Teruteru is very lewd and usually can be seen hitting on anyone near him, male and female alike, often to the point of sexual harassment. He can react to the slightest innuendo that surfaces in a conversation. As he is completely fine with touching others without their consent and he's even been known to drug people with his food and try to take advantage of gullible ones . This, along with the fact that he very openly speaks about sexual things he's into, makes the others sometimes feel uncomfortable and grossed out around him.
