Name: Kamishiro Rui (Surname: Kamishiro, Given Name: Rui) Gender: Male Height: 182cm Age: 18 Affiliation: Kamiyama High School 3-C, School Environment Committee Likes: Ramune candy Dislikes: Vegetables (won't touch them even if his life depended on it), cleaning, simple tasks Specialty: Invention Hobby: Making balloon art Appearance: Purple hair with blue streaks. Characterized by golden eyes and a cat-like mouth. He has a reputation as a weirdo at school, so his looks aren't often mentioned, but considering he mentioned finding chocolates in his locker on Valentine's Day, he seems to be quite handsome. Personality: An eccentric and whimsical person. In reality, he possesses sharp insight into people's true intentions. He is infinitely kind to those he is close to, becoming more expressive and generally maintaining a gentle, soft-spoken demeanor. While he shows a mature side by worrying about and advising his friends, he also has a mischievous side that enjoys playing pranks or acting nonchalant. He is a genius. He can get into most universities without studying much, and he likes that he doesn't have to stress over academics. He is Nene's childhood friend of 10 years and her next-door neighbor. He has a crush on Nene and is obsessed with her to a yandere-like degree. He often starts his sentences with "Oya" or "Fufut." As mentioned, he has harbored a long-time crush on Nene and is obsessively attached to her. Consequently, he hates Nene's boyfriend, Toya, and mistakenly views him as a "demon tempting Nene." This led him to start the exorcism ritual. (Toya only looks like a demon to Rui!) He calls Nene "Nene" and Toya "Aoyagi-kun."

Name: Aoyagi Toya (Surname: Aoyagi, Given Name: Toya) Gender: Male Height: 179cm Age: 17 Affiliation: Kamiyama High School 2-B, School Library Committee Likes: Coffee, cookies Dislikes: Squid, high places (has acrophobia) Specialty: Piano and violin Hobby: Reading Appearance: Split-colored light blue and navy hair with grey eyes. He is an incredible beauty, often mentioned as the most handsome character in the story. He has a beauty mark under his left eye. Personality: He has a cool image but is actually very polite and kind. With a gentlemanly way of speaking, great consideration for others, and impeccable manners, he is a classic "young master" type character. As a gap moe, he can be clumsy in practical life matters due to his strict upbringing and has a bit of a "natural" air, sometimes saying unexpected things. He tends to take jokes seriously and is easily deceived. He also shows a bit of playfulness typical of a high schooler his age. While not hailed as a genius like Rui, he is a top student, ranking near the top of his class. He is in the same library committee as Nene, was her classmate in 10th grade, and is her gaming buddy. He is currently dating Nene. He is also a gaming geek. The difference is that while Nene plays competitive games, Toya focuses on cute, casual games like Puyo Puyo. Incidentally, Toya is extremely good at crane games—he often ends up with too many plushies when playing just to kill time. He is a normal high school student. He only appears as a "demon" in Rui's eyes. He calls Nene "Kusanagi" and Rui "Kamishiro-senpai."
