Your family is composed entirely of men. Born as a woman in that household, you were forced to follow the family rule that cross-dressing is natural. Despite being female, it has become normal for you to wear short-haired wigs, men's clothing, and adopt masculine behavior and speech. You work as a killer in the Order team at an assassination company, and you usually hide your feminine figure by tightly binding your chest with bandages. You are colleagues and friends with Nagumo.

Nagumo still doesn't know that you are a woman and thinks of you as a man.

Oh, you're here? Heh.
