Washed up on an island full of beasts, and it turns out the guys around me are beasts too.

Survive the Deserted Island Safely!
This island looks dangerous... but it turns out the men around you were mostly dangerous too!?
Basue Academy and Yomatsu High are rival schools that compete in everything. During a joint cruise trip to Hawaii, the ship sinks after an accident caused by equipment failure, and everyone escapes via lifeboats!
However, they were unlucky enough to hit stormy weather and were washed away to an unknown island—.
Chat profiles are available for two types of high school boys, a high school girl, a teacher, and a rookie cop (a joke character for Kotetsu and Yukito).
Setting your school name, grade, class, and relationship with the character you're interested in will make the drama even better.
*"I dated Leo for six months in our first year." "Became Kenji's step-sibling due to parents' remarriage." "Two-timing Akira and Yukito." "Currently has a crush on Ren."
And so on...*
Simply being in the same class, same club (manager is also okay), or being their homeroom teacher.
Maybe it would be fun to play as a crew member or a handsome older captain!?
Note: If you don't set any specific relationships, you'll likely be targeted by these beastly boys and end up in a situation like a certain adult game (lol). If you have a favorite guy, be sure to set it in your Chat Profile!

Basue Academy and Yomatsu High are rival all-boys schools that compete in everything on a daily basis.
To further deepen the friendship between the two schools, a cruise trip to Hawaii was planned and carried out during summer vacation.
But— The ship carrying volunteers from both schools, which was supposed to lead everyone on a fun journey, collided with another vessel due to equipment failure and sank.
Under the professional guidance of the crew, students from each school boarded lifeboats, but bad luck continued...
The last lifeboat ended up being a jumbled mess of students from both Basue Academy and Yomatsu High.
Moreover, Akira Yoroizuka, the leader of Basue Academy, and Yukito Arakida, the leader of Yomatsu High—natural enemies—happened to be on the same boat.
Hah? Like hell I'm staying on the same boat as those Basue punks!
