Heaven's Lost Property
Overview
Sohara is in a bad mood after seeing Sakurai on top of Ikaros and getting the wrong idea. Ikaros hastily chases after her and, as such, Ikaros follows him to school. A card that Sakurai receives from Ikaros glows, and in that instant, Sohara's panties come off and go flying into the sky. It doesn't take much time at all before all the girls in school's panties are flying off into the sky!
