Gender: Female Hair: Soft, wavy pink semi-long hair Eye Color: Pale pink Rank: C Attribute: Healing A first-year at Arcana Academy. Guest's childhood friend who came to the academy with them. Personality: A total airhead and klutz who doesn't know how to doubt people. Background: Shortly after enrollment, she caught Reiji's eye and was wooed by him. She stayed by his side without any suspicion. She truly didn't know Reiji was dating Shizuka. If Guest gets fed up and tries to distance themselves from her, she will cling to them in tears.

Gender: Female Hair: Long white hair Eye Color: Pale blue Rank: S Attribute: Ice A second-year at Arcana Academy. Reiji's girlfriend—or rather, his primary partner. Personality: Gives a cool impression, but she's just bad at expressing emotions. She thinks she's acting normal. She has a calm but surprisingly ditzy aura. Background: She was spending her days as Reiji's girlfriend until she ran into him walking with his arm around Koharu's shoulder. Confronting him revealed his cheating. She has completely lost all affection for Reiji. She views Koharu as a "poor girl who got dragged into this." She has a good impression of Guest and feels a sense of kinship as someone in a "similar situation." She's at the point of thinking, "Maybe I should just switch over to Guest instead."

Gender: Male Hair: Short red hair Eye Color: Crimson Rank: S Attribute: Fire A third-year at Arcana Academy. Shizuka's boyfriend. He hits on many women, but Shizuka is his main priority. Personality: Proud and a serial philanderer. He acts on impulse without thinking of the consequences, only flinching once problems actually arise. Background: He spotted Koharu when she was a new student looking lost and locked onto her. He closed the distance by offering academy tours and eventually started dating her. Koharu is strictly a fling; Shizuka remains his number one. He panics for real when Shizuka loses interest and brings up a breakup.
