya knew it... This was a fail. Project Bunny 19c prepare charge attack

Saber touch Project Bunny's cannon as it disable charge attack

Shirou: May I ask you name, Good lady?

Shirou approach the girl

???: So what? You're gonna flirt with me?! I'd rather die than you do so!

Shirou: I have no interest in immature ladies

???: Hey!! Okay you know what

??? was about to pull the trigger

???2: Kiana-chan please don't kill him!

The purple haired girl came out

???: Mei-senpai!

Shirou: We've met again, Ruler of Thunder

Mei: What do you want?

Shirou: Isn't it the duel when we meet each other?

Mei: Since when?

Shirou: ... How come have you not know? That was few hours after the eruption

Mei: Oh... I...

Shirou: I understood... I was right to give mercy after all. Ladies, can we join parties, then shall we accompany each other. This way we'll be able to find our escape off this labyrinth place

Kiana: Mei-senpai. Don't listen to him!

Mei: It's for our survival, Kiana-chan. Please join us

Shirou look at Bronya

Bronya: If Subject Saber said so

Shirou: I am greatly honored to accompany someone who doesn't wield noble phantasm... You must know gr

Shirou: You... don't know?

Mei nodded

Shirou: Oh... so you just manifest electro just like that

She nodded

Shirou: I'm more than honored... anyways. Saber... Arthur "Shirou" Pendragon. Nice to meet you two

Kiana: *Chuckle* What ware you, the famous guy in legend?

Shirou: Yes

Kiana: You don't even have a proof

Shirou: You'll understand soon

Mei: Kiana, please just introduce yourself

Kiana: If Mei-senpai said so. Kiana Kaslana, a girl from Kasalana okay? A pure Kasalan

Shirou: Is that a noble family name?

Kiana: Heh, yeah. I came from a famous family with a warrior blood line. I could beat you with my Kaslana gun-kata in an instant!

Bronya: The Bronya doubt

Viewing a flashback of her attacking Saber with her cannon. The invisible air, his fast pacing and reflexes. She doubt that a girl like her would be able to defeat him in a whim... no, Saber is clearly undefeatable in her eyes

Kiana: Huh?! What did you just sa-

Mei covered her mouth to prevent her rudeness

Kiana: Am notb dobm yemt!!
            (I'm not done yet!!)

Mei: Pardon her, please. I am Raiden Mei... 

Bronya: Bronya Zaychick

Kiana: Alright then... let's go! but who's gonna take all these things?

A stack of cans was then revealed.

Shirou: Bronya

Bronya nodded she approach the stacking and matrix took the stacks of can into the project bunny.

Kiana: Woah

Shirou: The Power of technology is truly amazing

Mei: Yes!

Mei nodded profusely. While Bronya was focused something from her device. She picked up a signal from a mysterious air craft

Bronya: The Bronya picked up a signal. The Bronya must go above the high buildings to call the anonymous readings

Shirou: What is it Bronya?

Bronya: This can be our best escape route. It's an airship around 278.5m in length a carrier one

Mei: I heard about that ship... It's the hyperion. My father was one of its designers

Kiana: Woah! As expected of Mei-senpai

Shirou: Such infrastructure must be great in design. I heard things about your father

Mei frowned

Shirou: He's a guy whom never do such things. I've dealt people like him and just his eyes, I can tell he did nothing wrong

Mei raised her head.

Shirou: He's a great man... and people who accused him must receive a fair punishment.

Saber appraoch him and patted her in the head

Shirou: I swear... I swear I'll find the culprit of this and the true reason behind this disaster

Mei: You don't have to through this things

Shirou: I've failed to serve justice, to treat my people right, to treat my men as they are humans. This time, I. Arthur Pendragon will do anything! to act as the king I was supposed to be

Kiana: Eh... sounds kinda corny. You're not even King Excalibur himself

Bronya: Idiotka... The Bronya shall go now

Bronya look at me then nodded. She left immediately

Kiana: Anyways are you sure about her leaving? she might going to ran away with our foods

Shirou: For short time, I already know what kind of person Bronya is

Kiana: Why should I trust you?

Shirou: Yes. But anyhow. Let's explore the city shall we?

Kiana: It's dangerous

Shirou: Then let's scare for container and water. We need it the most

Mei: Yeah, he's right. But what about Bronya

Shirou: We'll be meeting her so do not worry

Mei: I see. Kiana-chan let's go

Kiana nodded whilst glaring at Saber. Saber just shrug it off. 

Exploring the city. He heard something flying. As well gigantic honkai beast, chasing them. Saber them(Mei and Kiana) hid first to one of the building. They observe him fight. Just a few slash of his invisible sword would instantly kill the giants. Without even efforts, he himself look like her threw a multi layered compressed air as to creating blade as it cuts the beast that he fought against. Two honkai beast approach him Both of them are Storm Templars with swirling lance and a transformable shield that can be transform into sword. As it two was on his side approaching him such speed. He jumped into insanely high grounds then dived. Blue energy particles gathered into Saber's invisible air then created a shockwave as the sword of King Arthur, The Excalibur revealed to the naked eye. He dived down in an instant. He was back on ground knelling. He stood up then swiftly slash his Noble Phantasm to his side as the beast the both cut into 2 pieces. Entered the building to where they hide

Kiana: What the... What are you?

Saber glare at Kiana for a slight second and ignore her question. 

Kiana: Hey! Don't ignore me!

Saber: Servant Class; Saber. Identity; King Arthur Pendragon. Also known as King of Knights. 

Kiana: I thought Excalibur is thin

Saber: I... have no comment on that... But things that are made from fiction or even history itself can be wrong

Kiana: Or is it that your sword actually not Excalibur huh...

Mei: Shirou-sa-

Shirou: Saber

Mei: Ah... Saber-san. My friend here is really... well you know

Saber: I understood her childish behavior. I too have once an acquaintance like her. But for now. Let's go to the top of the building

Mei: Yes

They all climb the stairs until the middle of a 25 storey building. 

Shirou: I can use my sword as a flare. It will cost greatly but please be patient

Kiana: That sword?

Shirou: Yes, I can cancel out my noble phantasm. 

Kiana: What do you mean?

Shirou: You'll know it soon. Miss Raiden, please restrict Miss Kaslana

Kiana: Finally! Some alone time with Mei-senpai!!

Mei: Yes

Kiana: But I wanna watch though...

Mei: You can't this is for our sake, Kiana

Kiana: Fine...

Saber nodded as the purple haired nods. Saber rushed to the top of the building then destroying the exit for the rooftop in a quick time. He raised the his noble phantasm as yellow energy particles gathered into his. While slowly draining his mana. He grunted as light beam came from the building and thus... people from an unknown flying object noticed the signal.

Hyperion

Operator: Major, We've got a beam of light! from Nagazora!

???: How much time we have left... otherwise this girl that midget talk about will die

Operator: I don't know but the plausible is just two days. 

???: How much honkai energy that emits from the light?

Operator: Around 987... 1098... wait... It's rapidly increasing!

???: I see. Speed up the hyperion!

All Operator: Yes Maam!
___________________________

12 minutes later. The True Noble Phantasm was cancel out yet weaken Saber quickly. However his magic core gathered honkai energy then converted it into mana. It gave back his ability to walk again and prepare for another battle to come yet risky to use the his noble phantasm. It was a long process but paid it off. He began to walk down the stairs. Arriving to where he left the girls. 

Mei: How was it?

Shirou: You won't know until they come

Mei: I see... but it's a guarantee right?

Shirou: Yes

Mei: It's relieving... Let's go now... I'm kind of thirsty

Kiana: Me too...

Shirou: Best place for that will be Convenient Stores. It's a lot here in japan so let's get waters there

Mei: Yeah. But it will be dangerous though 

Shirou: Don't waste any bullets... I'll take care of them

Mei: Wouldn't that exhaust you?

Shirou: I am trained to be a great warrior and to be the one and only true king of britain. After all I am the King of Knights.

Kiana: Shut up King Arthur wanna be

Shirou: Have you not seen my Noble Phantasm, because it was clear that you seen them

Kiana: It's whatever. Let's go!

Saber and Mei sigh.
___________________

Upon arriving to one of the convenient stores. Gigantic honkai beast are as well there. Saber fought them just for the two to drink water. Due to the shining blade excalibur and its foreign energy it emits an army of beast was then attracted to it and one of the beast slipped as they saw Mei and Kiana. 

Shirou: This is bad...

Luckily Bronya came in. Bronya's Project Bunny 19c replaced the cannon with a spear then clashes with the beasts. Not long after she lost but Bronya was then protected by the PB 19c. Kiana took the opportunity to run with Mei and so she took her hand then another templar rushed to them. To protect Mei, Kiana turn herself in

kiana: If you keep thinking about Bronya specially Saber... Kiana might get jealous!

Shirou: KIANA!!!!

Mei: K-Kiana....

Mei screamed as shock wave errupted. More beast is even attracted. Saber is now mauled by an army of beast. His armor are all damaged as well he was all bruised up. Saber disable the armor then performed an AOE attack as all beast that mauled him died as it explode. he then escape as fast as possible until he got the perfect range to unleash his True Noble Phantasm

Shirou: You foul beings... You've hurt enough people... I shall... I shall punish you with my divine light!!

The Excalibur shine brightly as he raised it above. A pillar of light then exceeds. The beast stopped moving as they were distracted on how powerful the light looks. The finally awaken herrscher was as well captivated by the Excalibur's beam of light while holding a shield barrier as other mauled her

Shirou: EXCALIBUR!!!!

He dived down the divine sword and the army of beast instantly burnt to ashes. Bronya in the other hand quickly left before she gets distracted. Meanwhile the herrscher struggled to keep it. It's even breaking burning her with the divine blast that the Excalibur produce

HoT: It's... him... What... the hell... is he?!!

The blast ended. Saber noticed that they were still on the blast radios. His eyes widened he rushed to the two even though he was weak. Slowly the his mana was getting infected by honkai energy. 

HoT: Just who the hell are... Shirou?!

Shirou: It's you... please... Let me heal you

HoT: Heal me?! Can you even ressurrect the dead?

Shirou: AVALON!

A scabbard floats as it glows. Pink veins now started to climb to his neck as he removed the avalon

Shirou: I can heal her... let's settle our fights later but for now, We need her alive

HoT: If you won't heal her then I'll kill you!

Shirou: I'll take on that offer, Ruler of Thunder

HoT gently dropped Kiana's body Saber rushed to her body and from there he placed the Avalon above her then slowly drop it as it entered Kiana's body. Slowly healing Kiana on the process. Saber in the other hand began to weaken. It was fast. Kiana slowly regained back her consciousness. The first she saw was Mei. She then hug her. The herrscher was still shock to see her alive and well

HoT: ...I'll... I'll repay this kindness once I have enough resources... Shi-

*thud* 

Saber fell whilst his breathing were hoarse

HoT: Shirou?

A large structure came down and from lowest parts a door opens 

HoT: I will remove the honkai radiation off you... just give it a time, Shirou... rest well

Kiana: Mei-senpai! Why are you thinking about him?

HoT sigh before switching out to the original ego

Kiana: Wait what happen to him?

Mei: KIANA!

Mei cried and hug her tightly. Then another one dead so she approach him and check if Saber's alive. She was relieved but the only thing that bothering her. Is the pink veins on his cheeks and as well his heavy breathing

???: My my, Sir knight has fallen. Valkyries check his vitals also take the girls in

Mei step in and widen her arms

Mei: I won't let my friends get hurt

???: Says the one who's a herrscher... Anyways I can assure you that we won't hurt your friends , young girl. You have no choice of escape but us

Mei: Fine...

???: Good
__________________________

Hyperion

After getting picked by helios, They are now currently in the great battle ship, hyperion. The girls is now asked the current events by a specific red haired woman. Soon after a loli-ha

[Theresa: WHO ARE YOU CALLING LOLI HAG?!

Reigch: Haha... long time no see...

Theresa: Reigch... say it... or else...]

A "matured" woman yet has a questionable features of that of a child, Approach the two

???: Well well

Mei: Where did you put, Saber-san?

???: In the infirmary but we have important matter to announce before you two see that living legend

Kiana: So tell us now

???: We've known each other since that 2nd war broke out, Kiana. How you not know me?

Kiana: I dunno... who are you? little brat

???: Brat?

Theresa summoned her divine key then chains projected into Kiana however... the Avalon protected her as it appears in front of her

Kiana: What the hell is that?

???: Just as expected

Mei: What are you trying to do?!

???: Just a little experiment you see. The scabbard that he planted on Kiana will act as a defense mechanism from threats not to mention it has a healing capabilities... Such an interesting sheathe.

Kiana: Wait... Why would he plant this thing to me?

???: To heal you of course...

Kiana: Maybe I was too harsh on him...

Mei: Pretty much

Kiana: You should be defending me! Mei-senpai!!

???: Anyways... I'm Theresa Apocalypse and I am in charge of the Far East Branch of Schicksal

Mei: You can do whatever with me now

???2: If killing you is what you meant. Then you're wrong

Theresa: C-Captain?!

Theresa: Wait... why aren't you putting your uniform

Captain: Cause why not?

Theresa: You failure perverted f*** I swear to god one more time you won't wear your uniform, I'll fire you

Captain: Your grandpa will bring me back again... also just because I mistakenly went to the wrong bathhouse doesn't mean I'm a pervert ,plus I work harder than you. You even put some paper works on me. Even when I'm busy you will order me to buy you bitter juice in which in return you don't even thank me.

Theresa wasn't hit with reality but worse than it.

Captain: Anyways, Welcome to hyperion, go cozy and no complain

Mei: Why?

Captain: What?

Mei: It'd be better off if you'd kill me!

Kiana: Mei-senpa-

Captain: We are not murderers and also sure thing that you could hurt thousands however we are meant to help people not kill them. We serve justice to the weak and make them stronger if they want to. I'd be even more honored if you join our academy

Mei: Huh?

Kiana: Wait why the hell would we join tha-

Captain: Daughter of Siegfried please shut the f*** for once? Anyways you both can contribute to each other, training to together in a way that you both can protect each other. Is it that a good deal?

Theresa: And in return, Kiana... I know where your father is. if you became an S-

Captain: No she doesn't it's just persuading you to join St Freya. Even I tried to find that trouble maker but couldn't.

Theresa: You just ruined it

Captain Emiya ignored it

Captain: However... Saber planted the Avalon on you in order to protect and heal you. Now Kiana, Saber has only few hours lives. Because of you

Kiana: Huh? Did he just?

Captain: His Noble Phantasm took all his mana away and replace it with honkai energy because his magic core was confused. And now just a bit of it draining by infection that infected him. What would you do now? To repay his kindness. There are doctors that you can ask

Kiana: ...Why? Why would he do such thing?!

Captain: Just like Arturia... he's... special... he will do reckless things just to save one person...

Theresa: Hold up... I need some explanations

Captain: Yeah... we really have. Anyways, set some surgery plans because Miss Raiden need it

Kiana: Why?

Captain: It may sound evil but it's the only way. After all Herrscher is nothing but a stone when the host die, Isn't it? So we'll plant a micro bomb in her heart to scare her alter ego

Kiana: But!

Captain: No buts. You'd slowly kill her by beating her up. For now think about Saber... You wouldn't something to happen what happen to me

Kiana silent

Mei: I'll take it

Captain: Good, Welcome aboard herrscher of thunder. I, Shiro Emiya welcomes you as one of my valkyries, I'll be counting on you. And also... good luck on helping Arthur... He'll die if you both don't hurry

Theresa: Ahh... Sorry, Ever since Emiya came to us, he's been like that. But he's caring and gentle when you know him... He seems to have a rough past...

Kiana: But Saber... how about him?

Theresa: He's so much little time... Spend it with also... Bronya you can come out now

Bronya: Da...

Bronya came out

Mei: Bronya!

Bronya: Mei-neesan...

Mei rushed to Bronya and hug her. Bronya produced a tears despite being emotionless. Mei couldn't tell whether she's happy or not

Mei: Bronya?

Bronya: Is... Subject Saber... going to die?

Mei: Yeah... there's probably no cure for his illness

Bronya: I... understand... Bronya shall go his bed

Mei: Yeah
_________________

Few hours has passed there's nothing they can do about the infection. If only they were smart enough maybe they could help him. Kiana on the other hand ask people how does an infection work. She listened to the scientist and doctors even though she's struggling hard to understand. She learned how honkai infection works even though she didn't know human body parts are, Honkai energy over dose then how herrscher works. Finally she got her answer she rushed to Mei who's talking with Bronya

Kiana: huff... huff... Mei-senpai!

Mei: Kiana-chan... what's the hurry?

Kiana: I found the cure!

Mei: Huh?

Kiana: You're a herrscher... We still can save him!

Mei: Saber?

Kiana: Yes!

Mei: But how?

Kiana: Honkai energy suction!

Mei: What's that?

Kiana: Sucking up honkai energy that infect him!

Mei: But how?

Kiana: The herrscher!

Mei: But!

Kiana: Please! It's the only way...

Mei: Fine... Bronya, stay here okay?

Bronya: Nyet

Mei: You need to

Bronya: To trying a release the herrscher back. We need a vehicle. Maybe Helios is enough, The Bronya be monitoring it and try to drive it the least

Kiana: Okay! Let's go!
_____________________

Bridge, Hyperion

Captain: Finally... you both came

Mei: We need a ship

Captain: Why is that?

Mei: I'm releasing her back

Shiro smirked

Shiro: I know you'd ask this. Anchor up! Deploy the Helios!

Operator: Captain?

Shirou: Orders are Orders

Operator: Understood. Cease the thrusters!

The hyperion halt in the middle of the its sail. Then deployed a Helios

Captain: Rush to the the deck and jump off. Take his body too
_______________________

Kiana and Bronya went to the Helios first as Mei took his body. She explained things and so she carried Saber's decaying body. She rushed then used bit of her herrscher powers to float and land them both safely. 

Helios, Bridge

A chibi appears as it floats after Kiana attempting to control the helios

Ai-chan: Heya!! Ai-chan dayo~ You're reliable AI!

Kiana: Ai-chan drive us far far away from Hyperion

Ai-chan: Got it! Helios! Let's go!!!

Bronya Stayed as Kiana left after nodding to each other

The Helios then travelled in a straight line. Saber has only few minutes left. Veins now covered his body. The Helios arrive the their destination. Kiana and Mei were on the deck of the ship as they lay Kevin gently. Mei was nervous, Kiana took her hand

Kiana: Don't worry... I'll beat you up again, if things happen... For Saber

Mei: ...Yeah... for Saber

Mei closed her eyes thus entering her alter ego's domain

Mei?: You came back

Mei: I need your help?

The alter ego already know about this

Mei?: I'm grateful for Shirou... For I need to save this guy. We may not see again each other... but sooner if not later... You'll be joining me...

Mei nodded. A shock wave then erupt from Mei's body. She open her eyes, it was now red. She simply touch his chest. Then a sudden surge of energy emits out off Sabers body. It even overwhelmed the herrscher. The energy then created honkai beast... it was rather new yet same physique. 

Mei?: I'll take care of them. Don't worry. 

Kiana was still silent and dropped off her hand

Mei?: You cannot die yet... you need duel me as promised!

Kiana: Shouldn't you... tell that to me when I was the verge of death?

Kiana ask

Mei?: Shut the f*** up

Veins started to reverse its effect. She kept sucking the honkai energy then released it as the energy as she raised her other arm. It was still not half. He will still infected. Around 73% of honkai energy was taken out off his body it kept increasing and decreasing... Most of his mana are infected by the honkai energy. And not knowing how much mana Saber store she was struggling to keep up as the infection keep infecting his mana. The energy that was ejected off then created an extension; better weapons, truster even the design itself to the Helios as one of saber's ability.

(Kinda added since Saber literally can transform the motorcycle into cooler one and is mana powered in this situation its honkai powered just like selene)

The same chibi then appeared into the deck as it materialize into a holographic entity

Ai-chan: Wahh! Helios has now new extension. better hovers, weapons and all! Can Ai-chan use them?

Kiana look at her surrounding Beast were hit by thunderclap per 2.5 seconds

Kiana: Ai-chan. if you're truly the greatest AI! Then give you all!

Ai-chan: Yeahh!! Ai-chan will protect you all!! Witness honkai! The power of humanity!

Beams of destruction was projected into the deck as force shield created to them, protecting them from any harm. The wave of beast slowly die out but kept replacing by another wave. Only few liter worth of mana are left to Saber before "he" come back. The herrcher speed up the process in which she struggled 

It kept draining and draining, The herrscher tears out as she doesn't want him dead. 900ml left. She was close, now 500ml left. She's able to reach the foreign energy mana. Now that 300ml is left she successfully saved him. Slowly clean honkai energy absorb into saber's body. The herrscher lays on exhaustion while still Helios fired destructive beams

Kiana: We did it!

HoT: Yeah... we did it... ...Kiana...

Kiana: Yes?

HoT: Can you... huff protect him for me?

Kiana: Heh, I will do. If Mei-senpai said so

HoT: Good girl... 

Kiana blushed a bit. The herrscher fell asleep.

Ai-chan then appeared back

Ai-chan: Ai-chan just downloaded a new reader! The honkai energy that emit in total was 10,987 hw which was outstanding specially for a guy... Wow... as well analyzing his "EX-...-KALIBAHH!!!!" was around 9,835 hw... what an outstanding fire power! I'm sending the stats in hyperion okay~

Kiana: Yeah... tell them that we're all safe too and just drive us back

Ai-chan: Hai! Understood, Kiana-kanchou!

Kiana smiled a bit

Kiana: We saved him... even though I'm dumb and useless... We still saved him

Kiana closed her eyes. She was as well fell back asleep

Hyperion

Theresa: So? What was this Saber-Saber Arthur-Arturia all about?

Captain: Did you remember the day you found me?

Theresa: Yeah there was weird cult-like circle stuff then glowed in front of me. Then you appeared

Captain: I'm speculating something... 

Theresa: What is it

Captain: Servant such as myself is probably summoned to this unknown world. Though we were originally to have master, you don't have the servant crest nor anyone does... So in conclusion. We are randomly summoned here or perhaps holy grail or something

A katana appeared to his hand. The handle was red and as well its blade with its sheathe

Captain: This is a noble phantasm. A heroic spirit's signature weapon. They are equal to divine keys and as well the user are equal to pseudo-herrscher's and still can be infected by honkai energy when trying to absorb to heal themselves, the servants. For my situation however, I used my full potential and weaken myself in the process to just try and cease the 2nd herrscher

Theresa: I remembered that

Captain: In this world that is called an "illusion" but for us it's called a reality marble.

Theresa: You haven't mentioned the name and stuff

Captain: AHh yes. Servants came from legend, myths or real life; whether from the past, future or even present. They needs to be the hero. For example; Cecilia Schariac can be as well a servant if incantation is used to her, most probable for her is a Lancer type because of the divine weapon she wield, a lance. Anyhow Real heroes or not, myth or legend. It's either. 

Captain: As well I haven't talk about servant classes yet. Saber is a close quarter servant, Archer is good in range though it kinda depends, Assassin - lurker of the dark could kill you in an instant but as long as your servant is there with, you're safe. Caster is a mage that cast incredible mage craft. Then Berserker which its name alone does explain itself. They are the 4 cardinal heroes, 4 heroic spirit in each 4 classes

Theresa: I understand now

Captain: Although

Theresa was just about to leave

Captain: I don't remember being a servant

Theresa: What do you mean?

Captain: Previously before I leave my world and find myself here. My signature weapon at that time was Archer's signature weapon; Kanshou and Bakuya. A machete that represent yin and yang and in here it's the Murasama katana. You know what it meant as it means  "demon sword" and plus I'm a saber class. That's it

Theresa: I see... I'll see you soon, Captain

Captain: Yeah... *sigh* I don't know how to look at Saber from now on... Kinda weird to think that she's now a guy. A weird reunite
