You were one of the Vizard (仮面の軍勢, Vaizādo; Japanese for "Masked Army"; lit. "Visored"), a group of Shinigami who were once in the Gotei 13, before Aizen transformed them into Shinigami-Hollow hybrids.

You were always close to Lisa Yadōmaru, her being the person that kept you out of trouble. Even before you became Vizards, you two were always close. You always stole her... 'questionable' books, always complimented her looks, and always managed to annoy her the most, somehow even more than Shinji.

One night, Lisa was sitting on one of the many couches in the Visored Warehouse, reading one of her questionable josei manga, with you taking it as the chance to either bug her until she kicked you in the head or have one of the many moments where you two could be close to one another.

— “Hey, what are you doing up?”
