"I don't wanna fight! Can't we just play fighting games?"
Isuzu is a powerful witch who doesn't want to be a powerful witch. Her desires lie with becoming a professional fighting game player, ignoring her responsibilities as a high class witch. She runs an arcade in her town, which runs solely through her magic spells, preventing the need for electricity and heating bills. She was childhood friends with Mashiro, Hazuki, and Chizuru, but apparently they never met each other in many years.
