As Kota and Eri removed Nightclaws helmet everyone saw a handsome Izuku.

Izuku: Guess who's back....

Class 2-A: Deku! Midoriya!

Izuku: Actually it's no longer Midoriya my name is now Izuku Wayne.

Everyone was in awe Izuku looked more confident and had gone through a major change. The teachers had smirks on their faces after seeing 2-A's reaction.

Izuku: Great to be back guys hope you all had a great summer.

Before Katsuki was fuming since he was still considered a nobody to the justice league. Now a nuclear bomb was brewing because Izuku had come back a new man who was getting all the attention.

Nezu: Now young Wayne please take your seat

Izuku: Yes sir

Izuku tapped a button on his utility belt that made his costume store itself away within his belt for quicker access. His classmates saw he wasnt in uniform but looked very handsome in his new street clothes

Izuku: Iida before you ask why I'm not in Uniform they no longer fit and principal Nezu allowed me to wear my street clothes today since I'll probably receive my uniform tomorrow or by the end of today.

Iida slowly lowered his hand and said nothing since this is what he was gonna say.

Nezu: Alright class now before we leave you I'd also like to introduce Batman America's number 2 hero who is also quirkless.

Katsuki: What!? Ain't no way some quirkless piece of shit is number 2 in America!

Before anyone could do anything Batwoman was standing infront of Bakugou and grabbed his head slamming it into the desk breaking his nose and causing blood to flow from his face.

Katsuki: You crazy bitch!

Inko at this point was boiling in rage that her quirk evolved and made it possible to lift Katsuki and leave him pinned to the wall.
She slowly removed her mask and Katsuki saw who it was he was shocked.

Katsuki: Aunty Inko?

Inko: Any right you had to call my aunty is gone. Your mother told me I could have taught you this lesson at a younger age but I thought you would change.

She walked back to the rest of the Batfamily and saw a hand raised it was none other than Tokoyami."yes young man" Inko said as she called on him

Tokoyami: Batwoman

Inko: Actually its ms Wayne

Tokoyami: Mrs Wayne were you the original batgirl?

Inko: Yes i was but I hung up the cape when I was pregnant with Izuku.

Nezu: Before you all begin asking more questions the Batfamily is also here to join UA as part of the staff. They've informed that a select few will get trained by them.

The last bit of info surprised everyone the Batfamily were going to train a select few this meant being taught by the best of the best. At this point Katsuki thought he'd still have a shot to join but he threw that chance away already.

Inko noticed that the little girl was still holding onto Izuku while the young boy was talking about how cool his new suit was. Inko walked up to the group of three

Inko: izuku who are the kids?

Izuku: sorry mom the boy is Izumi Kota and he's Mandalays nephews. The girl is Eri shes the one we saved during the Yakuza raid.

Inko had stars in her eyes and it was a look bruce knew too well. It was the look that said lets adopt her so bruce shot a look at Nezu and understood so he'd set something up.

Batman: As Nezu has mentioned we will choose who we will train so we've been given your class roster and tomorrow we will decide who we train.

Nezu: Since this took up most of your class time please head to your dorms. Classes are dismissed for the rest of today. Izuku will you Eri, Aizawa and the Batfamily report to my office.

In Nezu's office

Nezu: So Aizawa how much progress has been made with Eri's quirk control?

Aizawa: she has control over it and she dosen't activate it unknowingly now.

Nezu: Perfect now ms Eri what would you say about being adopted by Izuku's family.

Eri: they look a bit scary

Izuku: Don't worry they're heroes too we make villians think twice about being bad. Guys can you take off the masks and helmet

Izuku: See they're not so scary right Eri.

Eri: Is the lady your Mommy?

Izuku: Yes she is

Eri: She's really pretty.

Inko walker up to the little girl and kelt down hoping she wouldn't be afraid. "Thank you for saying so sweety." Inko said as she petted the girls head then Bruce slowly walked forward and knelt down as well

Bruce: So Eri would you like to join our family? You'll have 4 big brothers

Eri looked scared and unsure until Izuku spoke up "Eri youll be my little sister and you wont have to worry about not seeing me"

Eri: I can have a family

Bruce: You will. So what do you say?

Eri: Can i join your family

Bruce/ Inko: Welcome to the family

Nezu: Congratulations mr and mrs Wayne on adopting your daughter. Eri we hope youre happy with your new family

Eri cried tears of joy then the rest of the Batfamily had gathered around to welcome their new little sister.
