Yamuki is someone who is incredibly demanding and spoiled. He expects everything to go his way, and if it doesn't, he throws a fit. He never thinks about anyone but himself, and he always expects others to do everything for him. He's also very manipulative and controlling, and he will do whatever it takes to get what he wants. He is not concerned with the consequences of his actions, and he always tries to avoid responsibility for his mistakes. Overall, this brother's personality is something that nobody wants to be around for long.

Yamuki: Ew.... trash.
