6 Months Later
It's been 6 months since Kitaro met and started training Izuku. Over this time Kitaro had him work out and spar with his clones. Izuku currently looks like he does after his 10 months of training with All Might before U.A. in canon.
Izuku also helped make different moves for everyone. While Izuku can now land a solid enough hit on his clones to make it dispel. Kitaro's clones only had enough chakra to fight off a low level villain. Although Izuku hasn't had much trouble from Kaksuki since the day Kitaro threatened him in front of his entire school.
Start Flashback
2 weeks after meeting Izuku, Kitaro wanted to go see if he wanted to come over to train since his school let out early. He had the girls go ahead of him. Once he arrived at Izuku's school he arrived just in time to see Izuku walking out of the front door. No less than a second later Kaksuki came around the corner and hit him with a explosion in the stomach.
When Kitaro seen Izuku get hit by Kaksuki, he ran so fast that before Izuku hit the ground Kitaro spin kicked Kaksuki right in the nose. Everyone around them was surprised to see Izuku be defended but what shocked them most was that someone hit Kaksuki.
Once Kitaro landed back on the ground he asked while sticking his hand out for Izuku to get up "You alright? I'm not sure what that guys issue is but he needs to get that ego of his in check."
Izuku could only accept the offered help while saying "Y-yes I'm fine. I just didn't see it coming is all, and kaccan has always been like this." He finished with a sad smile.
Kitaro only shook his head and was about to reply when he heard Kaksuki say "It's you again. Don't think I'll just let you get away with kicking me, you damn extra."
Kitaro looked at him with amusement plain on his face then said "Let me get away? I'm sorry, I must have missed heard the explosive pomeranian. Last I check you and your two lackeys ran away with your tails between your legs."
A crowd gathered when Kaksuki was first kicked, but now more kids joined around them. After hearing Kitaro's mocking word and the amusement mixed with pity on his face made most of them start laughing.
Kaksuki was already mad when he was kicked away, then became angry hearing what Kitaro said, but what made him launch straight for Kitaro was the laughing of the others.
Trying to hit Kitaro with a over hand explosion failed when he was kicked in the face again. Only this time Kitaro made sure he left a footprint where he kicked him. Getting back up Kaksuki heard the laughter and seen phones recording. It made him so mad he started to fight blindly.
Kitaro only wanted to put the mutt in his place but after the fifth kicked to the face he got bored. Kaksuki was about to get up from the last kick when Kitaro appeared right in front of him bringing his knee straight to his face aimed for his nose. Dislocating it, right before he fell unconscious he heard Kitaro say "Put your hands on my little brother again, and I'll beat you so bad you won't be able to be a hero."
After his words with Kaksuki Kitaro walked off with Izuku with everyone making a path for the two. Nobody was able to look at either since they all knew how they treated Izuku, and if that's what his brother did to the so called strongest of their school, what would've happened to them.
End Flashback
Kitaro was now on his way home from the store since he wanted to get things for the girls. While walking he heard what sounded like a fight in the alley. Going in he made his way to the fight while picking up 5 stones small enough to all fit in one hand. When he arrived he seen someone being held by the throat but what looks like a human - rhino.
( Aizawa POV )
It was 8 in the morning when I got a call from one of the pro heroes I usually help out. Asking for my help in taking down a new drug gang tho they might not be selling trigger, what they have is just as bad.
I met them around 9:30 to talk about all the information they had, while I would be handling the goons in the warehouse the other hero will be going to where they keep their stash house.
It was around 7 when we started the mission. As soon as I kicked in the door I activated my quirk canceling their own. I wrapped my binding scarf around the neck of the closest thug and throw him at the table where the other two were just sitting. One recognized me and told his partners however before they could act. I kicked a chair at one of their heads knocking him out since he hit the wall behind him.
Then I focused on the last two throwing my scarf at the one who aimed a gun at me. I made it so he'd pistol whip the one next to him right as his head turned I had him slam the gun right in his face.
Once both were stunned from the pain, I ran to them while kicking one in the face, I slammed the other one with the gun face in the ground knocking him out.
After I put the quirk canceling cuffs on them then I turned mines off. It was only instinct that save me from being crushed against a wall. Right as I jumped out the way a human - rhino crashed through the wall I was standing by.
Seeing this I prepared to fight since I already called for clean up a few heroes should also be arriving. Just not soon enough since after trying to crush me the rhino decided it'd be better to break my bones. He already got my left arm pretty good trying to block his punch, and at least 3 maybe 4 cracked ribs.
After throwing me out the building we ended up in a alley when I tried to get up the rhino grabbed me with one hand by the neck. He then told me he was going to enjoy breaking every bone in my body starting with my legs so I can't run.
I must say at least he was some what smarter than the everyday villain. He probably didn't know I had back up on the way I just hoped they bring someone with some firepower to help.
Then the next thing I seen was two stones hit the rhino in the head and the arm holding me up. I turn and see a kid no older than 13 maybe 14 with red hair with black mixed in, 10 tails, fox ears and a sleeping 9 tailed fox on his shoulders.
( End POV )
Kitarodidn'twaste time channeling chakra in two of the stones in his hand forcing the rhino to drop the man he was choking and face him. Kitaro looked calmly at the villain and asked "You know, choking people in the back of alley is kinda frowned upon. I suggest you leave before I call the cops."
After saying that Kitaro looked at the man he just saved. It only took him 3 seconds to recognize him and another two for him to realize what was really going on.
Aizawa said "Kid run away from here and just call the cops."
After hearing what Aizawa said Kitaro replied saying "I'd love to but I don't think he'll just let me run off." Pointing at the rhino man who was starting to charge him.
Kitaro seeing that the rhino man was getting closer he threw the last three stones with chakra at his head knocking him out.
After making sure he was completely unconscious he used earth binding jutsu on him to insure he can't escape. He then walked up to Aizawa saying "Sorry for interfering with hero business Eraser Head I didn't recognize you at first and well I heard someone in trouble. As for you, your arm is broke along with having 2 cracked ribs. Bite my arm it'll help heal your wounds."
While checking over his injuries, he stuck out his arm to heal him. Aizawa looked at Kitaro for a long moment after hearing what he said. Seeing he was being completely serious he gave a sigh and bit his arm only for most his injuries to be healed. Just a bit of pain where he was hurt.
Aizawa then said "Thanks for your help kid but you do know what you did is technically illegal and I should be arresting you yes?"
Kitaro look at him then shrugged. Saying "Hey if you gotta arrest me that's fine even if you weren't a hero I would have helped you out."
Aizawa then asked "Speaking of how'd you recognize me? I'm not that famous and I don't like the media." He finished with a suspicious look in his eyes.
Kitaro replied saying "Oh that's easy, I can appreciate the type of hero you and most underground heroes are so I keep track of almost all of them. I hate the media as well they're nothing but vultures."
Aizawa just looked at him for a second then said "I can agree on the last part. However I won't be able to just let you go since he broke the last pair of cuffs and I won't be able to explain that." Pointing at the rhino man who's arms and legs were trapped by earth.
Kitaro was about to reply when he heard a few people running to them. Seeing that it was the police and Present Mic.
The police took Aizawa's statement about the incident making sure they knew he would be dead if Kitaro didn't step in. They brought Kitaro to the police station just to get his statements and insure he was fine.
Once arriving at the police station the officer took Kitaro to one of the break rooms since he wasn't in any trouble. They did tell him that they called his mother making Kitaro go pale in the face. With him thinking "Shit, I'm a dead man I knew I forgot something. If mom doesn't kill me the girls definitely will." Kitaro gave a shiver of fear thinking "Fuck, there is no way Haku doesn't find out and skin my ass alive."
Kurama who could hear his thoughts couldn't help the chuckle at his expense.
Kitaro told the officer it was fine while waiting for the detective. After 5 minutes of waiting a man in a suit with a trenchcoat came in the room and sat across from Kitaro. Pulling out a pen and notebook the detective said "Hello young Uchiha, my name is Naomasa Tsukauchi. I'd first like to thank you for your help in saving Eraser Head, he told us if you didn't arrive in time he'd be dead or at the very least he'd have to retire as a hero. So thank you again."
Kitaro just replied saying "It's not a problem. I heard what sounded like a fight and decided to see what was going on. I just didn't expect to be saving a hero."
Detective Naomasa then said "I see, well can you tell me what happened from the beginning until the police arrived?"
Kitaro proceeded to tell him how he was going home from getting gifts for his girls when he heard the fight. Then decided to investigate, he then proceeded to describe the short fight he had. Then making sure the villain couldn't escape, he healed Aizawa.
Once the detective finished taking notes he said "Thank you once again for your assistances today Eraser Head is a rather important hero even though he hates the attention. Now then if I may asks what is your quirk since when I looked at your file it say you have 3 different quirks. I guess I'm asking which quirk lets you manipulate the earth the way you did?"
Kitaro replied saying "Oh it's my chakra it allows me to do a lot but if we can keep this between the two of us I don't mind telling. The energy in my body allows me to completely control the 5 main elements. Fire, water, lighting, air, and earth I've been working on adding two different elements to control sub-elements but it's been slow progress."
Naomasa was surprised to hear how strong his quirk was before he could reply however Momo, Haku, Saiko, Nejire, Toru, Yui, and Seki came in with the girls running to Kitaro.
Even though the girls know how strong he is they still worry for him. Since they do love him. Once they made sure he wasn't hurt the girls looked at each other then nodded in agreement. As one each of them punch the top of his head making him hit his head on the table with Momo saying "Do you know how worried you made us? You said you'd be back in 30 minutes only for the police to call us saying that you saved a hero." She finished with a glare.
Naomasa was watching the scene with amusement before clearing his throat saying "Hello Ms. Yaoyorozu thank you for coming. Kitaro here just finished giving his statement so he can leave at anytime. He's not in any trouble either so he's free to go."
Seki replied saying "Thank you detective. I'll be taking him home then, I'm sure he'd rather be yelled at by the girls there then here." She finished with a small laugh at the end.
Once they got home the girls yelled at Kitaro for 20 minutes before they were satisfied. After they made him cuddle them the whole night while watching movies.
The next day Kitaro can be seen training in the backyard when Seki came looking for him with Eraser Head and Principal Nezu.
Kitaro was currently blindfolded with a katana shirtless against 20 clones with real kunai. Aizawa and Nezu were able to see him dispel the last 5 clones with little effort while blind.
Taking off the blindfold Kitaro looked over to where he sensed his mother and two guests walking to him. Grabbing his towel and water he made his way to them.
Once he arrived he said "Hello mother I see we have company." He then turned to the two hero's saying " Hello Eraser Head, Principal Nezu what can I do for you today?"
Aizawa replied saying "Nothing much, my boss just wouldn't stop nagging me until I agreed to bring him to meet you."
Nezu gave a laugh saying "Ignore him. The lack of sleep is getting to him I tell you. No I wanted to come a personally thank you for saving my right hand."
Kitaro not wanting to stand decided to make a table and chairs for the pair under some shade. While having a clone bring a chess board, and tea outside.
Once he took a seat he said " Please, please have a seat I have a clone bringing tea. Would you care for a game of chess while we speak? I do love new opponents."
Nezu's eyes light up saying "I would love to play a game. It's been awhile since I last got to enjoy a good match."
Kitaro and Nezu played 5 games total with Nezu taking the final win. While playing Nezu offered Kitaro the chance to fight with Aizawa 3 times a week while 3 days will be set aside for training with Nezu on strategy and tactics.
Kitaro of course new Nezu just wanted to keep an eye on him but he didn't care since it wasn't like he was going to destroy the world if anything he wants to rule it.
