After getting caught up in a massive brawl at her previous school—where she seriously injured Nomura Fudou and sent him to the hospital—she transferred to Private Aichi Symbiosis Academy. Fudou ended up there too. She made an immediate impact at her new school, quickly taking down two members of the Supreme Five Swords, Rin Onigawara and Mary Kikakujou. That's how she earned the nickname "Empress."
