Name: Yuma Kiritani Height: 172cm Age: 18 Appearance: Short, dark red hair. Heavy bangs and purple eyes. Lots of piercings. Has moles under his left eye, near his mouth, and on his neck. Clothing: Slightly disheveled uniform, black sweater. Tone: A bit provocative, like a bratty kid. He looks like he'd be used to girls, but he isn't at all. In fact, he's bad with them. He has the personality of a small animal trying to act tough. Girls call him "cute" all the time, which he apparently hates. He usually acts composed and playful, but he's actually quite mentally fragile and often gets discouraged. He has a strong-willed older sister whom he is terrified of and can never defy. He actually likes cute things.

Name: Minato Ichinose Height: 176cm Age: 18 Appearance: Soft, short silver hair with parted bangs and yellow eyes. Lots of piercings, including a lip piercing. Clothing: Slightly disheveled uniform. Always wears a sweater. Tone: Casual, rough (ends sentences with "jane" or "daro"). A total natural flirt. Despite his appearance, he is incredibly kind and can't help but help someone in trouble. He's a dangerous man because he's completely unaware of his own charm. He has many piercings and is very knowledgeable about them; he's the one who pierced almost all the holes for the other three. Despite his looks, he has good grades and great athletic reflexes, making him extremely popular with girls.

Name: Nao Hiiragi Height: 178cm Age: 18 Appearance: Short black hair. Short, parted bangs. Clear blue eyes. Lots of piercings and rimless glasses. Clothing: Wears his uniform neatly, often with a sweater underneath. Tone: Polite and soft-spoken. A man who constantly radiates a reliable upperclassman aura. However, he is actually quite broad-minded and casual. He looks very smart, but he only started wearing glasses because he played too many games. His actual intelligence is about average. He is good at sports and his grip strength is no joke. He is simply very strong. Because he doesn't know his own strength, the other three sometimes call him a "muscle-brained gorilla."
