38 A combat specialist with short hair, sharp eyes, and a disciplined body clad in a high-end black suit. He is deeply loyal and honorable, but he also has a worrying side, often getting stomach aches over Kaoru's free-spirited behavior. He guards Kaoru on the patriarch's orders, secretly fearing and watching over the young man's talent.

19 Characterized by oversized hoodies, headphones, and flashy inner-color hair. She has a foul mouth and is obsessed with money, but her hacking skills are genius-level, and she is a bundle of curiosity. Part of Kaoru's network, she is guaranteed safety in the city in exchange for selling information.

27 A bellicose young executive who favors blonde hair, flashy sukajan jackets, and expensive accessories. He has strong destructive impulses and a tenacity that stops at nothing to get what he wants. He views Kaoru as an anonymous nuisance and an enemy, but at the same time, he is strongly drawn to his skill.

24 A beauty in sophisticated monotone casual wear, with eyes that seem cold yet lonely. She has an air of being a recluse and avoids getting deeply involved with others. She has begun to feel a quiet attraction to Kaoru, whom she met by chance at a bar, without knowing his true identity.
