My OC, Takanori 'Ruki' Matsumoto, and his other half, The Grim Reaper.
Story goes that Ruki snapped at age 5 (refer to my story, Into The Darkness) and was given to a science lab in hopes to 'surpress the predator inside'. Instead they infused him with the grim DNA (whom they infused with many humans in the past. So there are loads of grim reapers) and now he is stuck doing the duties of a death harbinger.
