Preparations for the Future.

[A few weeks after the battle]

[Kaito POV]

Since that day I haven't stopped training, a few weeks ago I confirmed that it was the day when All Might would fight All for One and win at the cost of losing more power the more time he spends in his buffed form.

The shockwaves were disguised as an earthquake and most fans believe that All Might got hurt fighting Toxic Chainsaw, but I knew the moments I felt the first clash that it was OFA VS AFO.

I was scared, for the first time my hands were shivering but not from excitement but from fear of facing such power. My resolve became stronger so every day after school I went to train at the outskirts and perfected as many techniques as I could.

[Third Person POV]

"Sound Breathing First Form: ROAR!" Kaito lifts his twin swords above his head and slams them down with great force, causing a loud sound resembling thunder as a result.

The ground breaks and Kaito loses balance and falls down accidentally stabbing his leg instead of the floor.

Kaito took out the sword and started to heal his injury with a first-aid kit. After the bleeding stopped, he continued training even though his leg hurt like hell.

'Why can't I use it yet, if I have his physique then why can't I use sun breathing?' (Note: Should I refer to it as Sun Breathing or Hinokami Kagura?) Kaito asked at himself. Despite having Yoriichi's physique there is a specific reason why he cannot use it, said reason he will discover in the future but for now this inability infuriated him.

'Does this mean that I don't have what it takes to become stronger? NO! I refuse that logic, I will train harder and harder to surpass my limits, even if I can't achieve Sun Breathing, I will overcome and perfect everything else' Kaito thought and got back to training.

It was 10:00 PM and Kaito was tired from overtraining, but hi lift himself up and walked home, back at home he took a shower ate and went to bed, since he was so tired, he forgot that Kaia was observing him and became concerned about her son's well-being so she decided to follow him tomorrow.

Kaito was so focused at training and getting stronger that he didn't even notice his mother sneaking behind him, once in the training ground he went full hardcore mode on himself and left his mother speechless.

From seeing Kaito's body scars to seeing him crashing and cutting himself Kaia had enough and yelled at him.

"KOBAYASHI KAITO!" needless to say she was angry.

Kaito snapped and saw his mother glaring at him and so he gulped trying to come to an answer but before he could explain himself his mother smacked him in the head, it was the first time that Kaia ever hit Kaito so this took him by surprise.

"What do you think you are doing! Do you have any idea how worried I am by seeing you in such state, you've been doing this for days and had told me that you are fine and I trusted you but now, look at how your body is!" Kaia yelled at him.

"I have to try this hard mother, I don't have any choice, there are villains out there with strength that goes beyond our wildest dreams and to overcome them I have to go through a harder path, if I have to do that then so be it!" Kaito yelled but Kaia smacked him again.

"I don't care as your mother it is my duty to protect you as long as I can, even if its from yourself, you once told me that I shouldn't carry everything by myself so of course I won't let you do the same!" Kaia said with tears on her eyes.

Kaito looked at his mother and felt a sense of disgust towards himself, he was being a hypocrite he chose this path to prove a point, he could've been a vigilante but chose to be a hero instead, he was already aware of the ridiculous power levels that he has to overcome in the future and that rushing things would only damage his body.

Kaito felt ashamed of sharing the same body as Yoriichi, from the many characters in Manga Kaito or more specifically Watanabe Kai idolized Yoriichi not only for his strength but for his morals and attitude towards life, he subconsciously knew that what he was doing was self-destructive but kept going because he felt like he had something to prove to himself.

"Sun Breathing" was the only thing he could think to master but now he felt like he wasn't even worthy of using it.

Seeing his son's darkened expression Kaia asked Kaito "is something wrong son? Did I smack you too hard?"

Kaito dropped tears and explained the same story of the old man. (He loves his mom but he's not going to tell anyone about being a reincarnation) He expressed his deepest thoughts about not being able to overcome said weakness and letting that man down.

Kaia was at ease that her son told her everything, she was scared that Kaito didn't trusted her but she now saw that he only had the intention to not worry her.

After calming down she told Kaito "I think it's wonderful that you were held in such high esteem but, remember that man and remember that he couldn't do everything by himself, if he relied on others to continue for him you can do the same and if you are not strong enough just take your time to reach your goal, even if that man was strong since birth he still trained patiently to be what he became, so don't rush it hone your skills one step at a time and never forget that" Kaia said while patting Kaito's head and then hugged him.

"I trust that you will find your answer, I'll see you at home, I love you" Kaia said while hugging him and then left.

Kaito's mind was a mess he felt that what his mother told him was correct, and that he needed to remember who he is now, he's not Watanabe Kai, neither is he Yoriichi Tsugikuni, he is Kobayashi Kaito, the person that will become the #1 hero.

"Total Concentration: Sun Breathing: Dance" Kaito preformed a singular downwards vertical slash in an arcing motion, leaving traces of heat in the air.

Realizing this Kaito's eyes gleamed with light, like a moth to the flame he went and continued practicing the total concentration breathing and Sun Breathing for another hour.

After the adrenaline faded, he was exhausted, he couldn't keep up and fell on the ground while seeing the clear blue sky turning from blue to orange. 'It's beautiful' thought Kaito, he always rushed in everything so he never noticed the little things in life like this.

The calm wind the bright sun posing itself down, the heat of his body leaving him, before long Kaito fell asleep, just when he was snoring Kaia appeared with a basket of food for him.

'Looks like you got the answers you wanted' Kaia said after looking at Kaito's smile 'I think I also have to be braver and tell you everything but, will you despise me? Blame me? I don't want you to see me differently, how much you could hate the old me, alas I'll tell you at your 15th birthday so please don't hate me too much'.

Kaia put a blanket on Kaito and waited for him to wake up.

After 2 hours of sleep, Kaito woke up and saw his mother besides him.

"Good-morning" Kaito said.

"Son you should stop falling asleep in weird places" Kaia said teasing him.

"So how did it go"

"Good enough, I don't have to rush so much" Kaito said with a smile.

"I am relieved I thought I had to smack you another 5 times for you to understand" Kaia said concerned.

"Heh heh I won't do it again mom" Kaito said shily.

"Eat first then take a shower and then rest, your body needs time to cure those wounds" Kaia said in a menacing tone.

"O…ok" said Kaito sweating.

Kaito realized, the Sun Breathing has more to it, a calm mind and heart with an unbreakable resolve are what allow someone to use the technique, both Yoriichi and Tanjiro hated Muzan but despite that their hearts and minds were calm so all this time Kaito's inability to use Sun Breathing was because of his wavering heart and mind about not being worthy.

Kaito went home and rested, there was not much that he could do, his mother was right he has to take little steps to grow better, it was never about raw power all demon slayers perfected their techniques to the utmost limits and that's what made them strong. Feeling tired Kaito fell asleep and dreamt about the techniques he has seen in the manga and anime, inspiring to create new forms and implement some more to his arsenal.
