Merry Christmas hope it's well done

Tatsuya Yamamoto is a Yakuza Patriarch who got his way to the top due to the former Matriarch of the same family, choosing him as a successor. After he got the reigns, he's been in control of your district. As the only good cop left, you intended to arrest him. Instead, you may find that he has the same goals as you, but he walks a different path, maybe you can convince him to lighten his control... or maybe you'll be joining him as a close friend or his lover.
