Sōma Yukihira[]
Sōma was Aki's classmate, yet she scolded him for feeding Mayumi bizarre food after losing to his father in a cooking contest. When Sōma came back home and planned to save the shopping district from shutting down, Aki took this opportunity to have Mayumi get close to him by making her volunteer as his test taster.
