I walked back to see my home thrashed. I was worried cause if Y/n is gone, where is he? I couldn't find him anywhere, I kept looking for him around the house. Y/n where are you? until I saw a frying pan near the spot where he rested, he was kidnapped and where? I got outside and ran to find him

Keine: Y/n! Where are you!?

I looked around the village to find him

Timeskip

I couldn't find him on the human village, I was exhausted and sat down on a bench and took out a sigh

Keine: Where are you Y/n?

I'm on a verge on tears since what if: He's dead or worse?

???: It's too early to be on a verge of tears

Keine: Huh? What do you mean?

I looked at my right to see a man that wears chef clothing, and glasses. His hair color is white, and his eye color is black. I believe i'm talking to Nail A.K.A Miyamoto Musashi

Nail: I can tell you where he is but this shouldn't do. Meet me at my house Keine

He walked away, and I walked away to the opposite so that I could prepare everything I need

Timeskip

I walked inside to Nail's house and I saw him waiting on me while sitting on the chair while there's a table in front of it

Nail: Come. Sit down Keine

I walked to the dining area and sat down in front of Nail

Nail: If I recall. I know where Y/n is at

Keine: Where? WHERE!?

Nail: I can tell you but you wouldn't like it

He showed me a file

Nail: This contained the evidence that where is he

Keine: That doesn't answer my-

Nail: He's kidnapped at Mokou's place

I wasn't shocked about it but i'm clearly pissed about those words, then he slid me the file he showed to me. I opened it to see the pictures of Y/n being tortured by Mokou. Now i'm even more pissed about it

Keine: How did you get these information?

Nail: I didn't

I looked at him

Nail: Someone did it for me, and I was notified about it then they gave me the photos that I gave to a friend. Of course I paid them about it

Keine: How did you get to do all of these?

Nail: It's a trade secret

Keine: Damn. I guess that's all I need to know

Nail: You don't plan to go to her directly don't you? I don't think you could fight her alone

Keine: Then can you help me?

Nail: Yes. Since he's badly injured, but I'm not enough yet

Keine: Alright then. We shall find more people to help us

Nail: I accept that

Timeskip

Me and Nail walked our way to Eientei so that we could recruit more people to fight with us until a certain girl with blue hair went to our direction

???: Hi ancestor

Nail: I'm not your- *Deep Inhale* Ancestor damn my chest hurts

???: Where are you going? Can I join? Are you okay?

Nail: First answer to your question. None of your concern, Second. No, And third. No since lung cancer pains me again

Keine: But na-

Nail: She cannot fight on her own. She needs a guardian to fight for her

???: Please? Pretty please?

Nail: *Sigh* fine then

Ichirin: YAY! Oh and by the way. I'm Ichirin Kumoi

Nail: Let's get going. And Unzan?

Ichirin: He's back home. Guarding

Nail: Let's continue

Timeskip

We three reached to Eientei and we tried to look for the residents and we found them

Kaguya: Well if it isn't Nail, Nail's annoying Descendant

Nail: She's not my Descendant!

Kaguya: Whatever. And Keine, what can I do for you three?

Keine: I need your help defeating Mokou bring Eirin with you if you want to

Eirin: And what's in it for us?

Nail: Well. You can screw around from insane Fujiwara No Mokou if you want to

Eirin: That's not enough

Nail: Hey! Your Hourai elixir didn't cure my- *Deep inhale* Lung cancer so you better join us right now

Eirin: Or what?

Nail: Or i'll tell everyone that you tried to-

I saw Eirin blushing

Eirin: OKAY OKAY I'LL JOIN IN!

Nail: Thank you

Timeskip

We all went to her place at night. I turned into a hakutaku since it's nighttime

Nail: Fujiwara No Mokou come out before we come in by force! We got you surrounded

Mokou POV

Looks like pests are in the way of my love for Y/n

Mokou: Don't worry Y/n. I'll be gone for a while

I said to my Y/n but he wont respond since he's asleep anyway. I walked outside to see five pests on my Environment

Nail POV

I summoned my Katana and prepared my fingernails just in case

Mokou: If you want fight. So be It!

We all charged at Mokou

Timeskip

Keine was injured. Ichirin was exhausted, Kaguya is unconscious, Eirin tried to get up, and I'm out of fingernails but I slashed at Mokou but she grabbed my katana with her bare hands

Nail: Damn it!

Mokou: How pathetic Nail. A guy who gained immortality by drinking the hourai elixir like i did but it didn't cure your lung cancer

She pushed me but my shoes grind on the ground to stop it

Mokou: Is that all you have you pathetic so called fighters?

Nail: No. It isn't

I opened a portal to summon more help from chaldea. This is the last of my magic. So it must not be on waste, It revealed to be a grey haired-ish girl and the white haired guy, I know him so it must be Sanson. I'm lucky, then I stepped unconscious

Sanson POV

I looked around to see five people injured, unconscious and vice versa and I saw a girl who's insane judging on her looks

Sanson: What happened?

???: So is this what Nail summoned? How pathetic

I looked at Saber alter

Sanson: Saber. Keep her busy while I'll heal the injured

Saber alter: Got It. This will be a fun ride

Saber Alter POV

I prepared my armor on and Excalibur Morgan, while that happens. Explosions appeared around me

A/n: She won't have the mask and play "She rules the battlefield during that"

Saber Alter: Shall I have the name of my playmate?

Mokou: If you may ask. Then I'm Fujiwara No Mokou. And you must be Saber?

Saber Alter: That's what people called me. Well now. Shall we play?

Mokou: We shall then

I see Mokou Charging at me. When she gets close to me I swing my sword to knock her back. I used mana burst to charge up more power when I hit her

Saber Alter: Pathetic

Meanwhile on Eirin POV

The guy who I tried to Ra- I mean help him came back, He introduced his name to us and he healed us. I told him on what's going on and he told me that His friend is dealing with her, I wonder what's going on right now

Saber Alter POV

I looked at Mokou which she's getting exhausted but i'm not yet done

Saber Alter: What's wrong? Are you having a problem fighting me?

Mokou: DAMN YOU!

She charged at me and I used Mana Burst on Excalibur Morgan and slashed her in half. I saw A portal filled with eyes appeared In front of me

???: Throw her in the gap to win the battle. She cannot be killed

Saber Alter: Very well then

I looked behind to see Mokou charging at me. I jumped behind her and kicked her inside the gap, it suddenly closed after

Saber Alter: What a pathetic fighter she is and yet she called me "Pathetic"

A/n: End the music here

I walked back to the others which they told me to look inside, I looked inside to see an injured boy cuffed. I destroyed the cuffs and took him out

Timeskip Keine POV

We all got back in Eientei and I waited for the results, then Eirin came out

Keine: How is Y/n?

Eirin: He'll be fine. He need some rest

Keine: Thank you so much

I walked to the people that helped us and I bowed down

Keine: Thank you for your help

Henri: Don't mention it. We'll be happy to help but she's happy to fight the strong one, right?

Saber: Indeed. We'll be going now

I looked at them and they walked their way to the gap

Nail: Yep. Glad I could help

Keine: Thank you Nail

Nail: Go see him, He might be awake

I walked to his room and I saw Y/n Awake. It made me happy that he's awake

Y/n: Hey Keine

Keine: Hi Y/n

Y/n: Thank you for doing this mess for me

Keine: Of course. And now like I said

Y/n: You need me to get healed so I could marry you?

Keine: Of course

Y/n: I will. But can you be around me until i'm healed

Keine: I will

We both made a passionate kiss

Timeskip after marriage

I walked my way to my room and I saw Y/n awake

Keine: Hey dear. You're awake?

Y/n: Yeah. What are we going to do?

Keine: Well. Can we cuddle in bed?

Y/n: Sure

I lay down next to Y/n and we wrapped our arms in each other

Y/n: I love you Keine

Keine: I love you too Y/n. If you're captured or anything worse

Keine: I'll be going through hell to save you

The end

A/n: There JM126434. I made the sequel now. And I got my servants involved in this mess
