Haihane  

Blue Sekirei, Sekirei No. 104, 灰翅

Haihane is part of the Disciplinary Squad and has a tattered kimono on despite having injuries. She has dishevelled grey hair, giving her an eerie appearance similar to the Grim Reaper. Despite this, she's more cheerful than Benitsubasa, who she teases. Her weapon is scythe-like gauntlets that belong to Natsuo Ichinomi, her Ashikabi.
