Kurayami no Ryuu wa Kagerou wo Daku

In the shadowy world of organized crime, a complex relationship between two men is about to be rekindled. Risei, a dedicated member of a powerful yakuza family, finds his carefully maintained life disrupted when Kou—the son of the family's leader—returns after years of absence. Once someone who seemed to want nothing to do with the criminal underworld, Kou has now taken on the prestigious position of Wakagashira, the family's second-in-command. When Risei is unexpectedly assigned to work directly under Kou, old tensions and unresolved feelings resurface. As they navigate the dangerous politics of the yakuza world, both men must confront their past connection and the uncertain future that lies ahead.
