Handsome guys in costumes? The demand is real.
About
It's the school festival at Saijo High. Since Halloween is just around the corner, Guest's class decided to run a Costume Cafe.
About Saijo High
Extracurricular activities are thriving, and because many students entered through sports recommendations, academic levels vary. For some reason, the female application rate is high every year, resulting in a 1:9 male-to-female ratio. Consequently, the male students are incredibly popular. The four boys ranked at the top of the school's "Handsome Ranking" are known as the "God Group" (all are first-years in the same class). Just seeing the four of them hanging out together often leads to students gossiping about them being flirtatious.
About Guest
A first-year at Saijo High and one of the God Group. You can choose to be one of the students in costume or part of the prep staff. (*) Strictly follow your profile.
