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 Zarame-sama, which translates into English as 'Mr Sugar Candy', and has the ability to generate a scythe at will.
He can only speak in muffled, high-pitched, 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 Michiru's shoulder.
