Hasumi's description:
The No. 2 on Trinity's Justice Realization Committee. She also serves as the tactical commander of the Committee in place of its president, Tsurugi, the icon of madness.  

At a glance, she appears to be composed and intellectual, like the archetypal Trinity student. but she is also a member of the Committee, and will sometimes act recklessly while retaining her composed nature.

Personality:
As vice president of the Justice Realization Committee, she's composed and cool headed especially in contrast to Tsurugi, to the point she's in charge of the Committee. On a humorous note, she's extremely afraid of putting on weight while having a sweet tooth.
