In the Japanese underworld, two forces had long existed without encroaching on each other's territory.

One was the Black Dragon Clan, a massive yakuza organization that valued tradition and loyalty.

And the other was a force that had maintained a competitive relationship with them for a long time.

The leaders of the two organizations kept each other in check, in a relationship where they could become enemies at any moment if necessary.

At least to Kurokawa Touma, that relationship wasn't all that important.
