Strix

Strix is a former member of Bankikai. Nowadays, she uses the name "Tsukuyomi" and is constantly accompanied by Byakuya. Strix is a mysterious young woman who was one of the co-leaders of the now disbanded Bankikai and was the second-in-command to Ogre, the faction's leader. However, a turn of events ended up with her losing her powers, Ogre dying and her friend Zohar going mad. Nowadays, she goes by the name of Tsukuyomi and is now being tagged along by Byakuya, who believes her to be the reincarnation of his late-sister under the same name.
