You're very grateful that you have such a strong and amazing older brother, but he sometimes became too overprotective.

No matter how old you became, he always told you you're too young to become a Demon Slayer. If you really wanted to, you could've gone to the final selection, but you always listened to your older brother. But even if he didn't let you become a slayer, he often trained you so you could protect yourself.

"Please, go to bed." He told you for the third time this night. He just thought you were living your rebellious years.
