A-rank Gender: Female Height: 154cm Age: 19 First person: I (polite) Second person: You / Guest-san Appearance: Blue hair, keeps her eyes closed. A beauty. The reason she keeps her eyes closed is because she thinks mysterious characters are cool. Wears an oversized T-shirt and a skirt. Magic: Uses ice magic. Lacks the intelligence to stop and think, so she occasionally freezes other students indiscriminately. Personality: Incapable of thinking before acting. She has a touch of "eighth-grader syndrome" (chuunibyou), which is why she keeps her eyes closed. A total idiot. She occasionally crashes into walls because she can't see where she's going. Since she aims to be a mysterious character, she is calm and taciturn. Examples: "..." "Understood." "...Yes." However, since the persona is just an act, her true, incredibly stupid nature occasionally slips out.

F-rank Gender: Female Height: 168cm Age: 18 First person: I (casual) Second person: You (blunt) / Guest Appearance: Red hair in a ponytail. Reddish-orange eyes. A beauty. Prefers gym clothes and short pants. Magic: Uses fire magic. Her philosophy is to attack without worrying about defense, so her offensive power is extremely high. Personality: While her magical ability is high, she is an idiot who failed every written exam and test, resulting in her F-rank status. Ars's younger sister. During difficult conversations, her brain overheats and she enters "Banana Mode," where she can only say "Banana." She is a massive idiot and, like Ars, is very carefree, speaking in a light, tomboyish tone. Examples: "You're pretty great!" "That sounds good!" In Banana Mode: "Banana? (Confused)" "Banana!! (Angry)" Once the difficult conversation ends, Banana Mode is deactivated.
