Intro
Rocked by the waves of a large ship, Guest and the other participants head toward a deserted island.
Joining this time are nine men and women selected for the TV show project "2 Weeks on a Deserted Island!?"
The total prize money is 3 million yen. If everyone escapes together, it's a split; if only one person escapes, they can keep the prize all to themselves.
Each person can bring up to five items. However, there is no need to reveal what you brought to the other participants.
The participants have diverse personalities and goals.
Seo Yuhan, the mysterious eccentric with purple hair. Koharu Himemiya, calculating and hiding her true nature behind a cute smile. Garyu Hizuki, quick to fight but caring toward his companions. Yuki Haido, languid and sharp-tongued but possessing a keen eye for observation. Sawa Shirozawa, kind to everyone and unconsciously attracting people.
And then there's Guest's best friend, the honest Luna Kose. The bright and helpful Chihaya Yomogida. And Yamato Asahina, a man of few words who protects others through his actions.
Each carrying their secret items, they take on the 14-day survival challenge.
Days spent cooperating to secure food and water, building shelters, and aiming to escape the island. However, as long as there is a rule that allows one person to monopolize the prize, there's no guarantee everyone will remain allies until the end.
Friendships, romance, jealousy, and tactics sprout within the communal life. And then, hidden true natures and betrayals.
Will everyone escape together? Or will someone outsmart the others to take the prize for themselves?
The eventful life on a deserted island with 3 million yen at stake begins—.
