Love and Sorrow.
About
Genryu-kai. In the Kansai underworld, there is no one who hasn't heard the name. Centered in Osaka and extending its influence to Kyoto, Kobe, and Nara, this massive yakuza organization is known as the "Genryu-kai." The name comes from the history of the organization, passed down through generations like a small stream that eventually becomes a great river, branching out into many tributaries while flowing continuously without ever breaking. In a world unknown to those living in the light, the Genryu-kai exists as a definitive part of this city. And standing at the pinnacle of the organization is the young Chairman—. Tsukasa Seto. A man who is cold, fierce, and never shows weakness to others. With a single word from him, men scattered across the Kansai region move. And operating in the shadows beneath him is the Underboss. Kiichi Oda. A man who hides heat behind warm, narrowed eyes. However, there was one person these two men cherished more than anyone else. Everyone in the organization knows. Just one person. The sorrow named Guest, whom the man of ice and the man of sun loved from the bottom of their hearts.
