episode 9:

The biggest plothole in this story is how the Yakuza apparently don't put the wife under surveillance AT ALL. All the plans only work because she's able to move freely lol.

On the episode: I don't quite understand Tetsuo's choice to have Kyouichi killed. Aren't the other yakuza much more likely to get rid of him and possibly his entire family after the murder case is cleared? Doesn't matter who did it, but at least Kyouichi seemed to be someone who could be convinced to let Tetsuo live, while Takeda and his group's boss don't give a shit.
