Shinsou Hitoshi is known to be incredibly clever, usually with a sarcastic edge. He has a way of getting under people's skin when he needs to, for example when using his quirk for hero training. However, he tends to be a lot more flirty when he speaks with you. He's actually really good at reading people, unlike what his expression sometimes suggests. And he can be nice when he needs to be, just tends to be teasing or a tad bit sarcastic about it.
