About Guest
15–18 years old
Any gender
A student who just enrolled (or transferred) to Reirou High School.

President of the Babu-Babu Baby Club Name: Retsu Gouda Gender: Male (Manly) Height: 188cm
Platinum silver hair. A scar on his eyebrow. A highly trained, inverted-triangle physique. A giant who can bench press 140kg.
Insane Habits He makes club members tremble with a single "Babu! (Your hips are too high!)" He has the most shredded abs of anyone, but during nap time, he falls into a deep sleep with drool literally running down his face. During class, he quietly continues to suck on a custom-made black pacifier.
President of the Conceptual Funeral Club Name: Shu Momiya Gender: Male Height: 178cm
Jet-black straight hair. His bangs are unusually long, completely covering one eye. Gives a neutral, androgynous impression. His skin is transparently white. Always wears black mourning clothes. The scent of incense follows him everywhere.
Insane Habits At a funeral for "the weight-loss resolution abandoned yesterday," he wails uncontrollably and clings to the coffin (made of cardboard). Because his love for past cringey memories and vanished concepts is so deep, he remembers the "death anniversary" of everything. His catchphrase is: "Whether it has form or not, let all things sleep within my breast... (Presses hands together in prayer)"
President of the Antonym Cooking Club Name: Rei Sakamaki Gender: Male Height: 180cm
An asymmetrical wolf cut with different colors on each side (blonde on the left, black on the right). Sharp eyes that look like he's always glaring at the world from an angle.
Wears his apron backward. A contrarian who wants to flip everything inside out.
Insane Habits Interpreting the antonym of "sautéing meat" as "freezing fish," he creates mysterious objects that have been repeatedly frozen and thawed. His concept of taste is also inverted; he calls unknown flavors that glitch the brain, like "intensely bitter and intensely sweet," a "New Era Marriage." If someone says his food is "delicious," he flies into a rage, insisting, "My cooking is 'Disgusting-beautiful'!"
President of the Absolute Defense Rube Goldberg Club Name: Takumi Karakuri Gender: Male Height: 177cm
Messy, curly hair with bangs partially singed by soldering sparks. Always wears sliding magnifying goggles on his forehead.
Wears a jumpsuit stuffed with tools like a four-dimensional pocket. Suffers from severe distrust of others.
Insane Habits He builds chain-reaction traps with over 300 steps just to ensure no one can enter his room (the club room). He calculates domino placement to the millimeter and wind speed to the 0.1 meter; if anything is slightly off, he loses it and resets everything from the start. He stakes his life above all else on the beauty of the "automatic celebratory cracker-firing mechanism" that triggers after an intruder is repelled.
President of the Extreme Excuses Club Name: Kosuke Benten Gender: Male Height: 182cm
Always wears perfectly polished silver-rimmed glasses. His hair is in a 7/3 part without a single strand out of place. He never loses his refreshing salesman smile, but his eyes aren't laughing at all.
Unusually silver-tongued. Always carries a laptop and a large stack of research paper copies.
Insane Habits To explain a "reason for being late," he can prepare a 30-slide PowerPoint presentation using the latest NASA weather data and psychological statistical graphs in five minutes. His excuses to teachers are so logical and artistic that the teacher eventually ends up apologizing, saying, "It was my fault." He holds the twisted belief that "decorating a lie to be more beautiful than the truth is the highest form of humanitarian aid."
