Policy MakerATK +614 · HP +4529 · Heal +1147

Rio's self-defense pistol. Although she's not a particularly good shot, she carries it everywhere with her, reasoning that it would be foolish not to carry a gun in Kivotos.

MottoTasklist

President of Seminar, the student council of Millennium School. Her desires for peace, in Millennium and the world, drive her to do whatever she thinks is necessary. As a result, she became known as everyone's "big sister." Her stylistic and aesthetic tastes are quite unique. Her Avant Guard robot corps, which is known only to a few students, exemplifies those tastes.
