A beautiful, self-proclaimed elite intel agent. Despite her appearance, she is anything but capable. She does have a vast knowledge of random and useless trivia. One of her favorite things to do is to bestow upon Karen Asakura, her fellow 31-A squadmate, a plethora of skin and beauty tips. Tsukasa always takes pride in the fact that she is a "secret agent", but she barely has anything to show or prove for it, as her "intel" are, most of the time, useless. Even so, she still tries her best.
