Martial Arts Dojo [1]
On the four years that passed, both Yuki and Shoto grew considerably and both of them learned how to control their own quirks in precise ways, they were also traumatized by their training and swore that they would never piss their mother off, no matter what.
Her training broke them even more than Enji training, they were forced to endure different levels of temperature, it was easier to Shoto due to his half-cold-half-hot quirk, however, Yuki had to endure low levels of temperature, sometimes almost freezing, not to mention the burning sensation of the Ice on his body, he had to endure it to get stronger.
Of course, this suffering was only on the start, Yuki body adapted to the temperatures after time passed and it also helped to temper his body, pushing it directly to Chunin level after the four years of tortu- training.
This doesn't mean that he neglected his chakra training, it was the opposite, after the daily training was finished, he trained chakra control, his chakra reserves didn't increase by many times but it grew from Elite Genin to Chunin, being on equals ground with his Taijutsu, he also made sure to master the 'Body Flicker Technique' without the need to use hand seals because it would be useful in a fight.
Yuki learned how to use Chidori but can't use it many times, only two times a day, his Sharingan, unfortunately, hadn't evolved to two-tomoes but he isn't sad, he has, literally, infinite time to evolve it.
Spotting his brother, Yuki approached him and asked ''Touya-nii-san, mother said that she would give us a surprise, do you know what it is?''
Touya smiled lightly before he said ''These four years, both you and Shoto learned how to control your quirk and trained your body, think, what lacks?''
The white-haired boy started to think before he quickly came to a conclusion, he and his younger twin brother had trained their body and already knew how to control their quirk almost perfectly, which means that the only thing lacking is their way of fighting, sure, with their quirk, they could fight and win minor villains, however, if a villain knew how to fight, they would be doomed.
Martial Arts - This is exactly what was lacking for the twins, Yuki felt happy after discovering what the surprise would be, his mother would put them at a Martial Arts Dojo, probably!
''Hn. Thanks, Touya-nii-san!'' Yuki thanked his brother, hugged him and went to meet with his younger, twin brother.
Touya sighed, seeing how happy his sibling was acting and shook his head, he had to study for the tests at U.A High School, he slept late last night and the test is tomorrow, sighing once again, he entered his son and focused on studying.
Yuki entered another of the many courtyards at the place his family lives at and saw his mother and Shoto, Rei was training Shoto in controlling his quirk, his control was much worse compared to his older, twin brother, that had practically perfect control.
''Oh, Yuki, you finally arrived here, hm? I was thinking that you would let me wait for an eternity!'' Rei said with a slightly annoyed tone and Yuki started to sweat before thinking of a solution and quickly hugged his mother ''Well, since you're so sorry, I'll pardon you this time!''
Yuki instantly knew he was tricked and that his mother just wanted a hug 'Damn...' he thought to himself but showed none of it on his expression ''Mother, you said you would give us a surprise, can you tell us about it, please?'' Yuki asked, wanting to confirm if the surprise was what he's thinking.
''Yes, I'll tell both of you about the surprise, I don't know if both of you remember that we're friends of the Yaoyorozu family, right? They came here often when you two were four years old!'' Their mother said with a small smile, Shoto immediately replied
''Oh, I remember Uncle and Aunty, they created many cool things for us!'' Hearing this, Yuki nodded in agreement, they once created a small, ice igloo for him, it was one of the few toys he liked.
Though he didn't have any real experience, as a reincarnated person, he was much mature compared to kids of his age, paying close attention, Yuki heard his mother saying ''Well, well, you two probably don't know but they're known as the 'Creation Couple' because their quirks complement each other, they were the Top Four and Five heroes, now they're the Top Three and Four respectively, since I retired!''
Shoto, as usual, had sparkles around him as he said ''Really? I never thought that Uncle and Aunty were so strong, they're amazing!''
Yuki also nodded, feeling surprised that the Yaoyorozu couple were so strong but before he could say anything, Rei said ''They recently opened a Martial Arts Dojo and it is very famous, Ikki is one of the best Martial Artist of our entire country, which is why I want both of you to be a student at their Dojo!''
''I see..'' Yuki agreed with what his mother said.
"Well, tomorrow you will start your lessons, get to know that they only accept children of 8 years old or more, and Yuki, they have a daughter of your age, good luck!" Before Yuki or Shoto could react, Rei vanished from the spot, she ran with success.
Shoto was excited that he would be able to get many friends, they were homeschooled and because of that, they didn't have friends because of that, as for Yuki, he was wondering why his mother said that, he didn't have any experience before except that he's more mature than kids of his age.
Nonetheless, he was still excited about being able to be a student of the Yaoyorozu Dojo, he would get stronger, after all!
