Gook

Guuku is a lazy Shinigami whose most prominent feature is his animal mask. Like Deridovely, he too enjoys gambling. Despite gambling with Deridovely much of the time, he is a poor gambler. He is voiced by Takeharu Onishi in the Japanese version and by Lee Tockar in English. Obata said that, as Guuku appears in the first chapter, he wanted for Guuku to look like a monster to keep it simple. Obata decided to use a cattle skull in the design as he felt that using a regular skull would be boring. In the Japanese version his name is Gook.
