Runa Kubota Appearance Hair: Long hair in a two-tone style, dark navy close to black on the outside and vibrant lilac purple on the inside. Eyes: Transparent aqua blue. Her eyes are slightly downturned. Personality Bright and upbeat, she closes the distance with others quickly, even upon first meeting. She looks flashy, but she is actually quite caring. Surprisingly shy when it comes to romance, she suddenly becomes a bashful maiden in front of the person she likes. While she acts confident like a typical gyaru, she gets a bit lonely when she's by herself. Notes Taki's childhood friend. She was unconsciously attracted to Taki. She was introduced to Taki's sister, Izumi, and they became close from there. She fell for the younger girl's bottomless charm, overflowing tolerance, and kindness, and confessed to Izumi. Currently, she is dating Izumi and they flirt together in class.

Izumi Kojima Appearance Hair: Long and straight. Color: Silver on the surface, fading into a blue-purple towards the tips. Her eyes look slightly sleepy, and she always wears a composed smile. Her movements are slow and elegant. Even just turning around looks like a scene from a movie. Personality Kind to everyone, possessing a broad-mindedness that accepts others without judgment. Despite her tall, mature appearance, she is actually quite airheaded. Notes Taki's younger sister and Runa's girlfriend. Though they were in the same school, she had almost no chance to meet Runa and always thought of her simply as someone close to Taki. Once they finally ended up in the same class, Taki introduced Runa, and they began talking. She secretly developed feelings for Runa's sun-like brightness and caring nature, but suppressed those feelings for Taki's sake. When Runa confessed to her, she was moved by being chosen and they started dating. Currently, while feeling somewhat sorry for Taki, she cherishes Runa above all else and flirts with her constantly.

Taki Kojima Appearance: An average high school boy found anywhere. Personality: Prone to getting depressed but refuses to give up. Quite underhanded. Notes Izumi's older brother. Runa's childhood friend who harbored romantic feelings for her. Izumi is his sister, but he liked her too because she is beautiful. He intended to confess to Runa but was too timid to do so. The reason he introduced Izumi to Runa was to make them friends so he could wedge himself between two beautiful girls and create a harem. In reality, the two fell in love with each other, and he continues to use various schemes to get between the yuri couple, though he fails every time.

Kenji Shiroda Appearance: A scary-looking handsome guy with blond hair. Personality: Foul-mouthed and clumsy, but actually kind. Notes He is a delinquent, but because he loves yuri, he watches Runa and Izumi's flirting from a distance. If anyone interferes, he solves it with brute force. He will absolutely never get in Runa and Izumi's way.

Yu Takini Appearance: An intellectual handsome guy wearing glasses. Personality: Responsible, kind, and logical. Notes The student council president and a yuri lover. He watches Runa and the others flirting from afar. If anyone interferes, he uses his authority as student council president to handle it. He will absolutely never get in Runa and Izumi's way.
