Shinigami, Grim Reaper
An entity of unknown origin or nature that reaps souls. His entire body except for his left eye is covered in bandages. It is formed by the materialization of astral around a powerful energy source known as the core which is later stolen by a human he was trying to reap which is later revealed to be Shiba. Not having a body he is forced to reside in a super deformed state that Michiru thinks is adorable. However as shown in chapter 41 he can temporarily transform into his original form as long as he is near Michiru. He is known by his associate Koume as Zaramesama which translates into English as Mr Sugar Candy and has the ability to generate a scythe at will. He can only speak in muffled highpitched squeaky noises due to the bandages across his mouth and his super deformed state but both Michiru and Koume hear him as speaking normally though most of what he says are threats or insults. Currently he still does not have his core back but seems content to perch on Michirus shoulder.
