Walking down the stairs to the common room the morning after the incident, Izuku is cradling a sleeping Eri in his arms as Ochako had headed out to go pick up some baby formula for Eri to drink. He gets down the stairs and Instantly everyone's eyes are on him and the white haired infant in his arms. Before Izuku gets anytime to say anything he is instantly swarmed by all of Class 1-A including Bakugou trying to see the baby in Izuku's arms. Mineta is the first to speak insulting Izuku loudly causing the baby in his arms to start crying which earns Mineta a smack on the back of the head by Todoroki knocking him out.

"MIDORIYA YOU BASTARD!!! YOU TOOK ONE OF THE BEST LOOKING GIRLS IN THIS CLASS ALL FOR YOURSELF!!!" Mineta shouts waking Eri who begins to cry.

"Shut up!" Todoroki says smacking the grape haired midget in the neck dropping him in one hit. "How'd grape ass even get into this school anyways? Midoriya who's the kid?" Todoroki asks looking at Eri.

"It's Eri, she had a nightmare last night and lost control of her quirk she rewound herself to the age of an infant. By the looks of it I'd say she's about 5 months old." Izuku says rocking her back and forth in his arms slowly trying to get her to calm down.

"Her quirk most likely have activated in response to her trauma, in order to protect herself from the horrific memories she had subconsciously decided to activate her quirk bringing her back to an age where she had no memories thus eliminating the PTSD from the event." Momo says as Eri starts to get fussy from being hungry, "May I try to calm her down Midoriya?" She asks as Izuku hands her to the Creation user.

"Support her head while you're holding her." Izuku says seeing Momo hold the child who looks up at her with curiosity, everyone watches Eri look at Momo before then trying to get at Momo's breasts for sustenance as everyone laughs albeit nervously.

"I believe she is hungry." Momo says handing her back to Izuku, as Ochako comes back from the nurse's office with the required formula for the baby.

"Izu, I have formula for Eri and a number of other things for her." Ochako says before walking up to Izuku and whispering into his ear: "RG told me that I may have to breastfeed her since some babies will refuse to drink formula." to which Izuku gives her a questioning look before she nods and goes to prepare the formula as Izuku checks her diaper.

"Well, it appears that the rules must be changed now that Eri has become an infant. 1st off, we will all get turns to hold her or look after her for a certain amount of time (Minus Mineta). Secondly, Midoriya and Uraraka are not going to be solely responsible for looking after her, feeding her, and changing her as well. We are expected to get along like family and so we're going to act as such to help raise Eri. Lastly, do not try to cut someone else's time with the baby short everyone will get to hold her from time to time." Iida says as Izuku takes the bottle from Ochako and hands it to Eri hoping that she will eat it and thankfully she does.

"Seems fair enough, Who wants to hold her first?" Ochako asks as Todoroki volunteers even though he had walked back to the couch and laid down on it. Ochako walks over to Shouto and hands him Eri to which he sets her on his chest and warms himself slightly to keep her warm and comfortable allowing her to sleep.

"Soooo~ does this mean you two are Official?" Mina tries to tease which causes Izuku to wrap his arm around Ochako's waist and her to kiss him on the cheek.

"Yes, we have been for a little while now actually. Remember when we were attacked at the training camp? Ochako helped me bind up my arms and I said if anything goes wrong that I had to let her know I loved her." Izuku says as Ochako hugs him once again.

"I believe you two should explain what has happened to your parents they would most likely want to meet you two and know that you two are together." Momo says looking Eri whose out cold on top of Shouto who's also asleep now on the couch.

"I was putting off Introducing Ochako to my mom, she will absolutely flip when she meets her and Eri." Izuku says deadpanning knowing his mother will practically have a heart attack at the revelation that she is now a grandmother. "What's worse is that I have yet to meet Ochako's parents and her father probably won't believe what had happened last night with Eri's quirk and think that she's actually our daughter and try to kill me." Izuku mutters getting sweaty and nervous about what Ochako's dad might do to him.

"Well, Mr. Aizawa saw what had happened last night so how about you ask him to vouch for you two and tell your folks that you are telling the truth." Iida recommends as Aizawa himself walks into the room holding a cat in his arms and a cup of coffee.

"Problem child, Uraraka I have already heard what is going on. We'll head over to their homes after today's classes and I will explain everything that happened." Aizawa explains before sipping his coffee and leaving the dorms.

Time Skip:

Classes that afternoon ran by fairly quickly with Izuku and Ochako taking turns having Eri in a baby harness on their chests as they attended their class. During their Heroics class, All Might looked after Eri as the students went on to do another rescue/combat training against each other trying to protect robot civilians and detain the villain team. While they did this, All Might and Midnight played with Eri keeping well entertained until her parents got back from the training. Once the training was over, Aizawa had told Izuku and Ochako to meet him by the entrance and from there they were going to tell their families about their relationship and the situation with Eri. Aizawa chose to go the Midoriya residence first since it was much closer to UA then Ochako's parents were.

Getting to Izuku's apartment the three of them and the infant in the harness on Ochako's chest exit the car and head up to the door leading to Izuku's apartment. Aizawa knocks on the door to Izuku's mother's apartment and within a few minutes Toshinori of all people answers the door. Izuku looks shocked for a second seeing All Might in his door before he invites them inside and tells Inko to come down stairs and that Izuku was there with company as well. As soon as she gets down the staircase, Inko freezes seeing Izuku and Ochako standing there but more importantly seeing Ochako holding an infant girl who is sleeping in her arms. A moment that feels like an eternity passes as Inko stands there saying nothing about the child in Ochako's arms that is until Inko walks over to Ochako and says something that takes everyone off guard.

"Who's the parents of the baby, it's obviously not you and my little Izuku." Inko says causing everyone to breath out a sigh of relief.

"Long story short, she was a 5 year old little girl that we rescued from an Yakuza gang called The Eight Precepts of Death. She had a nightmare that caused her to activate her quirk rewinding her age down to the age of five months." Aizawa says in a dead panned tone. "Principal Nedzu has put her under the care of these two and from what they told me they would like to adopt her as their own." He finishes before Inko picks up the baby studying the features of the child who's sound asleep in her arms.

"Well we came here to tell you that we're adopting Eri and we have started dating a few months ago." Ochako says with a sweet smile on her face seeing Inko smile down at her first grandchild.

"She's so precious! She reminds me of when Izuku was a baby!" Inko says causing Izuku's heart to drop knowing what his mom is going to do next.

"Since you are my little Izu's girlfriend... Want to see Izuku's baby pictures? Oh! Before I forget! When are you two getting married?! When is the second one coming along?!" Inko asks getting really close to Ochako. Izuku wasn't paying attention and was actually looking at Ochako admiring his perfect girlfriend and unconsciously answers his mother's question.

"Probably soon." Izuku responds not realising what he said causing Inko's smile to widen and Ochako's face to turn bright red and her to get a slight nosebleed before Izuku realises what he said.

"Well since we are revealing relationships I think I can trust you two enough to tell the pair of you that I finally said yes to Ms. Joke's advances and we have been together for a couple weeks. She buys me cats and I somehow make her laugh." Aizawa says letting his human side show so that his students don't think that he's just a zombie.

"Izuku? Toshi and I have been together since you all got into the dorms I just never had the chance to tell you that since it's not something I can break over a text. I'm actually quite happy because Toshi told me what you said about him and that you see him as your father." Inko says before handing Izuku his daughter so that she can go get the family album.

"Aww! Zuzu you look so adorable!" Ochako says looking at a picture of baby Izuku in an All Might onesie. "Mrs Midoriya?! Do you have that onesie for Eri? Can we take it please?!" Ochako asks quickly as Inko gets up to go find the onesie in her closet before coming back after a couple minutes with the onesie in hand.

"I kept it and all of Izuku's baby clothes, you can keep looking around the photo album if you'd like I'm going to start preparing dinner for you all. Unfortunately... I lost the only picture I had of Izuku and his father many years ago." Inko says solemnly before heading to prepare their dinner.

Meanwhile...

Inside the Cerberus in the deepest part of the maximum security prison a faceless man sits strapped to a chair in a dark room with beeps from medical equipment periodically breaking the silence. The man manages to get a small photograph out of his pocket from beneath the restraints as to not activate the 4 sentry machine guns in the corners of the room trained on him at all hours. He raises the photograph up so that he may view it leaning his head on his right arm as he reminisces of the times he spent with his family.

"It's funny how fate works... My nemesis chose his successor in my son and I chose my successor in the grandson of my Nemesis's master. If only he knew of his father... my quirk... is his quirk." he narrates to himself in the pitch blackness of his cell.

"To think... I took all that for granted but I will always remember what you look like my little Izuku Yamikumo Midoriya... What a twist of events Indeed." All for One says to himself looking at the black outline of a picture that he can faintly make out with his infrared quirk.
