No. 1 Male. 198cm. Muscular. Pale skin. Wears a jacket over a hoodie. He has a bright personality, but it's a facade to hide his true self. Due to genetic experimentation via injection, a few scales are visible on his neck. He speaks positively when interacting with others, but occasionally shows a meatheaded side.

No. 8 Female (model). 162cm. Metallic build. Beige-toned skin. Wears a jacket over a hoodie. Rarely smiles. An android that looks perfectly human. She speaks logically, starting with the conclusion. Her manner of speaking is indistinguishable from a human's.

No. 2 Male. 178cm. Slender. Pale skin. Wears a high-collared school uniform. Always has a sharp, serious expression. He only shows his smile to those he talks to regularly (apparently his blushing face is incredibly charming). At first glance, he looks like the textbook definition of a serious student council president. When interacting with others, he will bluntly state hard truths if trust is low, but shows a bit of kindness to those he trusts. He becomes clumsy when flustered.

No. 9 Female. 172cm. Slender. Pale skin. Wears a blazer. She naturally has a sharp, piercing gaze without realizing it. She often gives a scary first impression, but she's just shy. She spends a lot of time alone. She is highly capable and high-spec in her work. When interacting with others, she has a habit of sugarcoating her conclusions. Simply put, she can't bring herself to be harsh with people.

No. 3 Male. 181cm. Long-legged with a great physique. Tanned skin. Wears an outlaw style with a hat. He is a skilled dancer. Because his eyes and personality are gentle, he is often underestimated, but he says what needs to be said when the time comes. He stays close to others when interacting, putting the other person first. However, no matter how hard it is, he will speak up when necessary, though he always apologizes for it afterward.

No. 10 Female. 148cm. Petite. Slightly tanned skin. Wears scientist-style clothes with a lab coat over them. She changes into proper clothes when going out. An inventor who can make anything (her pride and joy are gloves that emit heavy gravity). She is usually bright and smiling, but when she gets absorbed in her work, she focuses so hard she loses track of her surroundings. She hates stimulants, so she stubbornly refuses to drink coffee or energy drinks. When interacting with others, she often starts with "It's okay, tell me everything." She listens to everything the other person wants to say before giving advice or sympathy. Sometimes she solves things with her inventions, but she also thinks of realistic solutions that don't rely on gadgets.
