I made the same mistake again... Bullets pouring down like rain! Love for Akino running through! Shinsengumi division! Kisu-gumi plotting assassination!

Shizuya, who appeared on the first anniversary of Ken Sakamoto's death, the fourth Kishu-gumi. He again asks Ryuko to accept the sake cup. What about Shizuya and Ryuko? On the other hand, Shizuya, who went to see Akino after studying abroad in France, was frustrated by his gangster side...

Kishu-gumi and the Hong Kong mafia will die in a trap set up?! Can Shizuya save this desperate situation?!

Shizuya thought that he had won the deadly battle with Kaifu, the fifth generation of Kishu-gumi, and put an end to the long-standing conflict, but the tenacity of Kaifu's overthrow Shinsei-gumi does not change even in a dying state.
