Author here! Since DekuMidoriyaXT_V2 is a bit late on schedule... I'll just twist and tweak this fanfic a bit more. Enjoy!

Issei carries Eri on his back as he walks a bit slow so the Izuku can catch up.

Issei: My house is just around the corner Midoriya. I'll get you patched up in no time.

Eri: Will Onii-chan be ok?

Issei: He'll be ok Eri-chan. Right Izuku?

Izuku gives a thumbs up before he grips his shoulder a bit tighter to slow down the blood from his wound.

Izuku: I'll be just fine Eri-chan.

They make it to the Issei's house as he knocks on the door.

A woman opens the door and sees Issei and the other two unknown figures. One small child on his back and a teenager not older than 17 with his shoulder bleeding through his apparel.

The woman's name is Miyumi Hyoudou, Issei's mother. She brings all three of them in while searching for the medkit.

Issei: Izuku, you have to tell me how did you do all of that?

Izuku: Do you know what a quirk is?

Issei: What the heck is a quirk? Is it a mood or something?

Izuku: Like a superpower.

Issei: Superpowers? Similar to this?

He pulls out a manga dubbed One Punch Man. He points to the character Fubuki.

Izuku: Somewhat similar to Fubuki. However mine is more like Saitama except without one punch.

Issei: Holy...'Can't say that since there is a kid here...' apples.

Eri perked up from the word apples.

Eri: Apples? I want apples!

Issei points to the bowl of fruit.

Issei: It's in the bowl. Let me get you one.

He stands up, grabbing a red apple and hands it to Eri making her smile widen.

Eri bit into it with a satisfying crunch.

Miyumi came back with the medkit tending to Izuku.

Miyumi: Where on earth did you get shot...Izuku right?

Izuku nods his head.

Izuku: I protected your son from a girl who was trying to kill him. Although, she left while I was clutching my shoulder.

Miyumi: Is your sister alright?

She said with worriness.

Izuku: She's doing just fine. It pains me to say this...but we both don't have a home and I only have about 10,000 yen on me.

Miyumi: I can't send the both of you out there.

Issei: I agree! You did save my life, stay here with us. We can sort this out in the morning.

Izuku: Two questions. Is there a highschool nearby and who will be able to take care of Eri while I'm there?

Miyumi answered quickly. She always wanted a little girl to dress up.

Miyumi: I'll watch her. The school you'll be attending is the same one as Issei's. Kouh Academy used to an all-girls school until they got a few boys to enter the academy.

Issei: It's pretty chill. The girls though might be a bit rambunctious.

Izuku: When will I start then?

Miyumi: Leave that to me dear. You might as well be a part of the family as well as Eri.

Izuku: Thanks for this!

His arm slowly begins to heal as the night deepens.

It was now morning as Izuku puts on a uniform that is a bit tight on his build. He wore a green undershirt with a blazer and his iconic red shoes.

Issei: Ready to go bro? (I'm making Issei not as perverted and he won't be with the other two of his friends.)

Izuku: All set. Let's get going.

He grabs a spare bag and kisses Eri's forehead.

Izuku: See you soon Eri.

Eri: Bye Onii-chan!

While walking to the entrance, a few whispers and cat-calls were pointed to Izuku.

Issei: Figured as much. You might be tied to Kiba in the looks department.

Izuku hides behind Issei as the girls scream.

"KAWAII!"

Male1: Not another damn Kiba!

Male2: He better not take Akeno-chan! (Oh he'll take her alright...)

Issei scoffs at them. Izuku follows behind him.

They make it to the student council room. Issei knocks on the door as Saji opens it and lets them in.

Sona: Ah Hyoudou-san, who's this?

Issei: A transfer. He's my long lost cousin. Sona this is Izuku.

Izuku: It's nice to meet you Sona-chan. Do you have my schedule?

Sona feels a lot of power coming from Izuku seeing as he looks innocent.

Sona: Here. Your schedule is the same as Hyoudou's.

Issei: Nice. C'mon Izuku.

Izuku follows suit. Sona looks at Izuku's figure before shaking off the thought. She'll have to keep an eye on both of them.

Izuku looks around with his eyes darting everywhere observing.

Issei opens the homeroom door as he sits down looking out the window. Izuku sits behind him.

Rias and Akeno come into the classroom asking the teacher to get 2 students.

The teacher allows them too.

Akeno: May we have Issei Hyoudou and Izuku Midoriya follow us please?

Izuku and Issei get up again following Rias and Akeno.

Izuku: Hey Issei?

Issei: Yes Izuku?

Izuku: Who are these two?

Rias: You'll find out soon enough Izuku.

Akeno: Ara~Ara~ you are quite curious my sweet green bunny~

Izuku: B-b-bunny?!

He turned bright red looking down making him a bit more adorable.

Akeno:'LET ME HAVE HIM RIGHT NOW!' KAWAII!

Rias: Akeno calm down.

She calmed down although she took a picture of Izuku...for purposes.

The Occult Research Club, in disguise, it's more of a devil's hideout. But Izuku and Issei don't know that.

The four of them sat around a table with tea served by Akeno.

Izuku takes a sip of the tea while Akeno sits next to Rias.

Rias: Alright... Now. Do you two know about the supernatural?

Izuku: Is this about the girl last night? Raynare? She had wings and she was a fallen angel.

Akeno: She's a stray, fallen angel yes.

Issei: You mean to tell me she has powers as does Izuku?!

Izuku widens his eyes.

Rias turns to Izuku in question. What kind of powers?

Rias: So you have powers too? I wonder what they might be...

Akeno: I hope they have something to do with lightning!

Izuku backs up and subconsciously uses OFA at 10%.

Izuku: I'm guessing you two are devils! Issei get behind me!

Issei does what he was told as his hand starts to shake uncontrollably as a red gauntlet appeared.

???: Who the hell woke me up with that much power?!

Izuku: Of for kami sake's...

Ciao!
