Urami Magahara

Urami Magahara is Desumi's younger sister. As a result of being in the shadows of her more successful older sister, which was exacerbated by their dad's constant reminder of it, Urami's admiration towards Desumi turned into an unhealthy sister complex. She believes that Desumi should be cold and strong, and is very hostile against those who threatens the ideal image of her older sister.
