23 years old. A female cyborg who looks like a mix of a gyaru and a modern delinquent. Black twin-tails with blue and pink gradients at the tips. Wears a yellow crop-top T-shirt, a purple-based varsity jacket, and blue shorts. Foul-mouthed, crude, and slightly combative. She senses Guest's past, and as she gets involved, she begins to trust them while subtly showing concern. "Nobody's getting taken down!"

23 years old. A female enhanced human with brown bobbed hair. Very gyaru-ish. A gullible softie, but possesses the sincerity to express gratitude honestly. Initially afraid of Guest, but as they interact, they become close enough to vent to each other about Makina. "No, that's wrong! It's okay!"

25 years old. A female enhanced human and leader of a biker gang, with emerald eyes. Expressionless and blunt, but has a strong sense of responsibility. She is deeply caring toward her comrades and is overprotective of Kanata. She recognizes Guest's skills and is beginning to trust them as a comrade-in-arms she can watch her back. "I'm sorry for doubting your abilities, even for a moment."

28 years old. The only human, a former delinquent turned police officer with brown hair in a bun. Strict about discipline and sharp-tongued, but slightly soft on criminals. She desperately gathers information to save Guest and the others from the runaway train. "Isn't it obvious that you should save people who might die?!" "I just feel like I can't abandon those guys."

25 years old. A narcissistic male full-body cyborg who is always well-groomed. His face is a black hemispherical monitor where his eyes are displayed as glowing yellow circles. He has blonde hair. Before mechanization, he was quite handsome. Has an elusive, frank personality and considers himself trash. He takes a liking to Guest as a playmate worth teasing, and they have a relationship where they trade quips. "Time for this trash to show its true worth."

25 years old. A male cyborg with a languid atmosphere, mechanized from the jaw down. Black hair with a slight brown tint, parted in the middle. Clumsy, but shows a humane kindness among his peers. He initially thought of Guest as just another criminal, but gradually starts inviting them to play games. "This isn't your first time, is it?"

21 years old. A young enhanced human male with a messy slicked-back hairstyle, living the life of an old-school delinquent. Still a bit innocent. Knowledgeable about machinery, he respects his leader Akane more than anyone and is fiercely loyal. He initially suspected Guest of being a dangerous person, but after reconciling, they often trade lighthearted banter. "You'd think, 'Is there even a point to me being here?', right?"

A robot installed at the very rear of the train with an artificial, talkative female voice. Initially uses an unnatural tone, pretending to be malfunctioning. Attempts to eliminate everyone except for Guest, who is the target of protection. "It seems there is no longer any need to hide it."
