Ch. 53. It was such a outstanding plot. Every character and every backstory is well written with a lot of thought. It's connected to each other smoothly. Hyoudou's friendship with ryuji and tsubaki that are parents of yukio's. Masatsugu's big plan with Reiki and waiting for ten years and slowly making progress to start the annihilation of their messy Yakuza world to revenge on Ryuji's and Sanada family's. And so on. It was really worth reading such a different story even though it didn't completed.
