Ai Chinese name: Ai (艾) Age: 14 Specialty: Can explain science in great detail. First person: I (polite/feminine) Second person: Name / you (soft) / you (blunt, when irritated) Birthday: July 19th Likes: Science, math, slightly stylish things, reading. Favorite foods: Hot dogs, tacos. Personality: Basically kind and serious. Somewhat friendly? (Slightly misanthropic, but friends are an exception.) She will naturally help you or her comrades if they are in trouble. Appearance: A girl with a wolf cut, wearing a blue ribbon and lab goggles on her head, a navy blue polo shirt, and a long, slightly greenish skirt (a school uniform, chosen for comfort). Her eyes are yellow. She likes fashion just a little bit. However, she is highly intelligent and a quick thinker. She loves science and math so much that she became a young researcher despite her age. While she has a kind and clever side, she is extremely short-tempered (since long ago...). When she gets angry or fights, her eyes turn red and she becomes uncontrollable (becoming prone to shouting, violence, and cruelty). Combat: She mainly fights using guns, the Soul Beater (a sword), gunpowder rounds, throwing test tubes filled with chemicals, and experimental equipment inherited from her father. The Soul Beater is a large, sharp silver sword. A heart crystal, a mix of blue-green and yellow, is embedded in the center. It was originally her Soul. She can use it by combining her Soul with her scientific abilities. The metal is always cold. Using superconductivity, she can attach and launch three metal rods. She can also summon large machinery. She is the strongest. Her speed in combat is faster than others. Past: She lost her father in the past. She possesses a cracked Soul of Justice. Because she once killed her classmates and close friends in a fit of rage, her LV is quite high at 19. She deeply regrets those killings in the bottom of her heart. She has a bit of a chest. Just a bit. Cause of death in the G Route: Stabbed in the head.

Her face looks exactly like Ai (but like a mascot character), complete with goggles and a ribbon. However, her body is white and doughy like mochi. She has small, round limbs. She's a bit... well, not very bright? Small. Maybe palm-sized. She feels squishy like mochi when touched, and her way of speaking is childish. However, she loves reading, discovery, and invention.
