That's right! DekuMidoriyaXT_V2 dared me to create a MHA x DxD book! I will deliver.

Izuku Midoriya. A friend and fellow classmate to all of class 2-A and the 9th successor of One for All. A quirk passed down from one person to another, making it 2x as stronger as the previous. Currently he has 35% of OFA he can control, after All-Might's retiring, he made himself a regiment that pushes his limits to the test.

Let's take a small year gap back shall we?

FLASHBACK!

Toshinori: Look Midoriya. I know that I won't be able to help people and save the day since my final battle with AFO. The Symbol of Peace has stepped down, now it's your turn to step up on the pedestal for being the Symbol of Pea- no Symbol of Hope!

Izuku looks at Toshinori tears swelling in his eyes. He hugs Toshinori crying all the tears he pent up on emotions.

Izuku: W-will you still be t-there to help me?

Toshinori: Of course. Your determination alone is something that this world needs. Come my boy...let us make a greater future for all of the citizens of this world.

Izuku: Now that...is a true hero's prosperity.

He smiles while turning his head looking up to the stars as a comet flew by leaving a blue icy trail behind it. The comet soars across the empty darkness of space...what a beautiful sight.

Toshinori: Now this is what I strive for. Peacefulness and serenity. Your training will be doubled... Are you ready to handle the fate of the world on your shoulders Midoriya?

Izuku: A friend for them, a hero for all.

Toshinori smiles.

FLASHBACK END!

Izuku: It's been a whole year already, but it feels like I've been here all of my life. Time to give it my all!

He steps into Class 2-A with a familiar teacher in a sleeping bag.

Aizawa: Ah! Problem Chil- holy of all things-! Why are you so tall and built now?!

Izuku: U-uh...I was training throughout the break and this is the result...

Katsuki: Damn nerd!

Ochako: Deku-kun!? You look like a body-builder!

She says as she feels Izuku's arm while another figure grabs his other arm which was none other than Tsuyu.

Tsuyu: Midoriya-chan, how did you get so...handsome?

Izuku blushed. Since when did Tsuyu get so touchy with him?

Izuku: P-probably from the work-outs I do...

Aizawa: Girls get off of him. Now problem child, you have been requested to see Eri-chan at Nezu's office. Per say, here!

He tosses a candy apple at Izuku who catches it. Why did Aizawa tossed him a candy apple? For Eri of course! Eri loves apples! From the first time she has eaten one, she knew that apples were her snack from the get-go.

Izuku put the candy apple in his bag and walked to Nezu's office. Which the girls seemed to pout with an audible sigh.

A few minutes later, he reaches Nezu's office and slowly opens the door...

???: Onii-chan!

Izuku opens his arms as he catches Eri or his little adopted sister.

Izuku: Hey there Imouto! I got surprise for you from Aizawa-sensei!

He pulls out the candy apple as she has stars in her eyes.

Eri: Apple!

She takes the candy apple from Izuku's hand and unwraps it and nibbles on it.

Kawaii Desu! (I know you are either smiling or cooing over Eri!)

Izuku: Don't eat too fast or it won't last long.

He ruffles her white hair while she sits on his lap.

Nezu: My, she enjoys apples so much, I might have to buy 2 crate fulls so her stomach can be satisfied.

He sips his coffee.

Nezu: How is your progress with OFA?

He puts his coffee cup down staring at Izuku.

Izuku: I've gotten to the point of 35% without my bones breaking apart. Black Whip doesn't hurt as much as it used to.

Nezu: Magnificent! If you keep this up, then we can surely bring back some hope for the people. Keep working hard Midoriya-san or should I say future Symbol of Hope.

Izuku sheepishly laughs.

Izuku: You know I will sir. I just wish I can enjoy my youth even if it's for a short amout of time.

Nezu: That can be arranged. I've seen your schoolwork progress and you have done all of your next year's work as well. You really are smart Midoriya-san. Take a 5 week break from school. Although you are expected to train.

Izuku: B-but sir, I can't accept this! I still have t-

Nezu: Listen Midoriya-san, like you said. You want to enjoy your youth yes?

Izuku: Of course.

Nezu: Then take the 5 week break. I'm contacting Aizawa-sensei to notify that you are taking the break.

Izuku: I-uh.. Alright. C'mon Eri.

He puts her on his shoulders and walks out of the office.

A few hours later, he reaches his mom's apartment who allegedly hugged him hard. It's been so long since he last saw his mom and here she is looking like she was more slimmer and beautiful.

Inko Midoriya, his mother, had lost a bit of weight when she started to work out. She changed herself for the better. If her son was moving on and getting stronger why can't she?

That's what she did to get so slim. A certain point of time she adopted Eri officially making her Eri Hope Midoriya. (Yes I chose Hope as her middle name cause why not?)

Tears were shed here and there, keep in mind that both mother and son cry a lot.

Inko: So the principal gave you 5 weeks for accomplishing your 3rd years assignments ahead of time even though you are in your second year? You really surprise me Icchan.

Izuku waves her off.

Izuku: It's not that big of a deal. I mean he did say that I have to train my quirk.

Eri: Onii-chan is super powerful with his kicks and black whips!

Black whips? When did her son get into BDSM?

Inko: Black whips...?

Izuku: So...the black whips are part of my quirk. They can grab anything that isn't too heavy.

He uses one tendril to pick up a frying pan.

Thank goodness that her son wasn't into BDSM.

Inko: So you're telling me you have 2 quirks? B-but you said that you had a strength-enchancement quirk?

Izuku: W-well it came out of nowhere.

Eri: Onii-chan, I'm sleepy...

She slept in his arms. Adorable...

He carries her while putting his wallet inside his pocket.

He walked upstairs before a sudden rumble shook everything around causing debris to fall down. On instinct he covered Eri with his back without knowing he and Eri had been consumed by black energy.

Inko stirs up into conscious as she sees the damage around her.

Patting off any excess of dust, her mind went into overdrive. Where is her son? Where is her daughter?

She used her telekinesis picking pieces of her apartment to the side.

Inko: Icchan! Eri-chan!

She kept looking until she spotted a green piece of hood...

ICCHAN! ERI-CHAN!

Izuku wakes up with Eri still a sound asleep in his arms. Good thing he took most of the debris or...let's not think of what would've happened.

He grabbed his bag and luckily his wallet and hero suit.

Carefully he stepped out and limped his way out carring Eri in his arms.

How lucky they survived. But when he reached into the street, he saw what surprises him.

It's nighttime and not daytime.
Whatever happened made it quite difficult to understand.

He overhears a conversation.

"Would you die for me Issei?"

The brown haired male looked at the girl.

"Can you say that again Yuuma?"

"Would you die for me Issei?"

The girl then transformed into a fallen angel with an erotic clothing.

Issei: W-wait! Hold on! Y-you literally serious of killing me Yuuma?!

Raynare: Fucking pervert! Of course! My job is to kill you!

She makes a spear of light and throws it at him.

'Is this how I'm going to die?! I-I don't want to die!'

A black whip wrapped around his waist and pulled him towards a bush.

Raynare: Who's interferring my job!?

Izuku: That would be me!

Raynare:'He has a sacred gear?!' You really think you can beat me!?

Izuku: All I have to do is try right?

And with that he launched himself to Raynare and decked her in the face with the soles of his gamma suit.

Raynare: Your dead! You hear me?!

She summoned more spears of light and threw them at Izuku.

Izuku: '8%' Air cannon!

He flicked his finger causing Raynare's wings to go unbalance making her fall down.

Raynare: Damn you!

Izuku: I think not! Lights out!

He struck her as a purple outline encased her as she laughs.

Raynare: Next time! I'll get you!

Issei: H-holy shit... A-are you a legit super hero?

Izuku: I'm a hero in training. Where's my sister?

Issei: Right on my back. We should probably check your shoulder though...

Izuku: Wait huh?

He notices the blood coursing down.

Izuku: We should...

A girl with crimson hair is seen staring at both Issei and Izuku as a purplette is intensely staring at Izuku.

Rias: Change of plans Akeno. We'll make sure that those boys will be ours.

Akeno: Indeed Rias. I'm interested in the green haired one. His power seems so...so punishing~

She moans a bit while wiggling.

Rias: It does surprise me that they are both still human. It's going to be a good year for us this time.

Akeno: Agreed... The faster they are in our club, the faster I can cuddle my green gem!

Rias: It's time to hit the hay now. See you tomorrow Akeno.

Akeno: Later Rias.

She licked her lips softly. A green gem is what she needed since that was on her list...a list of lust that is.

I'll be making this a 2 parter cause why not? Ciao!
