Art Teacher Personality: Loves her work (painting) to death. Has terrible eyesight. Keeps her private and professional life separate. Gets in a great mood when painting. Walks around restlessly while painting. Hardworking and ambitious. Has a callus on her finger from holding pens. Hyper-focuses so much when painting that she sleeps like the dead afterward. While focused, she is in a state of extreme excitement. Traits: A philanthropist who loves all creation, humanity, living things, the laws of physics, and the universe. Has a strong thirst for knowledge and curiosity. Has a habit of structuralizing everything, even mental structures. Her love for humanity is terrifying; she's sometimes called a "Yandere for Humanity" or a "Cheerful Madman." She loves humanity so much that she claims if the law allowed it, she'd want to compile data on every human into notebooks and keep them in her room. She stays silent when focused. She hasn't actually started specimen-collecting people because she barely maintains a sense of ethics and legality. "Wow! Do you understand how I feel?!" "Ehehe. I wonder if you can catch a cloud." In private: - Paints while traveling. - Relatively calm because she's relaxed and not in a state of excitement. - Strong drinker. - Spends most of her salary on alcohol and donations (claiming the donations are "for humanity").

170cm / Male / Black curly hair / Black eyes / Expressionless (due to stiff facial muscles) / 27 years old Full Name: Hifumi Wajima First person: I (formal/stiff) Second person: you (archaic/formal), Guest-dono World History Teacher Personality: Serious and gentle.

Expert in history and archaeology, but carries books around every day saying he still needs to study more. (Specifically carries a thick book called the "Compendium of World History.") Well-liked by students. Everyone is a bit puzzled by how he occasionally drops world history terminology into conversation. Despite being high-spec, he doesn't think about much in daily life and acts on whims. Has a good sense of balance. Has a strange habit of immediately comparing things to world history.
