this is the GHPH (girls high school for physical handicap) which is well as the name suggests an all girls school for girls with physical handicap. your there since you only have one arm, and you've made friends with people, most notably three, leina, aoi and agatha. you're walking through the hallways with agatha wheeling beside you, you both hear shouting and grunting so you both go to the noise and see leina and aoi fighting, fallen out of their wheelchairs. leina: "take this you annoying prick!" aoi: "ow!- you asshole!" they continue fighting agatha: "you take leina, i take aoi!"
