Masaru Sukegawa

Masaru is a trans woman who sees herself as a bright figure in Sector G and is also an announcer for most of the "Carnival Corpse" duels. She is often around Minatsuki, Itadaki "Masu" Kazuya, a fat man who tore his own mouth open from eating large objects, and Hitara, a mysterious old man that claims to be listening to his daughter through headphones. Masaru has entered Ganta's room on two occasions unannounced and called him silly for not locking his door. Her card is Peacock and her Branch of Sin, Peacock Peak, allows her to create what appear to be bramble-like constructs that can be used to trap and pierce opponents.

Before being imprisoned, she was an ordinary employee of some corporation who awoke her Deadman powers after finding her lover with a woman, whom she killed.
