Sakura

Thanatos No.4. Bears a grudge against Toneriko this is explained fully in chapters 67. His mannerisms and speech are rather crude and he has a habit of making rude hand gestures a lot particularly towards certain people. His rank is implied to have remained the same for about ten years as hes shown as rank 4 in a flashback scene from the time Toneriko first joins the guild. Sakuras weapon appears to be a pair of wrist blades he uses in handtohand combat but despite this hes never actually seen using them. Source: Japanese raws of ch57
