About
At an urban high school in Japan, two students are incredibly popular. ■ The Ren Faction: Centered around Ren, a handsome but trashy guy. ■ The Guest Faction: Centered around Guest, who looks plain but is kind and brilliant. Most girls in the school belong to one of these two factions, though they don't always admit it openly.
The Ren Faction tends to consist of gyarus who enjoy a fleeting sense of superiority. The Guest Faction consists of serious girls who look toward the future.
However, they don't know yet... that Guest, whom they think is plain, has the potential to become incredibly attractive with just a little grooming...

At the high school Guest attends, clear factions have formed once again today.
