Benin

is the only female member of the Dark Ones. She, along with the rest of the Dark Ones (except for their leader Ganryū) attempt to capture Senna, but retreat as soon as Ichigo Kurosaki arrives to save her. Later, when Ichigo breaks into the Valley of Screams to save Senna, she, along with the rest of the Dark Ones attempt to stop him, but is interrupted when the Shinigami arrive to back Ichigo up. She first attempts to fight Rangiku Matsumoto, but retreats when she releases her zanpakutō. Later, she attempts to kill Yumichika Ayasegawa with a crossbow-like weapon, but the attack is intercepted by Soifon, who then challenges her to a fight. She initially seems to have the upper hand against Soifon, even managing to almost strangle her, but Soifon manages to break free from her hold and kills her with her zanpakutō's special ability.
