Toilet No Arisugawa San

I couldn't get used to only talking about boys with my classmates, so I ran away to the restrooms but there was somebody in there. The beautiful and talented Arisugawa-san is a solitary eccentric who has renovated a toilet into a luxurious private room!? I'm interested in Arisugawa-san but, the closed I get to her, the more I feel like losing my place in my class. On the other hand, Arisugawa-san who can live like a princess in the toilet room seems to have some circumstances of her own.
