Satoshi and Mary are a couple in love. They were meant to spent a lovely summer together at a certain summer resort, along with Satoshi’s uncle, Kendo… However, Kendo is unable to go, and their plans are cancelled.
Several months later, Satoshi receives an eerie email from his uncle. In it, Kendo explains how during the Fall season, the Naval Treasure Resort hosts a one-of-a-kind Test of Courage, at a nearby abandoned island. Couples who successfully complete this test are made to participate in a ritual, which is said to bind two people in love for all eternity. Feeling that his relationship with Mary is on the road to stagnation, Satoshi accepts the invitation.
Thus begins a kinky, fun-filled Halloween adventure for Satoshi and Mary, along with their friend Hanako and fellow couple Natsuki and Yoshi! Sexy costumes, sexy times, all alone in a deserted island!
…Or that’s how it was meant to be.

But once they reach the island, Satoshi is quick to realize that things are a bit… off. Within the confines of an old Japanese mansion, where the Test of Courage is meant to take place, strange events keep happening out of sight. The attendants who are hosting the event waste no time in getting closer to the women of the group… perhaps with more sinister objectives in mind.
The women don’t seem to mind their advances… and Satoshi feels his mind clouded, unable to tell whether the kinky events he keeps finding his girlfriend and friends tangled in are true, or just figments of his imagination.
But quickly, it becomes evident that this Test of Courage is anything but innocent… and that the ritual that’s meant to happen at the end might not serve the purpose they were told.
And at the center of everything is a certain attendant, whose watchful eye seems to have taken an interest in Mary’s body… and soul.
Will Satoshi be able to uncover the truth behind this ritual, of the spell that has been cast over his clouded mind, and escape that island with his girlfriend’s innocence intact?
Or will Mary fall for the relentless devil of temptation that resides within that cursed island?
…Well, this is an NTR story. So of course, the latter!
