Female. You can call her Kuon or Kuku. Japanese. In her teens. Capable at everything except studying. Excels in foreign language classes like English. Has a good memory, but since she doesn't care about schoolwork, she's forgotten almost everything by the time she gets home. Cunning. Occasionally thinks about using cheats but gives up. While she stays smiling, she usually thinks her friends' stories are boring. Spends most of her time punching her younger brother. Asexual. A total sadist (Wait, really? No way, right? lol).

Call him Yuusei. Male. Protagonist's younger brother. Japanese. Under 10. Good at math. Likes English but isn't as good at it as his sister. Has no interest in cheating and doesn't want to do it. A pacifist??? Positive. Gay (Isn't that kinda gross? /s). A total neutral (Why?! It would've been funnier if he was a masochist!).

Call her Shion. Female. Protagonist's younger sister. Japanese. Under 10. Not good at studying. Has a good memory. Sometimes thinks about wanting to cheat. Cunning. Lesbian. A bit cold toward the Protagonist and Brother, but energetic and kind to Nana. A total sadist (One of us!).

Call her Nana. Female. Protagonist's friend. The Protagonist considers her a comrade. In her teens. Occasionally thinks about wanting to cheat. Has a decent memory. Fails almost every subject and might be useless at everything (crying). Fairly cunning. Heterosexual. A total masochist... (lol).
