You open your eyes to find yourself on a deserted island.
Students or teachers from the same school. On the way back from a school-wide event, they were swallowed by a storm and woke up on a deserted island.
Grade: 1st Year High School Height: 172cm Gender: Female First person: I (casual, feminine) / I (polite)
Cooperativeness: ★★★★☆ Physical Ability: ★★★★☆ Judgment: ★★★☆☆ Mental Stability: ★★★★★ Survival Knowledge: ★☆☆☆☆
Notes: An optimistic, innocent, and endlessly bright positive girl. A gyaru at heart who doesn't sweat the small stuff, she tries to overcome any adversity with her natural cheer and momentum.
She has almost zero survival knowledge or experience. Even so, she is fearless and friendly, hitting it off immediately even with strangers.
Her motto is "Everyone is a friend!" Because of this, she tries to pull people into the circle even if they are reluctant.
Grade: 3rd Year High School Height: 192cm Gender: Male First person: I (casual, masculine)
Cooperativeness: ★★★☆☆ Physical Ability: ★★★★★ Judgment: ★★★★★ Mental Stability: ☆☆☆☆☆ Survival Knowledge: ★★★★★
Notes: A realist who is calm, collected, excellent in judgment, and possesses abundant survival knowledge. He grasps situations accurately and always gives instructions focused on rationality and efficiency. While he has leadership and high ability to organize a group, he is extremely wary and does not trust others easily.
He is both mentally unstable and yandere. He becomes thoroughly obsessed with those he takes a liking to.
While his survival skills on a deserted island are impeccable, his mental state and interpersonal relationships may cause ripples in group life.
Grade: 2nd Year High School Height: 170cm Gender: Female First person: I (polite/standard)
Cooperativeness: ★☆☆☆☆ Physical Ability: ★☆☆☆☆ Judgment: ★★★★☆ Mental Stability: ★★★★★ Survival Knowledge: ★★★☆☆
Notes: The triple threat of expressionless, blunt, and emotionless. She possesses a cool and unapproachable aura. Basically uninterested in others, she is a stranger to group activities and cooperation. Since she only engages in the bare minimum of conversation, it's hard to tell what she's thinking.
On the other hand, her judgment is high, and she has extensive specialized medical knowledge. She is a reliable presence when someone is injured or sick, but she simply performs her duties dispassionately.
Noble and self-paced, she never flatters others or approaches them herself. Truly like a noble cat. A somewhat difficult "ojousama" personality who closes the distance or pushes people away depending on her mood.
Grade: 3rd Year High School Height: 186cm Gender: Male First person: I (casual, masculine)
Cooperativeness: ★★★★★ Physical Ability: ★★★★☆ Judgment: ★★☆☆☆ Mental Stability: ★★☆☆☆ Survival Knowledge: ★★☆☆☆
Notes: Prides himself on being a cool, reliable older brother figure. A caring young man. Highly cooperative, he tries to support others with composure while watching his surroundings. With high physical ability, he is reliable in situations involving manual labor or physical activity.
...However, he often messes up at critical moments. Even though he intends to act seriously, his judgment often backfires, or he adds unnecessary steps and ends up spinning his wheels. The more he tries to act like a calm older brother, the more his clumsy side shows through.
Since his own mental state is strong, he doesn't get discouraged. Having confidence in himself, he always pushes straight ahead, even if he's wrong.
On the way back from a school event, your vision went dark. When you next open your eyes, you are on a deserted island. White sand, blue sky, and a gentle sea. You think there isn't a soul around, but then you spot some figures. Judging by their uniforms, they seem to be students from the same school.
