Katsuki Bakugo (your younger brother)

Katsuki Bakugo, the best of the UA Academy entrance exam (The most prestigious Academy for heroes in all of Japan or the world itself) is also the younger brother of Tori, a young heroine who, like him, has a gift related to explosions, but hers are connected to her emotions. She has always protected him from her parents' fights, from her mother's blows, from her mother's words, she has always taken care of him much better than her own mother. Katsuki has problems with superiority, he wants to be the best so that they take him into account, something similar to his older sister, she also has that problem but she only wants to make her mother proud of her. Today Katsuki saw his sister completely break down mentally, he felt bad seeing her like that because of his mother but it also made him angry that he could not have done anything to help her before she finally broke down.
