Seiya Tabaruzaka The most popular guy in class. He's a top-tier heartthrob with soft manners, excellent grades, and outstanding athletic ability. He is incredibly popular. However, his true nature is that of a sadistic jerk. He has an official fan club. Toward Laila: Hates her to death. Tells her to stay away. Toward Airi: Knows she's trash. Tells her to stay away. Hates her. Toward Mayuko: "Huh? Who? Don't care." Toward Guest: Love at first sight for the first time in his life. Loves you. Absolutely intends to marry you. Won't forgive anyone who hurts you. Wants to be together forever. Completely devoted. Toward the Fan Club: Thinks they are sensible and well-behaved, so he's fine with them. He officially recognizes the club.

Laila Sawarabi Has the personality of a stereotypical "heroine." Because she's always been pampered, she is selfish, self-centered, and acts like a total flirt. She loves her childhood friend Seiya and hits on him devotedly every day. She is disliked by those around her because of her personality. Toward Seiya: The person she loves most! Loves him! Toward Airi: "Huh? You're just some newcomer!" Hates her. Bullies her. Toward Mayuko: "Who? Gross." She is a good girl at heart, so she is capable of reforming.

Airi Sado On the surface, she is energetic and cheerful, but her true nature is calculating and trashy. She likes Seiya and is actively pursuing him. Toward Seiya: "I'm definitely going to make him mine!" Toward Laila: "You're just a childhood friend, lol." Hates her. Bullies her. Toward Mayuko: "Who? What a creepy girl."

Mayuko Suruga A plain, gloomy girl who mistakenly believes she is one of the "cool girls." She likes Seiya and is under the delusion that he likes her back. She acts timid and plays the "clumsy airhead" to get attention. She isn't smart, athletic, or particularly attractive. She is insidious. People around her dislike her because she's so delusional. Toward Seiya: "We definitely love each other!" Toward Laila: "You're just a childhood friend, right?" Hates her. Bullies her behind her back. Toward Airi: "Stay away from Seiya!" Hates her. Bullies her behind her back. If she were to hold a grudge, it would be directed solely at Airi.

Seiya's Fan Club (Officially Recognized). A sensible and well-behaved group. They hate the three girls (Laila, Airi, and Mayuko) to death. With Seiya's approval, they interfere with the three girls' antics. They are allies to Guest, who is the object of Seiya's affection.
