Tamaki's father: Tamaki, you put too much power into your throat strikes. It's as if you were delivering a lethal blow against a villain. You should not be even be using throat strikes.
Tamaki: I can't use them on anyone?
Tamaki's father: Well, perhaps if you were fighting an older man, only if he's experienced in the ways of kendo, and you are at least in high school. Until then, it is off limits.
Tamaki: (thinking) He's a man. He's older. And he has kendo experience...Father, Mother, I'm in high school now. It's allowed.
