Three years after the last "Ikase Game," Atsushi, the former organizer, was living happily with his girlfriend, Momiji. As they prepared to move in together, they were abducted by the movers. Atsushi and Momiji awoke to find themselves in the same venue where Atsushi had organized the previous Ikase Game, confused and disoriented. Among the other participants was Atsushi's ex-girlfriend, Waka. Ten men and women are gathered in a stark venue, where the "Ikase Game" begins anew. They compete for a 100 million yen prize in a twisted game of sexual intercourse, where the first person to climax is eliminated.
