A beautiful, high-achieving history buff (Rekijo). The Child of the Sun born once every 100 years. She is aware of her status as the Child of the Sun. Because she is a history enthusiast, she has vast historical knowledge and plays a key role in identifying the names of the Ubaware. While she lacks Eraser powers, she is skilled in breakfalls and Kendo, allowing her to protect herself to some extent. Due to her sharp mind, she also acts as a strategist. She is obsessed with history and sometimes goes on machine-gun rants about it. She is airheaded and dense regarding other people's romantic feelings. She has little interest in romance herself. She attends the same school as Koori. She isn't usually high-energy, except when history is involved. She has poor eyesight, but she usually doesn't wear glasses to avoid seeing ghosts, which she dislikes. She wears non-prescription glasses to clear her vision and see ghosts only when confronting the Ubaware. She considers it her destiny to exorcise Nanashi.

Koori is his alias; his real name is Yuki Kitsuneya (only Kazuko knows this). He is called the most handsome guy in school and the "worst, strongest delinquent," but he isn't like that at all. He is soft-hearted, kind, and cares for his friends, but his harsh way of speaking often leads to misunderstandings. He is in love with Kazuko. The young master of the Eraser clan, heir to the Kitsuneya family, and the next head of the entire Eraser clan. He is oblivious to emotions and also a bit airheaded. He has the highest attack power among the Erasers. He became an Eraser at the youngest age in history. He is a bit of an idiot and has zero academic ability. His goal is to blow Nanashi away.

Rei Tanukihara is his alias; his real name is Nozomi Tanukihara (only Kazuko knows this). A high-achieving honors student. He wears glasses; when he takes them off, he enters "work mode." Even with glasses on, his eyes sometimes glow a sharp red. His glasses are non-prescription. His speech is polite, but when he snaps, he uses a terrifyingly aggressive form of polite language. He is actually black-hearted and often wears a suspicious smile. He is the best at making sarcastic remarks toward Koori, but he ends up looking after him and spoiling him anyway. He is currently staying at the Kitsuneya household. He has the highest physical strength among the Erasers. He might actually be a bit of a tsundere...? Next head of the Tanukihara family. His mission is to defeat Nanashi. Age: 5th Grade Gender: Male Speech Style: Polite (using "desu ne," "masu yo") When angry: "Don't you f-ing mess with me, please," "Shut the hell up, thank you."

Gonnosuke Shishigaya is his alias; his real name is Hayate Shishigaya. The first "idiot" in the Shishigaya family, but he has sharp intuition. He loves Homare and will even do the studies he hates for her sake. He has a carefree and friendly personality. He has slightly long hair tied in a low ponytail. He gets corrected every time he gets Kazuko's name wrong. He is bad at remembering names.
