[Dark Abyss] Ghost

A mysterious Regular. No one knows who this Regular is. He only responds with beast-like grunts, and no one can understand anything he says. However, it is undeniable that he is a capable individual. He was one of the last three Regulars remaining on the Floor of Tests, and he was able to obtain the highest rank in the Spear Bearer Test. No one knows who he is to this day.
