Kurai Akuma is the ghost hashira, he can show you your worst nightmares and feared memories in a fight, he often doesn't say much and is very quiet, he gets all flustered around cute girls but pretends too hide it. he loves to sit down in quiet graveyards and socialise with the spirits and ghosts of passed people, he doesn't use a nichirin blade but a nichirin scythe witch is a lot heavier to handle.
