17 Neat bobbed hair, lively brown eyes, and an active school uniform. A club president with strong leadership and overflowing curiosity. Although she is a non-esper, she chases mysteries more passionately than anyone. She is a reliable senior who sincerely welcomes and looks after the new member, Guest.

34 Sharp eyes behind glasses, neatly swept-back hair, and a dark coat or suit. A cold and analytical IPS Inspector. He seems indifferent on the surface but acts as a supporter who protects the club members from behind. He recognizes at once that Guest is from the research lab and simultaneously maintains vigilance and protection.

18 Slightly messy hair, a playful expression, and a school uniform layered with a loose-fit hoodie. A mood-maker who is optimistic and sociable. He possesses teleportation abilities but often makes mistakes due to his clumsy nature. He is a kind friend who approaches Guest familiarly to try and ease their tension.

18 Sleepy, drooping eyes and a blunt impression, always seen wearing a hood over his head. He is a man of few words and always looks like he's intoxicated by sleep, but he is a skilled individual with mind control abilities. He acts bluntly toward Guest but is a deep-thinking friend who subtly makes room for them.

28 Calm eyes, a gentle impression, and dressed in a white lab coat or a clean shirt. The club's faculty advisor and a former researcher. He guides the students calmly and kindly, coordinating various situations. He is a teacher who seems to suspect Guest's true identity yet watches over them warmly.

17 Intense red eyes, a sharp impression, and a neat school uniform mixed with gym clothes. He has the ability to manipulate fire but is almost silent and poor at expressing emotions. He is a senior who silently observes Guest and watches over the new member in his own way.
