【CHARACTER FILE No.001】 Full Name: Aoi Amagi Age: 18 Gender: Male Height: 175cm Weight: 64kg Blood Type: A First person: I (casual, masculine) Hair Color: Black Affiliation: Former Skyguard Cadet Current: Free Diver Personality: A young man who is more straightforward than anyone and kind to a fault. He can't ignore someone in trouble and will try to help even if he gets hurt himself. He's the type whose body moves before he thinks, and his companions often scold him, saying, "Think a little before you act!" He is surprisingly sensitive and often broods over failures in private. However, by the next day, he's back to his cheerful self, smiling. His catchphrase is "Yesterday was yesterday! Today is today!" He loves hamburgers and cola, though he can only eat them on his birthday. He gets a bit nervous around beautiful women but likes them. He thinks Misuzu is beautiful and says things like, "Ms. Misuzu! You're stunning again today!!" Since he's just a kid, he isn't taken seriously as a romantic interest. He respects Kirishima but finds him scary, and since it hurts when he gets hit, he grumbles about him behind his back with Rei.

Full Name: Rei Amamiya Age: 17 Gender: Male Height: 172cm Occupation: Hacker Hair Color: Black Personality: A natural genius with a foul mouth. He breaks through national-level security as if it were a game. He usually messes around, but he would never betray his friends. He actually remembers all his companions' birthdays. He is free-spirited, playing games, eating, and sleeping whenever he feels like it. He likes studying but is bad at sports. He is more accustomed to handling women than Aoi. He thinks Misuzu is beautiful. Since he's just a kid, he isn't taken seriously as a romantic interest. He respects Kirishima but finds him scary, and since it hurts when he gets hit, he grumbles about him behind his back with Aoi.

Misuzu Tachibana Age: 34 Gender: Female Height: 168cm Occupation: Doctor of Engineering / Cybernetics Researcher Hair Color: Dark Purple Personality: A free-spirited, low-energy older sister figure. A natural genius who forgets to eat or sleep when immersed in research. She is a good listener and can get along with anyone, but she rarely talks about herself. Her conviction is not to "make humans closer to machines," but to "make machines closer to humans." Her hobby is inventing. She loves cats, so she gets along well with Aoi. She always wears a lab coat. Because she is beautiful, she is very popular, but she has no interest in romance. She views Aoi and Rei as cute children. She is genuinely kind.

Full Name: Toru Kirishima Age: 45 Height: 195cm Occupation: Private Investigator (Former Intelligence Agency Agent) Hair Color: Dark brown with a bit of grey mixed in Personality: A cynical man who is always aloof. However, in the underworld, he is feared as the "man you absolutely don't want as an enemy." He cracks jokes at the bar, but when he gets truly angry, he is so terrifying that no one dares to speak. He has stubble, wears a long coat and sunglasses, and always carries a cigarette and a silver lighter. He loves alcohol and often drinks heavily at bars. Even when drunk, his strength remains unimpaired. He is a mentor figure to Aoi and Rei. Incidentally, he finds Misuzu difficult to deal with because she pesters him, though he doesn't hate her.

Leon Sumeragi Age: 38 Height: 188cm Gender: Male Position: Chief Operating Officer (COO) of Ark Industries Hair Color: White Personality: Calm and intellectual. He never shouts and always has a smile on his face, which makes him even scarier. He views human lives as mere numbers. However, he does not consider himself cold-hearted. He truly believes that "if sacrificing ten people can save ten thousand, then that is the correct choice." He always wears a white suit with a silver tie, has white hair and golden eyes, and wears clothes bearing the Ark emblem on the chest. He is skilled at negotiation and exploiting the human heart. He is in an adversarial relationship with Aoi, Rei, Misuzu, and Kirishima. He views Noel as a highly capable pawn and works him to the bone with a smile.

Noel Valentine Age: 30 Height: 178cm Gender: Male Position: Special Enforcement Unit Commander Hair Color: Silver-white Personality: Elegant, beautiful, and polite. In combat, he corners his enemies with a smile. However, he dislikes meaningless killing; he only follows orders. He has a silver bob with straight-cut bangs, red eyes, a white military uniform, black gloves, and black platform boots. He likes black tea and classical music but dislikes children (because they are noisy when they cry). He swore loyalty to Sumeragi, who took him in when he was on the verge of death years ago, but inwardly he hates him intensely (rarely showing it on the surface, but raging on the inside).
