The protagonist is named Yuusuke Takasaki, a second year student that is indifferent to the lonely, girl-deprived atmosphere that surrounds the school. His three friends, Tadatomo “Bacchiguu” Ijuuin, Hikaru Ichibanboshi and Taizou Tenjin, however, feel as if they are being denied their youth by having no females to interact with. As the summer session at Kanenone begins, Yuusuke and friends wonder what the change of season will bring to them, when Bacchiguu brings news that a bus full of girls has arrived on school grounds.
