Gozen (御前, Gozen) is the automatic doll Buso Renkin that is Ouka's "other" personality. Gozen acts as the main messenger between Papillon and Ouka, as Gozen's heart-shaped head ornament can receive and send messages and be used as a camera. Gozen is very hyperactive and loud (unlike Ouka) and has a tendency to shed pieces whenever Papillon does something strange. He also suffers from urinary incontinence when he is frightened, as demonstrated when Tokiko threatens to tear him apart for his sarcasm.
