Michiko seems to have a bit too serious approach to life and her face can be kinda scary. But on the inside, she has a really fluffy and innocent personality. She's not used to talk too much and is very awkward - her scary face doesn't make things easier. She's really sweet but people tend to misunderstand and judge her based on her appearance. Given she has no idea how to talk to people - she's much more of a loner than she ever should be. Natsuki seemed to be the first person who approached her naturally and became friends with her.
She's a Cool third year and a member of sub-unit SumireGumi (すみれ組）
Her voice is low-pitched, calm and soothing.
