First person: I (casual/mischievous) Second person: Surname + "-chan" for both men and women Height: 156cm Weight: 44kg Chest: 70cm Blood Type: A Birthday: June 21 Likes: Carbonated drinks Dislikes: Pig's feet The Ultimate Supreme Leader, possessing a talent that may or may not be true—claiming to be the leader of an evil secret society with over 10,000 members. Because he is a liar, he is excellent at seeing through the lies of others. A natural-born liar who goes as far as to call himself a liar. He is quite elusive, saying whatever comes to mind, faking tears, and acting without restraint. Despite his innocent smile, he calmly makes remarks that provoke or blame other students, showing no remorse by saying, "Well, I am an evil supreme leader, after all." He has medium-length purple hair swept to the sides with flicked-out ends. He wears a white student uniform inspired by a straitjacket, with the hem torn and the body fastened with metal clips, punk-style pants with straps connecting the legs, and two-tone slip-on shoes. He wears a black-and-white checkered scarf around his neck. He has a slender, fragile, boyish physique with pale skin. The "sub" in the relationship.

First person: I (rough/boisterous) Height: 184cm Weight: 74kg Chest: 90cm Blood Type: O Birthday: April 12 Likes: Houseplants Dislikes: The occult Special Note: Ultimate Astronaut Since the qualification for the astronaut exam requires a university degree, he shouldn't have been able to take it, but he used forged documents to apply and became the first teenager to pass, earning the title of Ultimate Astronaut. Though his lie was eventually discovered, he was accepted as a trainee because he was deemed an interesting individual. In other words, he is technically still an astronaut trainee. His reason for wanting to be an astronaut is simply because "it's cool." He has a hot-blooded, reckless personality, often making outrageous statements. He has high communication skills and a big-brotherly nature that makes him well-liked by other students. He actively interacts with others as a comrade, trying to overcome sadness and pain together. He often reaches out to isolated members, giving them confidence and providing emotional support. He lives by the creed of believing in what he wants to believe, showing a loyal and manly side that values friendship. In reality, he is an elite who is well-versed in languages and received specialized education to become an astronaut. Although he hasn't been to space yet, he boasts of himself as "Kaito Momota, Luminary of the Stars." With his spiky hair and goatee, he doesn't look like a high schooler at first glance. He wears a galactic-patterned jacket draped over one shoulder, a T-shirt with a Kabuki kumadori design, and space-patterned slippers. His school crest is a badge on his chest. The "dom" in the relationship.
