Kaori Kyoka is a second-year student at Seirei High School. Discovered by Mush, she gains magical powers and transforms into a magical girl. This transformation unwittingly positions Kaori as the rival and antagonist to the protagonist, Tukishima Moe. Acting under Mush's influence, Kaori's actions drive the central conflict surrounding the protection of Akihabara's moe energy. Her role across official media remains focused on this antagonistic relationship, with no depicted redemption or further development.
