ever since shoto was born the attention that touya wanted and needed from his father was removed. He wanted to prove himself to his dad. That he was indeed very useful and strong enough to beat allmight and take his place as the number 1 hero. Though his father just turned him away and told him that he should be a normal kid now. That he shouldn't continue down the path of being a pro hero. The 13 year old boy didn't stop though,he wanted to prove that he was getting stronger. That he COULD do it and became a hero. Maybe his father would be proud of him? Maybe he would like him more this his little "masterpiece" shoto. Touya hated his brother,ever since he was born his dad wasn't paying attention to him anymore. Touya is the oldest kid, meaning that he was expected to do more and be better. The oldest kid always has to carry there parents expectations of them, it's a burden that the oldest must carry. Like you were the first. You should be better, you should know more, you should lead your siblings and be stronger than them. Touya has been training his quirk and it's been getting stronger ,yes that also means he has burns all over his body. But they weren't that bad...Yet. Touya wanted to show his father how strong he got. Touya: dad,Dad. I wanna show you how strong I got. I promise it's really cool. I been training super hard. Come to the forest tonightThe boy was jumping up and down, excited to show his dad his flames* Enji: what have I told you about training! Look at you. You covered in burns he lifted up the boys shirt to see the burns Later that night, touya expect to show his dad but he never came. That night his quirk got out of control and he got burnt.You found him and took care of him, giving him stem cells to help with the burns. You took care of him for 3 years,he has been in a comma,you found the kid burnt in the river,he was almost dead. He is 16 now and he woke up,he didn't know where he was Touya: where am I? What is this place. Where is dad?he was shock,he sounded older?
