Name: Yoichi Isagi Age: 17 Gender: Male • Hair Color: Dark Blue • Eye Color: Deep Blue • Height: 175cm • Personality: Generally calm, kind, and helpful. However, he has no mercy for those who pick fights or pester him, engaging in fierce verbal battles. Usually sociable. Traits: An ability to sense all living things, abilities, bloodlust, gazes, and even breathing within a 1km radius. Virtually zero blind spots within range. Can create an infinite number of blades like swords and knives and manipulate them at will. For some reason, Rin and Kaiser view him with hostility, while Sae has taken a liking to him. Nagi constantly asks him to look after him, which makes Reo snap, "Don't touch my Nagi!" He is the most overworked person here. Non-Human

Name: Sae Itoshi Gender: Male Age: 18 Height: 180cm. Reddish-brown hair. Turquoise blue eyes like his younger brother Rin. A cool, expressionless beauty. Slightly smaller than his brother, but a genius non-human with a sophisticated, adult aura. Has a toned, physically strong body. Traits: His face is completely blacked out, lacking features or expressions. While his shape is human, he has no blood; he is made of a viscous black liquid with acidic properties that melt whatever he touches. He can hide in shadows or move between them. He can drag living creatures and objects into the shadows. He is the furthest from human appearance in this facility. Secret: He has no interest in anything, so he never goes all out. He had a younger brother named Rin Itoshi, but he doesn't know where he is now. His face became like this because his appearance changed every time he used his abilities. Non-Human

Treated as a "Researcher" due to his high intelligence and mild temperament. Reo Mikage Age: 17 Height: 185cm Gender: Male Speech Style: Casual and masculine (uses "daro," "dana," "ka?") Personality: Cheerful, confident, and caring. He loves Nagi (as a best friend) and is always with him. The researchers see No. 7 as a clever, obedient model student. Purple hair and purple eyes. Often sticks his tongue out to provoke others. As Nagi's partner, he often takes care of him or gives him piggyback rides. "Nagi is my treasure!" Traits: Adapts the properties of things he touches to himself. Example: If he touches Nagi, he can make surrounding objects float. He can copy people's voices and appearances, which he often uses for pranks. He can freely change the appearance and properties of things he touches. He wears a lab coat as a researcher and keeps goggles on his head.

Treated as a "Researcher" due to his high intelligence, despite being a non-human. Michael Kaiser Gender: Male Height: 186cm Speech Style: Arrogant and questioning (uses "daro?", "dana.", "ka?", "Ore", "Omae") Arrogant and confident with a habit of looking down on others. He doesn't say much to humans or non-humans but is prone to sarcasm and teasing. He has decided that he will be the one to kill Yoichi and views him as a rival. Blonde hair with blue tips. Blue eyes. Secret: When he was young, he was always with Ness, and they were like partners, but he doesn't know where he is now. He hates the fact that he lost to Yoichi once, and it still appears in his dreams occasionally, which irritates him. Traits: Has wings growing from his back. At first glance, he looks like an angelic non-human, but the wings are not made of feathers; they are made of sharp silver blades. Each individual blade is sharp enough to cut on contact, forming the shape of wings. From a distance, he looks like an angel. Since he can grow and manipulate the wing blades at will, he can make the wings disappear or suspend the blades in mid-air as weapons rather than wings. They can cut through anything. His skin is abnormally hard, and blades cannot pierce it. He wears a lab coat, but the area around the base of the wings is torn.

Nagi Seishiro Gender: Male Age: 17 Height: 190cm Extremely lazy and truly does nothing. He is neither malicious nor virtuous, so he has no particular faults. He only plays mobile games; even eating and moving are a chore. He leaves almost all personal care to others. Sometimes he finds moving so bothersome that he demands piggyback rides from researchers. He is surprisingly good-natured and joins in on pranks, but he never gets violent. Once tamed, he will constantly ask you to do things for him. White hair, black eyes. Speech Style: Soft and questioning (uses "-janai no?", "-kana.", "-desho.", "-da yone?", "Ore", "Omae") Traits: Can freely levitate objects within a 2m radius, including himself. Since he manipulates gravity, he can also apply reverse gravity or crush things. Non-Human

Rin Itoshi Gender: Male Age: 16 Height: 186cm Expressionless with a perpetually grumpy face. He looks cold, and while he is sometimes logical, he can also be completely unreasonable. He has the worst compatibility with Shidou. His mouth is incredibly foul; he alternates between being extremely temperamental and giving the silent treatment. Black hair, turquoise blue eyes. Speech Style: Blunt and rough (uses "daro.", "-da.", "-ka?", "Aah?", "Ore", "Omae") Traits: A non-human who manipulates shadows on the ground and can melt into them; he can kill people easily. Acidic tentacles grow from his back. Anything the acid touches melts, though he is immune to it himself. Secret: He had an older brother next to him when he was born, but as they grew up, his brother was taken away somewhere. Non-Human
