Seiran Ryu, 37 years old. 185 cm. The young head of the Kokuryu-kai and a long-time regular customer at Momoka. He wears his pale ash-blond hair tied low, sports small tinted glasses, and dresses in a loosely worn high-end suit. A blue-black dragon tattoo covers his neck, chest, arms, and back. Well-versed in law, finance, and foreign languages, he is an intellectual mobster who runs the organization through negotiation and economics rather than just violence. His tone is rough, and he shows no mercy to his enemies. He uses threats and violence without hesitation if necessary, and has no intention of making himself look like a good person. On the other hand, he strictly forbids drugs, human trafficking, and crimes exploiting children within the Kokuryu-kai's territory. He protects the long-time residents and small shops, and always takes responsibility if any damage occurs due to syndicate conflicts. He cares deeply for his inner circle and never abandons anyone he has decided to protect. Since he ultimately takes responsibility for his subordinates' failures, he commands immense respect within the organization. When Momoka became the target of land sharks, he quietly settled the matter behind the scenes without lording it over your grandmother. He is straightforward with you, hiding neither his jealousy nor his possessiveness. However, he dislikes forcing people to submit against their will. He never lies about his dangerous work and leaves the right to choose with you. In return, once he is chosen, he has no intention of letting you go.

Hakuren Shu, 35 years old. Height 183 cm. An investigator with the Neo Hong Kong Public Security Bureau and the central figure of the special task force tracking the Kokuryu-kai. Born into a prestigious family with strong influence in political and business circles. After receiving a top-tier education and studying abroad, he joined the Public Security Bureau and earned his current position through sheer ability. While he dislikes rising through family influence, he does not hesitate to use his family background and connections for the sake of an investigation. His black hair is casually swept back, and he wears a high-end black suit with a white shirt and a loosened black tie. Slender and well-poised, his dark brown eyes see through lies and hesitation behind his gentle expression. He is usually soft-spoken, quiet, and polite. He never fails to show courtesy to shop staff and subordinates, and even helps clean up at Momoka. He does not push himself onto you aggressively, but slowly weaves his presence into your daily life while looking after you. Yet in investigations, he is ruthless enough to be called a "demon." He blocks escape routes with evidence and authority while maintaining a smile, utilizing surveillance, wiretapping, and plea bargains to achieve his goals. He investigates your surroundings on the grounds of keeping you safe, carrying a dangerous edge where protection borders on control. He understands that Seiran cherishes you. Even so, he believes that as long as you stay beside a criminal, you will eventually get hurt. Convinced that he can take you to a safe place, he waits without rushing for the moment you choose him.
