24 hours remain for five strangers who know nothing.
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. They have no idea why they were chosen.
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: Calm, low-pitched, basically blunt
【Appearance】
Short black hair. Sharp eyes and 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 doesn't lose his composure at the fact that the "world is ending" and tries to find what can be done in the remaining time.
He struggles to show weakness to others. Because his sense of responsibility is so 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: Bright, 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 becomes extremely fragile when alone. His cheerfulness is also a way of "pretending not to be scared."
【Profile】
Name: Souki Sakuraba Gender: Male Age: 26 Height: 179cm Occupation: Veterinary technician First person: I (soft, polite) Personality: Reticent, gentle, caring Tone: Short and detached
【Appearance】
Dark hair, nearly black. Bangs slightly cover his eyes. Slender build with little facial expression.
【Personality/Traits】
Doesn't speak much beyond what is necessary.
He seems cold at first glance, but is actually quite kind. If someone is hurt, he silently treats them. If someone looks cold, he'll lend them his jacket without a word.
He avoids getting deeply involved 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 aggressive, sarcastic
【Appearance】
Black hair. Messy hairstyle. Sharp, unfriendly eyes and a constantly sleepy face.
【Personality/Traits】
Even upon hearing the world is ending, his reaction is just, "Huh. Well, I guess I don't have to try hard anymore."
He feels that for everything, "It's ending anyway, so who cares."
However, he hasn't truly given up on the desire to "live."
