6 Months Later
It's been 15 years since Kitaro was reborn. After his meeting with Nezu and Aizawa Kitaro spent 2 weeks of every month to train with them. While training Kitaro taught Aizawa how to use moon and snake breathing styles so he can have a better fight with him.
It was a Friday afternoon Kitaro was walking home from training with Nezu. When all of a sudden Kurama and Kitaro sensed an overwhelming amount of fear and dread. Kitaro stopped walking with Kurama sayin "Kitaro did you feel that?"
Kitaro said "Yes. Help me find where its coming from." After sayin he and Kurama rushed to were he felt the fear with his Sharingan activated.
Kitaro arrived in a body flicker in front of a alley way seeing a little girl running away from a man with a bird mask looking behind herself. Kitaro crouched down to a knee to catch the little girl in his arms.
He took a second to take a look at her she had on a hospital gown, with bandages around both her arms and legs. She had a small horn on the top of her head with pale blue gray hair, red eyes and was 3 feet tall.
He then recognized her as Eri just three years younger than canon Eri. As soon as she was in his arms she looked at him and whispered "Help me please."
Seeing the fear and desperation in her eyes. Kitaro replied saying "Don't worry little one, you're safe now." While hugging her closer to himself.
That's when the man chasing her said "Eri get back here, the boss will get mad if you don't."
Eri only held on to Kitaro even more. Saying "Please. Please don't let him take me back."
That's when the man seen Eri in Kitaro's arms slowing down saying "Hand over the girl brat this is none of your business. Don't make me have to teach you your place."
Kitaro hearing this just glared at him while his Sharingan transformed to his Eternal Mangekyo Sharingan he then said "Tsukuyomi."
The next thing the man seen was a blood red world. When all of a sudden chains lashed out at him. Chaining him to the ground trying to break out of the chains he seen the same kid from before.
He then said "What the hell is this place? What did you do to me brat? You think you'll get away with this? Overhaul will kill you and your whole family when I tell him about this." He finished yelling in anger.
Kitaro just looked at him with a tilt of his head as he replied saying "Who said you would be telling anyone anything? You'll be lucky to even be able to speak after I'm done with you. Tell me why was the little girl covered in bandages?"
The man just said "Fuck you brat, you honestly believe I'll tell you a thing?"
Kitaro only gave a cruel smile while saying "Oh no. Not at all, well not at first, but you see I'm God here time in this world works differently from outside 72 hours in here is only one second outside. I'm curious just how long you'll be able to hold out before telling me everything I want to know."
After saying that a sword appeared in his hands and he stabbed it slowly in to his chest, while twisting the blade. Then five more clones appeared doing the same thing. Making the man scream in pain. He then passed out from the pain. The next thing he saw was the same kid with the cycle repeating over and over again.
Kitaro then said "You have 71 hours 59 minutes and 59 seconds left. Do you really believe not giving me my answers will make me stop? Well it doesn't matter I'll just up the pain." After sayin that copies of the man could be seen all around the area tied to a cross now with their arms and legs nailed to them.
Kitaro then had hundreds of clones stab, burn, drown, and blasted him with electricity. After a while he told Kitaro that his boss Overhaul was experimenting on the little girl because of her quirk. Killing her then reviving her to make quirk erasing bullets. However they only made 5 permanent quirk erasing bullets since Overhaul just found out how to make them.
Kitaro hearing this only got mad and with a cruel smile said "Thank you for the information you have been very useful. However that fact you tried to taking her back there, I'm going to completely shatter you mind, you'll be lucky to think straight when I'm done with you." He then proceeded to torture him till his mind shattered.
He then closed his eyes and turned off his Sharingan. Looking down at Eri he said softly "You're safe now little one can you tell me your name?"
Eri looked up at him and seen his pretty crimson red eyes were gone changed to a pair of sapphire blue. She then said in a small voice "My name is Eri. What happened to your pretty red eyes Mister?
Kitaro smiled at her saying "It's nice to meet you Eri. My name is Kitaro Uchiha and you liked my pretty red eyes. It's apart of my quirk I can change the color of my eyes." While reactivating his Sharingan to the Eternal Mangekyo Sharingan to his Rinnegan.
After changing his eyes back to normal he asked "Now can you tell me what happened and where you're parents are?"
Eri only started to cry a little saying "Momma left me 2 months ago to the mean bird man and I never had a poppa." She finished looking down at the end with a few tears falling on the floor.
Kitaro then said "Well how bout you stay with me then? I'll protect you from that mean bird man from now on."
Eri looked up with hope in her eyes for the first time in months with tears of joy in her eyes. Then hugged Kitaro while nodding her head in to his chest.
Kitaro used medical ninjutsu to run a check up on her to make sure she was healthy. Other than the few scars on her arms and legs she was completely fine.
After making sure she was fine he looked over at the body laying on the ground then burned it with the flames of Amaterasu. Insuring the flames didn't spread he put out them black fire. Then picked Eri up while carring her in his arms he noticed Kurama looking at her.
Kurama looked at her then said "It's nice to meet you child, I'm Kurama The Nine Tailed Fox."
Eri looked at the him in surprise and said "It's nice to meet you too mister Kurama I'm Eri. Is it okay if I pet your tails?"
Kurama only replied by moving to Kitaro's shoulders where Eri was and wrapped his tails around her. On the way back home Kitaro decided to run on the rooftops to get home sooner while calling Nezu.
As soon as Nezu picked up he said "Am I a dog, a bear, who knows but I am the principal of UA. This is Nezu speaking how are you doing young Kitaro? You just left you didn't leave anything behind did you?"
Kitaro replied saying "Not at all principal I just need your help with something that's all, see I may have just saved a little girl from Overhaul. The girls mother give her to him and he may or may not be making quirk erasing bullets. Can you meet me at my house with Aizawa and Recovery Girl? I don't want to take her to any hospital."
Nezu paused then said "I'll be at your house in 20 minutes and we can talk about what will happen next."
Kitaro replied saying "Thanks principal I'll see you soon." He then hung up and ran off to his house.
Once arriving Seki was sitting in the living room with Momo, Haku, Yui, Toru, Saiko, and Nejire. Haku was the first to seen him and what he was carrying leaving her mouth completely open in shock. The rest of the girls turned only to have the same reaction.
Momo then said "Kitaro why do you have a little girl who can't be older than 4 with you?"
Haku replied saying "Yea and why is she covered in bandages?" After saying that everyone was about to get up to surround him but he stopped them by saying " Wait she might not appreciate being surrounded right now. Can we wait til Nezu gets here to explain everything? In the mean time mother is it alright if we adopt Eri here, her mother abandoned her in the hands of Overhaul."
Eri looked up at him and asked "Are you gonna be my new poppa from now on?"
Kitaro paused in surprise then said "Well you can think of me as a big brother okay?"
Eri only shook her head while saying "No, you saved me from the bad man so you're my poppa."
Seki gave a small giggle. Then covered her mouth with one hand and said "Oh that's a wonderful idea. Kitaro you know I've always wanted grandkids, and now you just brought me home a adorable little unicorn as a granddaughter."
Saiko gave a laugh while saying "Oh yes I think that's a fantastic idea, don't you girls think so too?"
The girls all gave a small laugh and instantly agreed, after 15 minutes of waiting Nezu arrived with Aizawa and Recovery Girl.
Aizawa walked in the living room with Nezu on his shoulder and Recovery Girl following behind her. Nezu was the first to greet them saying "Hello young Uchiha. I understand that you found a little girl who is in need of help?"
Kitaro replied saying "Yea, Eri here needs a proper check up. Since I'm not skilled enough to be sure she doesn't need anything else."
After a while Recovery Girl came back with Eri and told everyone that she was fine just needed to eat properly and she should make a full recovery.
Then Kitaro told Nezu and Aizawa what happened. After getting the full story Nezu spoke saying "Well I'm glad you were able to save this young girl and getting us this information. If I'm not mistaken Sir Nighteye should be looking in to Overhaul. If what you said about him having permanent quirk erasing bullets made from this young girls quirk, then you did the right thing taking her with you."
Kitaro gave a nod saying "That's good to hear, since I would have taken her even if it was Overhaul himself trying to take her back."
Nezu smiled then said "I'll help make it so you can adopt her within a few days at most. For now I know you guys plan on joining U.A. will you be wanting her to join you during your classes?"
Kitaro replied saying "Yes, I want her to stay with me for now I'll make sure she's taken care of. For now though she'll need to get used to being around others."
After they finished discussing about Eri Nezu asked "Kitaro will you be accepting my recommendation for the test, or were you planning to take the public exam?"
Kitaro smirked saying "Come now Principal Nezu, you should know me better than that I want to break records so I'll be taking the public exam."
Aizawa replied saying "If that's the case then I'll be sure too be harsh while grading your tests. Since I'll be expecting more from you."
Kitaro let out a small laugh then said "I'll keep that in mind Mr. Aizawa. If I'm being honest I hoping that the test will give me the chance to have a good dance."
Aizawa rolled his eyes and gave a sigh. Then got up with Nezu and Recovery Girl leaving the Yaoyorozu mansion.
After the three left, Kitaro took Eri with him to get her something to eat while the girls went to get her some clothes to change her out of the hospital gown.
Over the next few days Kitaro took Eri to the mall with the girls to get her new clothes that she'd liked, along with everything she would need for her education.
It was a Saturday afternoon when Kitaro decided to help Eri train her quirk so she doesn't have a random out burst of her powers. The two can be seen sitting outside across from each other with a lot of old junk around them.
Kitaro then started speaking saying "Eri I'm gonna help teach you how to use your quirk that way you don't need to worry about having a random out burst of power. You don't need to worry about anything I'll be here to help guide you through everything." He finished softly at the end seeing her hesitation and fear.
Eri gave a hesitant nod saying "If you're sure poppa, I'll trust you."
Kitaro gave her a smile and they began training. It was over 45 minutes before Eri started gaining control over her quirk. Once she started gaining control over her quirk she gain confidence in using her powers.
After a hour and a half of training Eri Kitaro stopped her since she was starting to get tired saying "Alright Eri, that's enough for today. I don't want you to over do it now we can continue tomorrow, for now let's get some rest shall we?" He finished with a smile at the end.
Eri gave a smile then ran in to Kitaro's arms crashing into his chest. He picked her up then carried her inside after having the girls change her they had dinner and went to sleep.
