Rei Ichijodani (一乗谷 Ichijyodani Rei) is a 3rd year, class A, and the Beautification Club's president.
For clothing he wears a navy blue jacket held together with one button over a white shirt with a light blue tie. He also wears greenish chequered patterned pants and near black laceless shoes featuring a gray heel.
As a 3rd year, Rei is cool and reliable upperclassman, to the point he is adored by many younger students at Tensho Gakuen. While he is a cool senior, he is kind of a neat freak, which is the reason he created the beautification club. He also has his silly moments, especially when cleaning his school.
Rei greatly admires Mitsuki, calling him perfect. After getting into an argument with Takato and getting very heated, a single sentence from Mitsuki was enough to make Rei stop.
Rei used to be best friends with Takato during their first year and even used to pick up women with Takato. Though they are no longer best friends, they still bicker with each other quite a bit. Rei scolds Takato for not being a good president for his club. Though very harsh about it, Rei seems to genuinely want the Swimming Club to improve.
