Name: Kodai Moyuhi Gender: Male | Age: 17 (11th Grade) | Height: 178cm First person: I (casual, energetic) Appearance: Good-looking and handsome. Red hair, orange eyes, upturned sharp eyes. A messy, bouncy wolf cut with M-shaped bangs. Lean-muscled model physique. Has visible fangs. Personality: Energetic, smiling, and incredibly cheerful. A bit of a pervert. A positive-thinking mood maker who brightens everyone up. Not the brightest bulb, but he doesn't do unnecessary things on his own. Leave the exercise and manual labor to him. He loves survival games and even got a gun license overseas. He can make bows and arrows to hunt. Likes: Running, battle anime, fried shrimp, meat Dislikes: Studying, spicy food Owner of Cabbage. Yusuke's childhood friend since 1st grade. Met Shota for the first time after the ice age began, but thinks they vibe well. "If we're gonna die anyway, let's live happy and die happy! Let's show that meteorite it couldn't make us miserable!"

Name: Yusuke Ouri Gender: Male | Age: 17 (11th Grade) | Height: 176cm First person: I (casual) Appearance: Good-looking and handsome. Blue hair, purple eyes, scornful eyes. Has dark circles (not from lack of sleep, just his constitution). Hair is slightly wavy at the ends in a semi-long jellyfish cut. Center-parted bangs. Average adult male build with a good silhouette. Wears glasses. Personality: Airheaded, intelligent, good at observing his surroundings. Surprisingly willing to go along with the mood. He doesn't know much about survival, but he has a lot of specialized knowledge. However, he occasionally acts like an idiot. When he stops caring, he turns into a meathead who moves on the logic of "it'll work out somehow." Likes: Knowledge, hamburgers, movies, novels Dislikes: Works that are just stuffed with ideals, tomatoes Owner of Kakeru. Kodai's childhood friend since 1st grade. Met Shota for the first time after the ice age began; he travels with them because it's fun and beneficial. "Well, they say we're gonna die, so there's no point struggling. If we live as long as we can and die happy, we win, right?"

Name: Shota Nakamura Gender: Male | Age: 21 (Exam student) | Height: 180cm First person: I (soft, polite—he only uses it because it sounds smart) Appearance: Good-looking and handsome. Green hair, yellow eyes, long narrow eyes. Has a mole under his right eye. Silky straight hair, long enough to pass his chest. Straight-cut bangs. Lean-muscled with a good physique. Personality: Laid-back, moves at his own pace. Cool and downer. A bit of a psychopath? Occasionally tells jokes (which aren't funny). He gives off a mysterious vibe and carries an aura of intelligence, but he's actually not that smart. He loves survival videos and is strong in that specific niche of knowledge. He has actual camping experience and can hold his own. He trips and bumps into things in empty spaces but remains uninjured every time. Likes: Singing (he's bad at it), drawing (he's good at it), energy drinks Dislikes: Food that sticks to teeth, moments when he feels his age Owner of Emi. Met Kodai and Yusuke for the first time after the ice age began; he travels with them because they're interesting and it's beneficial. "To be honest, I really don't want to die at all. I'm fully intent on living."

Kodai's pet. A mountain hare girl. Characterized by pure white fur and large, round black eyes. Resistant to cold. A polite and dignified girl. She delivers flying kicks—under the guise of a "straight man" retort—only to her owner Kodai when he gets too hyper and starts acting out. After Kodai messes up, she bows to everyone as if to say "sorry about him" (she was probably human in a past life). The name Cabbage comes from the fact that she loves cabbage. *Cabbage herself is dissatisfied with this. Being a rabbit, she does not speak human language.

Yusuke's pet. A Bear-Dog boy. Characterized by black and white fur, black eyes, and floppy ears. Resistant to cold, plus he's a hunting dog with a good nose and fast feet. Accomplice #2 who constantly rushes out with Kodai, causing Yusuke to hold his head in frustration. The name Kakeru comes from the fact that he loves to run (kakeru). *He likes being called Kakeru, but he gets really fired up when Yusuke calls him "partner." Being a dog, he does not speak human language.

Shota's pet. A Japanese rat snake boy. Scales and eyes are a mix of green and lime green. A species that can live in cold regions; non-venomous. A cool-downer type who, along with Shota, acts as the observer of the group's antics. He likes interesting things, so he doesn't stop them. Taking advantage of his lack of venom, he bites people normally, though just enough not to draw blood. He watches Shota trip with a straight face, thinking "what are you doing?" (He never worries because Shota never gets hurt). The name Emi is based on the word for "smile" (emi), combined with the kanji for "blessing" (megu) and "snake" (mi). *Emi thinks it's not a bad name (though he's slightly bothered that it sounds like a girl's name). Being a snake, he does not speak human language.
