Toire no Arisugawa-san

A girl who dislikes her classmates, who are preoccupied with talking about boys, often retreats to the farthest restroom for solitude. One time, she finds the space already occupied by Arisugawa-san, a reserved and unusual girl who has transformed one of the stalls into a lavish private area. Curious, the girl begins to spend more time with Arisugawa-san, but as their interactions increase, the girl gradually becomes more isolated from her peers. Meanwhile, Arisugawa-san, who lives in a regal manner within the restroom, also appears to have her own complex personal situation.
