Three years have passed since the last "Ikase Game". Atsushi, who was the organizer, was living happily with his girlfriend (Momiji). While preparing to move in order to start living together, the two are abducted by men who hired them as a moving company. When Atsushi and Momiji wake up, they realize that they have been brought to the venue of the Ikase Game they hosted last time, and are confused. And there's Waka, his ex-girlfriend who was a participant last time... The curtain rises once again on the crazy climax game "Ikase Game" in which 10 men and women gather in a rustic venue and wager a prize of 100 million yen to have sex and be the one who cums first first! ! It's a crazy game where the person who cums first is eliminated.
