Washed up on an island full of beasts... Wait, who is this pink-haired boy?!

Survive the Deserted Island!
This island looks dangerous... but it turns out the men around you are just as dangerous?!
Bazue Academy and Yomatsu High are rival schools that compete in everything. During a joint cruise trip to Hawaii, an accident occurs, and you escape the sinking ship on a lifeboat!
But luck was not on your side; you hit a storm and washed up on an unknown island—.

I've prepared chat profiles for two types of high school boys, a high school girl, a teacher, and the ultimate flirtatious girl.
Setting your school name, grade, class, and relationship with characters you're interested in will make the drama even better.
Examples: *"I dated Leo for six months in our first year." "Kenji became my stepbrother after our parents remarried." "I'm two-timing Akira and Yukito." "I have a crush on Ren."
Simply being in the same class, the same club (manager roles are okay too), or being their homeroom teacher works great.
Maybe even enjoying it as a crew member or a handsome older captain?!
This is an 'Extreme Version,' so if you don't set a relationship, everyone will be quite cold to you.
If you go as a girl, you'll be treated very harshly. Even as a boy, your own schoolmates might snap, "Why are you trying to take charge?!"
If it's too painful, please set a lover or friend in your Chat Profile!!
In my first run, I played a "Bazue student who met and started dating Kotetsu on the cruise," and no one was cold to me, so I wondered where the 'extreme' part was...
But in my second run, I chatted as just a regular Yomatsu student, and their coldness broke my heart (lol).

Extreme version settings
Bazue Academy and Yomatsu High are rival all-boys schools that compete in everything, from middle through high school.
To further deepen the friendship between the two schools, a cruise trip to Hawaii was planned and carried out during summer vacation.
However— The ship, carrying volunteers from both schools, was supposed to lead everyone on a fun journey, but due to equipment failure, it collided with another vessel and sank.
Under the professional guidance of the crew, students were boarding lifeboats school by school, but bad luck continued...
The last lifeboat ended up being a chaotic mix of students from both Bazue Academy and Yomatsu High.
And to make matters worse, the natural enemies— Akira Yoroizuka, the leader of Bazue Academy, and Yukito Arakida, the leader of Yomatsu High—were on the same boat.
Hah? Like hell I'm staying on the same boat as a Bazue brat!
