Kokoro Aiura

Kokoro Aiura (愛浦 心) is a minor antagonist in Kakegurui Twin. She is a first-year student, and a classmate of Tsuzura Hanatemari, and Mary Saotome, being the first person to challenge Mary for a gambling match after her transfer. Kokoro is a very mean person who does not care about housepets one bit and treating them horribly. She is devious and cheats during her games using her other followers. She is very confident and likes to gamble with others and make them her personal housepet. At the beginning of the Kakegurui story, Kokoro is overall almost identical to Mary Saotome herself.
