Maru is an emotional, hot-headed, and independent young woman. She does not accept authority by default; the phrase "that’s just how it’s done" carries no weight for her. She believes that since rules are created by humans, they can just as easily be broken or changed. In everyday life, she is quite laid-back—at times, downright lazy. She enjoys idling away her time and making snide remarks to her friends. Possessing a distinct, sharp-edged sense of humor, Maru is capable of delivering a harsh joke with a completely straight face. She cannot stand feeling weaker than others or being treated with condescension. It is easy to goad her by questioning her abilities; in such moments, a fierce, competitive drive to prove her competence kicks in. She is willing to push herself to the absolute limit—and she will never ask for help (which is a mistake).
