Izuku walks out of the facility with a heavy weight on his shoulders, he is now All for One whether he likes it or not. The thing that was bugging him about it was the fact that his father had set up every event to make him who he is today. Hisashi blatantly stated that he sent that sludge villain after him which set off a chain of events leading to Izuku becoming the 9th holder of One for All. This begs a new question now, since he discovered that he can eventually gain access to the previous holder's quirks through One for All, will One for All merge with All for One in his own successor? This troubled him greatly, what if the person he chose for the next holder of One for All will give in to the power of All for One? What if he gives into the temptation to get more power? All these questions bounce around the walls of his skull as he walks from the Cerberus to UA taking as long as possible. Then he has a realization, what will his class think of his new power? He is the child of the villain who ended All Might's career, what will they think of him now? Izuku takes a seat on a nearby bench to help him clear his mind from the thousands of 'What if' questions bouncing around his head.

Izuku takes a seat on a nearby bench and as he sits down he exhales heavily and runs his fingers through his hair trying to answer those questions in his head. The world around him starts to distort slightly as a figure in a hero costume comes up to him. It is not the fifth who he talked to during the joint training exercise against class 1-B. This one is a woman with onyx black hair, a beauty mark under her lip, stunning silver eyes and a hairstyle similar to his mother's. This is The Seventh, his grandmother, Nana Shimura. She walks up to Izuku and takes a seat next to him on the bench and places an arm on his shoulder to get his attention. Izuku turns to see her sitting there before she speaks.

"Tell me Izuku, what troubles you so much?" Nana asks rubbing her hand on her grandson's shoulder in a calming fashion. Izuku picks his head up from his hands to look at Nana and recognises her as well as his own mother.

"It's my quirk, What will my friends think? What will the next holder do? Will they become obsessed with the power of All for One? Will I become obsessed with its power? I don't know what to do, all I ever wanted to be was a hero, but now I have an evil quirk." Izuku explains looking at Nana with a worrisome expression. Nana gives Izuku a soft smile knowing smile one of what a mother would give her child.

"There is no such thing as an evil quirk, only evil quirk users. Take the fifth for example, black whip looks menacing and eerie but he was one of the greatest heroes of his time and that was almost 200 years ago. Not all quirks are forged to emanate heroism or evil, it is the user who dictates if their quirk has that trait. Did your mother ever tell you what happened when she manifested her quirk?" Nana asks as Izuku shakes his head no in response.

"When I was told I was quirkless my mother all together stopped using her quirk, the last time she used it was when we were at the doctor's where they told me I was quirkless in the first place. All hers can do is attract small objects to herself... Right?" Izuku answers as Nana nods in understanding.

"No, she has my telekinesis power and she was three when it manifested. We were on our way home with her baby brother in a bucket seat when some would be villain tried to mug us. She was so terrified of the reptile looking villain that her quirk manifested and ended up crushing that villain with a steel I-beam from a construction site we were near. I would have handled it just fine but I had both Inko and your uncle with me so I had to protect them. After that day, Inko hardly ever used her quirk to its fullest potential, she thought it was evil and no matter how many times I told her what I just told you she always thought her quirk was a villain's quirk." Nana explains to Izuku as he nods in understanding.

"Why did you put my mom and uncle up for adoption?"

"We were attacked at home and they tried to kidnap your uncle to get to me, from there I decided that in order to keep them safe I needed to give them up. I wonder what would have happened if I didn't put them up for adoption and just hung up my cape to be a mother. Every part of me hated that I had to do that but it was for their safety and I still love them with all my heart, and that also includes you my little one." Nana replies giving Izuku a kiss on his forehead causing him to smile.

"I still have a question though, Why did you come and not my uncle, the first? And What will happen with the tenth will they become the next All for One?" Izuku asks looking up at his grandmother.

"Shinichi thought that it simply isn't the right time for you to speak with him, and as for the tenth... why don't you see for yourself." Nana says in a cryptic fashion, this peaks Izuku's interest.

His attention is drawn to a shadowy figure approaching him, this figure seems to be around Ochako's height wearing an armored Hero suit. From what he can make out of the costume, it appears to be based off of his own and two others as well. A modified visor over the face and utility belt, bicep high gauntlets, the iron soles and face mask, as well as a long cape. He may not recognize who it is based off the silhouette but a long upward facing horn on the right of the figure's head is a definitive answer in his mind of who is worthy of being the tenth. Then the figure keeps walking past Izuku and the bench before turning into a glowing red star and vanishing. Recognizing who this is a feeling of relief washes over Izuku as he lets out a sigh of relief as a reaction

"You have nothing to worry about Izuku the tenth will be a worthy successor, as for you, you will usher in a new era of world peace with the combined power of One for All and All for One. If you ever want to talk again, you know where to find me. And one last thing before I go, since you have unlocked your full potential, the next step is unlocking the rest of our powers starting with the fifth and now Mine. I'll see you again soon Izu." Nana says standing up from her seat, she gives her grandson a hug before walking off and vanishing into thin air.

"Oi! Deku! FUCKIN WAKE UP!!!" A familiar voice shouts snapping Izuku out of his vision. Izuku snaps back to see Katsuki rearing back to smack him full force to get his attention.

"O-oh, hey Kacchan what's up?"

"Why did you just up and fuck off? It's an hour drive from here to UA and it'll take quite a while longer to walk there from here. Come on we're leaving." Katsuki says motioning for him to follow to Tsukauchi's car and head off back to UA.

Time Skip

"All students come down to the common room, we need to make a couple announcements." All Might says over the intercom of the 1-A dormitory and a few moments later the class files into the common room seeing Izuku and Katsuki standing there next to All Might.

For Izuku, this is probably the most nerve racking thing he has ever experienced, he is about to tell a room full of heroes that he is the son of All for One and is related to the leader of the League of Villains. Katsuki notices this in Izuku and nudges him in the side signifying that whatever happens he has his back. This gives Izuku a sense of relief as he waits for what feels like an eternity for the rest of the class to make it into the room. The last person to enter the room is Ochako followed by Eri who is crawling along next to her Mama. All Might motions for the class to take their seats before they begin. Izuku takes a deep breath before begins to explain what had happened.

"D-do you all remember the villain that All Might fought at Kamino?" Izuku begins visibly nervous about what he is about to say next.

"He is All for One correct? The villain who can steal quirks? What about him?" Todoroki asks as the others just look on in confusion.

"I need to know something first before I tell you this, do you trust me? Do you believe that I want nothing more than to be a hero?" Izuku asks getting nods of confirmation and 'yes' from the rest of the class. "His name is Hisashi Midoriya... He is my father."

"EHHHH?!?!?!?!" The rest of the class shouts in total shock and confusion, it quickly devolves into hundreds of questions being asked at a pace Izuku can't answer all at once.

"Silence!!!" Aizawa shouts quickly shutting up the class. "Now, let him continue. He had no way of knowing his father since he left at a young age and if I hear anything of you lot treating him like a villain you will be expelled on the spot. Do I make myself clear?" Aizawa asks as the students nod and swallow a lump of saliva in their throats.

"He said that I was quirkless to protect me from being bullied for having a villain's power. He was an evil man, and that doesn't mean that I feel anything towards him. Despite the fact I have the power of All for One I am not and will not be my father. I am the hero Deku and I will use the power to take quirks to become a hero taking the powers of villains and giving those powers to those who are not lucky enough to be born with a quirk. Lastly All for One is dead, he had a brain tumor they found in autopsy. Shigaraki is still out there and he is the disciple of All for One he may have the power too and we must bring him to justice." Izuku states showing off his power by causing his hands to glow red and arc with black electricity before shutting off this power.

"It's ok Izuku, we are here for you and we know you're not a villain or ever will be." Ochako says with a smile walking up to Izuku and giving him a hug quickly followed by the rest of the class comforting their friend.

"This gives me an idea, we can do a new battle training. Noumu attacks have been becoming more frequent so you all will have to fight villains with multiple quirks. We have captured several noumus from the attacks all the way between the USJ to what is left of the high end. We will have Young Midoriya steal the quirks from these noumu and you will fight against him to condition yourselves to battle villains possessing several quirks." Nedzu suggests popping up from the capture gear around Aizawa's neck with a cat on his head.

"Yeah! That's a great idea that way I can learn how to use All for One and you all can learn how to better fight Noumu and multi-quirked villains!" Izuku shouts before quickly starting a muttering storm about possible tactics and quirk combinations from the noumu he has fought.

A few days later:

Having not seen Eri in several months due to internships and projects, the big three have finally gotten some time to themselves to go and head over to the dorms to check up on our little snowball. Not only that but a certain little boy has been bugging his aunt to go and see his favorite hero at UA as well. Now both the Wild Wild Pussy cats and The Big Three meet up outside the dorms before knocking on the front door and being let inside by Jirou wearing another one of Kaminari's t-shirts.

"HA! Beat that Shitty hair! How does my entire ass taste!?!" Bakugou gloats/screams at Kirishima having beaten his time on mario kart by almost 90 seconds. Mirio walks straight up to Bakugou and Kirishima and karate chops them on the head for shouting and cursing in front of a kid. What they don't expect is for a crawling baby girl to speed over to Mirio and headbutt him in the leg.

"Hello little one, who are you?" Nejire asks walking over and picking up Eri who giggles after being tickled by Nejire. Ochako walks into the room wearing her harness with a bottle of baby food in hand and freezes seeing Eri in the arms of Nejire.

"N-Nejire-senpai?! What are you doing here?" She asks kinda shocked seeing her close friend in the dorms.

"Oh, we wanted to come by and see Eri and find out how she was. Speaking of, where is she?" Nejire asks as Mirio tickles Eri over Nejire's shoulder.

"Um... Y-you're holding her." Ochako replies as Nejire gives her a confused face before looking to Eri and then back to Ochako and back to Eri again before it clicks.

"What?! How did this happen?! When did this happen?! Why did this happen?!" She shouts holding Eri out in front of her so she can see any resemblance to the little girl Eri that they saved.

"She had a nightmare the night she moved into the dorms, she activated her quirk out of fear and rewound herself to a five month old she is eight months now. We also found out that Izuku and I have to get married to officially adopt her and that he has a new quirk." Ochako explains as the others give her a very confused look, as if on cue Izuku literally flies into the dorms chasing Mineta and Kaminari around the dorms having found out that they snuck into his and Ochako's room and stole a pair of her panties.

"GET BACK HERE DAMMIT!!! THOSE ARE FOR OCHAKO NOT YOUR PLAYTHING!!!" Izuku shouts using a quirk he took from a winged noumu to fly about the dorms chasing Mineta and Kaminari who are twirling around a pair of frilly lingerie that he bought for Ochako.

"Is that his new quirk?" Mirio asks pointing to the large bat like wings protruding from Izuku's back. "He has wings now?"

"No, do you all remember that villain that All Might fought? Apparently Izuku is his son and has his quirk, Nezu has been making us fight Izuku to train us to battle villains with multiple quirks. We have also discovered that he can give the quirks to others as well, there was one exercise that we had to do where Aizawa had Izuku switch up our quirks." Ochako says with a sigh as Mirio motions for Nejire to let him hold little Eri.

"I swear I'll get those two idiots, they stole something I was going to give you as a present Ocha, Oh hey Mirio-senpai! What's up?" Izuku asks as the wings he has retract into his body. "Oh! Kota! How have you been?" Izuku asks walking over to the black haired boy and noticing his red shoes.

"Good, I wanted to come hang out since I haven't seen you in awhile. Whos baby is that?" Kota asks looking at Mirio play with little Eri by holding her up high above his head and bringing her down causing her to laugh hysterically.

"Mine, her name is Eri Midoriya and she is eight months old. Want to hold her?" Izuku asks as they walk over to Mirio and Eri before taking a seat on the couch of the common room with the rest of the visitors. "We actually saved her from a group of villains around 9 months ago but back then she was a girl your age that has a rewind quirk. She had a nightmare and used it on herself and now she is a baby." Izuku explains as Mirio continues to play with eri.

Suddenly, Eri starts to glow a bright golden color emanating from the top right side of her head. Mirio is swallowed by the light before it fades out, where the light originated from is now a small horn like she had before she reversed herself. Mirio on the other hand looks visibly younger and a bit shorter as well. He no longer has facial hair and is now Shouji's height not his normal stature. He blinks his eyes a couple times but notices that he feels something that hasn't been there since the raid on the Yakuza headquarters. Hoping it is what he thinks it is, he quickly hands Eri to Izuku and then activates his quirk that had been assumably erased by the Eight Precepts. His clothes fall off of him causing Jirou to blush profusely as Mirio drops through the floor having gotten his quirk back.

"D-did she just..." Ochako begins looking flabbergasted at what happened.

"She has her quirk!!! Mirio has his quirk back!" Izuku shouts picking up Eri and hugging her causing Eri to grab a fistful of Izuku's hair and start to pull on it. "Ow ow ow ow ow!!!" Izuku says in pain as Eri pulls on his hair.

"This is amazing! I can't believe it's back! My powers are back! Who wants to spar? I'm so out of practice!" Mirio exclaims putting his clothes back on since his quirk made him phase through them.

"Deku? Can i hold her now?" Kota asks motioning to Eri in Izuku's arms.

"Huh? Oh yes sure just be careful with her okay? She can be a little squirmy from time to time especially with people she doesn't recognise." Izuku states handing Eri to Kota, Kota inturn gently holds the baby looking into her eyes as Eri gives him a very confused look. Eri looks at Kota and then to Izuku seeing his red shoes and then back to Kota seeing the same red shoes.

Eri gets quite confused by seeing her dad's shoes on this person she doesn't recognise and it startles her. She starts to get fussy and squirms about in Kota's arms before starting to cry. Before Izuku can grab her and calm her down her horn turns red and puts off some electricity of the same color and illuminating the room in a red light much like she did when she turned herself into a baby. The light fades and Eri is now sitting on Kota's once occupied clothes and in the shirt that is way to big for him is a baby boy. The others look shocked at what happened seeing Kota go from a five year old now down to an eight month old baby like Eri herself. Seeing the other baby in front of her, Eri pats Kota on the face as the two start babbling incoherently at each other. Mandalay looks horrified at what had happened as does the rest of the Pussy Cats, the rest of the students were totally stunned at what happened.

"Uh...Does Deku have to adopt this one too?" Katsuki asks pointing at the two babies playing together on the couch.

"No, I have officially adopted him when his parents were killed so he will still stay with me. I'll make sure he remembers Onee-san. Can he come play with Eri from time to time Midoriya?" Mandalay asks watching the two babies play together.

"I-I don't see why not, beside Eri needs a friend her age anyways. Bring him over anytime you want." Izuku answers as they catch up on the time that has past and celebrate a new beginning for Kota and Mirio.
