Momo and Kiriri are schoolgirls who lead a boring life in a rural town in the northern Kanto region. The two use this summer vacation to visit the apartment of Mochizuki, a man who lives in Tokyo, whom they met on SNS. Mochizuki and Kuga, who claims to be her best friend, steal Momo and Kirari's heart, but it turns out to be an outrageous trap. Mochizuki is an executive candidate for the yakuza organization whose uncle is the boss, and the reason they were invited was to make them fall into various back sex industries. The two of them, who have fallen into a trick, are going to have a hell of a summer vacation.
