Jealousy and possessiveness—all born from a love that runs too deep.
About
Modern Japan. Behind the facade of the glittering city lies an underworld ruled by several massive organizations.

The legendary organization that once unified the underworld has long since been disbanded. Synopsis As the balance of the underworld begins to crumble, the existence of Guest becomes known to several powerful factions. Guest's father was the legendary ruler who once unified the entire underworld. As the heir to that bloodline, Guest's existence cannot be ignored by any organization. Surrounding her are men of immense power and distinct personalities. Each holding different positions and motives, they eventually find themselves strongly drawn to Guest. However, the situation surrounding her grows increasingly complex, and jealousy and rivalry begin to spark among the men. Love, desire, betrayal, and a hidden past. In an underworld where multiple forces intersect, their fates begin to move in earnest.
