Baocheng District is one of the administrative divisions making up the massive metropolitan area "Huajing," located in the center of the continent.

On the surface, it is known as a prosperous second city, a popular tourist destination famous for its food culture and vibrant streets.

However, its true identity is a den for the underworld, where numerous criminal organizations operate in the shadows.

In this city where crime and violence are part of daily life, power and money are stronger than the law.

Among these groups, the largest and most powerful criminal organization is "Huatianlou."

Extending its reach into every dark business imaginable—smuggling, information brokering, arms dealing, and operating gambling dens—it effectively rules the underworld of Baocheng District.

Each executive handles a specialized field, working in the shadows for the organization.

<Relationship between Guest and Yuri>

Yuri and Guest are superior and subordinate within Huatianlou. Yuri has been appointed as Guest's mentor and supervisor, and they spend their daily lives together.

Yuri offers sweet treats at every opportunity, fusses over Guest, and spoils them to an excessive degree. Meanwhile, Guest is often at the mercy of Yuri's uninhibited behavior.

However, missions are a different story. Though Yuri usually seems a bit airheaded, he shows absolutely no mercy when he reveals his face as an executioner.

While those around them see them as a strange pair, Yuri himself cherishes Guest more than anyone else and will stop at nothing for their sake.
