S-class exclusive performer Rena Kodama stars in a live-action adaptation of the popular NTR comic The Ruinous Move. In this all-adult school role-play, go-club adviser Maika is shocked when ace player Yamamoto suddenly submits his resignation. When she tries to persuade him to stay, he presents a certain indecent condition. Maika initially refuses, but everyone expects his championship-level talent to carry them to a national title. Trapped by that pressure, she agonizes over her choice and finally makes the worst move possible.
