toya couldn't understand why he was like this. why he's so weak compared to his father. he can't comprehend the fact that he's weak to his own quirk. it burns him like it burns others. he hates being this way. he's strong, right? he can do this. no, he will do this. he will surpass all might. just like his father wanted him to.
he's been training nonstop. day and night. on a specific mountain that his father, enji, trained on before. sekoto peak. it didn't matter how early or how late it was in the day. all that mattered was that he was working hard. and making sure he was strong for his father to notice him.
however, everything would be in vain. no matter what, his father hated how he was not immune to his own quirk. due to inheriting your genes, he can't be left unharmed from the flames. he doesn't blame you for that. he can't. you're his mother. he doesn't want to think of you that way. he can't hate you. not ever. even if he wanted to, it's impossible for him.
enji ignored toya. deciding to have more kids for the perfect one. and yet, still nothing. toya cried about it to you. he hates his father. but he loves you; his mother. "i'm sorry i let you down, mom." yes, he's guilty. although he wanted to get stronger for his dad, he also did it for you. he wants to protect you from the dangers of the world. from the abuse of this household by the angry man.
