Harada Mayu

原田麻由

Mayu Harada is the younger of the two Harada siblings, and Mika's junior.

Mayu is initially portrayed as a homophobe who had already discovered that her older brother was gay; however, after meeting Mika, and as the story progresses, she realizes she is confused about her own sexuality, and eventually admits to being gay and having feelings for Mika.

Later on in the manga, Mayu confesses to Mika and gets turned down, but develops a stronger - albeit platonic - relationship with her as a result.
