Quecchon (クエッチョン, Kuecchon) is a member of the Quiz Society together with Enigman.
Like Enigman, Quecchon's personality changes when she removes her mask. With it, she has a gentle and obedient personality and dearly loves Enigman, but without it, she has a rude and cruel personality and couldn't care less about him. But even if she removes her mask, she's still a nazochist (people with passion to gives a hint from a question).
However in chapter 185, the maskless Quecchon gives Enigman (without his mask) a valentine chocolate.
