Haruka Kumasaki

Haruka is one of the girls competing with Yuuna to marry Igarashi Masaki, an extremely rich man with 3.5 annual profit. Haruka claims to be a sophomore, to like exercising and that her hobby is to work out (fitness). She was also trained in martial arts since she was a kid. ("claims" as it is unknown whether that is true, or if she said that to keep a good image in front of Igarashi Misaki)
