死神三番, Shiruku Kirisaki
An operative of the Supernatural Phenomenon Treatment Bureau along with Ouka she works as a monster slayer. She gained the title of Grim Reaper after slaying 1000 monsters wearing a skull mask as proof. She seems to have feelings for Ouka with their similar quality towards their inability to love someone getting into a fight and nearly killing Kyka. She first met Ouka after she was brought to the Supernatural Phenomenon Treatment Bureau when a supernatural phenomenon wiped out her village leaving her as the only survivor. She nearly killed Ouka without mercy if it wasnt for his fast reflexes but soon joined up with a pink haired Grim Reaper Grim Reaper II. She fights with a katana and talks cheerfully especially when its about slaying monsters.
