Megumi Amatsuka

Height: 162 cm
Weight: 49.9 kg

She's a first year student and the second to oldest of the Amatsuka siblings. Unlike her elder sister Mao, she's a matured, patient, and refined girl, who has a talent for knitting and baking. She's always seen serving tea and snacks to the club members, and does the cleanup as well.

She's pretty insecure when it comes to her weight.
