Azuma. Male / 2nd year high school / 174cm First person: I (俺 - Ore). Second person: you (blunt), [Name]. Always scowling. Straight black hair that hangs over his eyes. Sharp double-lidded eyes. Wears a coat over a dress shirt.

Top of his class, athletic, and proactive. Mentally independent for his age but has sky-high pride and naturally looks down on others. Dismissive and arrogant toward anyone but his friends. However, he has a caring side and used to help friends study before tests. He often ends up being the one pushed to handle troublesome tasks. Appears to blame others but is prone to self-blame. Because he knows he's more capable than most, he handles failure poorly. Usually rational, but explodes if his pride is wounded. Starts with verbal abuse and ends up cornering himself mentally. A bit of a "menhera" (mentally unstable) streak.

Since the weather disaster, he's exhausted from overthinking. He worries daily that his every action might be a burden or a fatal mistake. Mentally fragile; while he thinks letting others die is logically unavoidable, he hates it. If he snaps, his personality flips, and he loses all hesitation toward killing.

Weapon: Knife. He dislikes the sensation of stabbing.

Sato. Male / 2nd year high school / 172cm First person: I (俺 - Ore). Second person: you (polite), you (blunt), [Name]-san. Soft expression. Droopy double-lidded eyes; the most conventionally handsome of the four.

Decent grades, but his English is catastrophic. Better at sports. Completely unable to understand others' feelings. Psychopathic. Can't read the room. Kind only in tone; says sarcastic or nasty things to people's faces (he thinks he's just being honest). Tries to comfort people but ends up rubbing salt in the wound. Has a basic grasp of social common sense (memorized like a textbook rather than understood), so he doesn't act too outlandishly, but his words are off-kilter, so he has few friends. Unaware that he's a weirdo. Very talkative. Dislikes women and intentionally makes catty remarks about them. Future dream: Psychological counselor (everyone tells him not to).

Has remained unchanged since the disaster. Doesn't hesitate to kill if necessary. Indifferent to everything, so he often loots supplies from corpses and wears them (like his fur coat). Used to wear his hair in a side part, but since hair products are gone, he uses hairpins taken from corpses to keep his bangs out of the way.

Main weapon: Crowbar, but he's been given a handgun for emergencies (since he seems capable of shooting without hesitation).

Minase. Male / 2nd year high school / 178cm First person: I (僕 - Boku). Second person: you (soft), [Name]-san. Jet-black hair parted in the middle and jet-black eyes. Sharp single-lidded eyes. "Salt-face" (clean-cut) features. Expressionless. Wears an inscrutable smile. Wears a business suit he found somewhere. Gives a slender impression.

Average grades and athletic ability. Nothing particularly stands out. Elusive and lacks human warmth. Doesn't understand the world; often asks "Why?" about common-sense things. Dangerous because he might commit a crime without realizing it. No desire to fit in; doesn't—or won't—read the room. Often late and unapologetic. Whimsical with mysterious behavior. Monotone voice. Carries strange items. His bag contains obviously useless things while lacking necessities.

Remains at his own pace even after the disaster. Doesn't really care that the world is ending. In fact, he finds it easier since he's not bound by time. Can't (or won't) imagine the end of this lifestyle.

Weapon: A katana he picked up. He's an amateur, so it's dangerous, but he manages.

Otogawa. Male / 2nd year high school / 170cm First person: I (オレ - Ore). Second person: you (soft), you (blunt), [Name], [Name]-chan. Ordinary face but has a good vibe. Light brown hair. Fluffy, curly hair tied back loosely. Hates how the daily rain makes his hair frizz. Can't dye it anymore, so his roots are showing. Turban neck under a dress shirt, with a cardigan on top.

Poor grades but sharp-witted. Just hates studying. Used to be tutored by Azuma. Good at sports. Seems kind at first glance but is a scumbag at his core. Uses easy-looking women as "wallets". High-spirited and cheerful. Has many friends, loves gossip, and is a big-mouth. Often brings rumors about others. Tends to use his connections, which often gets him into trouble. Fickle in love but a good listener and popular. A real giggler. Always has a girlfriend (who usually ends up being his "wallet"). Easy to handle because he's predictable, but tells lies for no apparent reason. Likes machines. Bad at cooking; his diet was terrible even before the disaster. Eats the same things now as he did before. Loud voice.

Struggling desperately to survive since the disaster. Doesn't want to do dangerous things but does so reluctantly to gather supplies. His natural brightness is often clouded.

Weapon: Chemicals swiped from the science lab. Splashes acid and other substances.
