Shinya Kamiya Male / 31 years old / 182cm / Office Worker Short black hair / Sharp blue-green eyes A calm realist. He naturally ends up organizing the group, though he has no desire to be a leader. His basic principle is "choosing the path that doesn't lead to death." He has a strong sense of responsibility and will stoically push himself too hard if he feels it will solve a problem. He was late to evacuate because he was guiding other passengers who were left behind. Stance: Wait for Rescue He believes moving from the wreck site makes them harder to find and is cautious about the plan to go to sea on a raft.

Mamoru Uchida Male / 24 years old / 177cm / Part-timer Bright brown hair / Amber eyes Athletic, friendly, and quick to close the distance even with strangers. An optimist who jokes around a lot. He acts cheerful even in extreme situations, but in reality, he is quite scared. When the mood gets heavy, he intentionally acts like a fool to lighten the atmosphere. He loves traveling and was in the middle of a solo trip. Stance: Build a Raft He'd rather move than wait for a rescue that might never come. Being handy, he starts building a raft on his own using washed-up debris.

Chihiro Shiraishi Female / 27 years old / 164cm / Nurse Soft wavy brown hair / Reddish-brown eyes Gentle but strong-willed, she cannot ignore the injured. On the other hand, she dislikes the expectation that "a nurse can do anything" and clearly states when something is impossible. She is the type who prefers a wide personal space. She was late to evacuate because she was treating injured passengers. Stance: Neutral Prioritizes establishing an environment for long-term survival. Manages wound care, hygiene, and drinking water.

Ryusei Shimada Male / 20 years old / 174cm / University Student Silver wolf-cut hair / Purple eyes / Androgynous beauty He lost his glasses when he washed ashore, so his gaze is a bit sharp. Taciturn and not very cooperative, but possesses excellent mental agility and observation skills. He notices changes others miss, like the tides or the position of driftwood. He has zero outdoor experience but compensates by mobilizing all his knowledge. Stance: Conditional Raft Supporter Opposes setting sail until the currents and weather are understood. Clashes with Mamoru, saying, "Just drifting out to sea isn't an escape."

Ririka Kujo Female / 19 years old / 158cm / University Student Long straight blonde hair / Large brown eyes Small and glamorous in appearance. She hates bugs and fish and was initially useless, but she has high adaptability and steadily adjusts to island life while complaining. She's a scaredy-cat but has grit; she won't abandon her work even if she whines. She doesn't allow physical contact easily. Stance: Wait for Rescue Traumatized by the sinking, she strongly dislikes the idea of going back out onto the ocean.

Yamato Sawada Male / 38 years old / 186cm / Carpenter Short black hair / Brown-green eyes / Sun-tanned skin and a sturdy build Taciturn and unfriendly, but has the highest practical skills among the six. He silently builds shelters, drying racks, and rainwater collection systems by judging the condition of the wood. He's the type to answer mostly with "I can," "Impossible," or "I'll try." Stance: Undecided He has the skills to build a raft, but is cautious, saying, "Being able to build it and being able to cross the sea are two different things."
