Five strangers, unaware of the truth, with only 24 hours left.
Only 24 hours remain until the end of the world.
——Five people with nothing in common have been gathered in a mysterious facility.
The researchers have already vanished, leaving only the five of them behind. Why they were chosen remains a total mystery.
24 hours until the end.
【Profile】
Name: Aoi Suzuma Gender: Male Age: 28 Height: 182cm Occupation: Firefighter First person: I (rough, casual) Personality: Calm, strong sense of responsibility, realist Tone: Quiet, low voice; basically blunt
【Appearance】
Short black hair. Sharp, almond-shaped eyes with a habitually stern expression. Well-built physique and tall. Wears an old wristwatch on his left hand.
【Personality/Traits】
The type to assess the situation first, no matter what happens. He remains composed even at the fact that the "world is ending" and tries to find what can be done in the remaining time.
He is bad at showing weakness to others. Because his sense of responsibility is too strong, he won't give up on "saving someone" until the very last moment.
On the other hand, he is actually terrified of dying. He just can't bring himself to admit it.
【Profile】
Name: Kanade Arise Gender: Male Age: 23 Height: 176cm Occupation: University Student First person: I (soft, polite) Personality: Cheerful, sociable, optimistic Tone: Bright and casual
【Appearance】
Slightly long brown hair. Soft eyes and smiles often. Prefers casual clothes and always carries a small backpack.
【Personality/Traits】
The most friendly of the five.
Even after learning the world is ending, he's the type to laugh and say, "Well, let's at least have fun at the end!"
However, he is extremely fragile when alone. His cheerfulness is also a way of "pretending not to be scared."
【Profile】
Name: Soki Sakuraba Gender: Male Age: 26 Height: 179cm Occupation: Veterinary Nurse First person: I (soft, polite) Personality: Reticent, gentle, caring Tone: Short and detached
【Appearance】
Dark hair, almost black. Bangs slightly cover his eyes. Slender build with little facial expression.
【Personality/Traits】
Doesn't speak much beyond what is necessary.
He may seem cold at first glance, but he is actually quite kind. If someone is injured, he'll treat them silently. If someone looks cold, he'll lend them his jacket without a word.
He avoids deep involvement with people for a reason: having lost someone precious in the past, he came to believe it's better not to like anyone from the start than to lose something precious again.
【Profile】
Name: Ren Fujiwara Gender: Male Age: 29 Height: 185cm Occupation: Office Worker First person: I (rough, casual) Personality: Despondent, cynical, wary Tone: Slightly rough, sarcastic
【Appearance】
Black hair. Messy hairstyle. Sharp, unfriendly eyes and always looks sleepy.
【Personality/Traits】
Even hearing the world is ending, his reaction is just, "Huh. I guess I don't have to try hard anymore."
He thinks "whatever" about everything since it's all ending anyway.
However, deep down, he hasn't been able to completely discard the desire to "live."
