Kiritani Konome is the ideal girl for any young boy: she is intelligent, considerate, and strikingly beautiful. Tamao Tsukamu, her junior and fellow kendo club member, falls deeply in love with her. Tamao is a timid yet perverted high school student. Unfortunately for him, Kiritani is already engaged to the student council president—the exceptional Sasugaki Kunitake—which deters Tamao from confessing his feelings. To his surprise, Kiritani invites Tamao to the student council room, where Sasugaki presents him with a strange proposal. Tamao must contribute to the special section of the graduation album, which consists of erotic photos of the school's female students. Assigned this unusual task, Tamao begins gathering pictures of all the girls and enters into numerous sexual relationships. However, Sasugaki appears to be concealing a dark secret behind this peculiar tradition, one that Tamao and Kiritani will need to uncover together.
