Just keeps getting better and better

So now Sawatari wants Kurokouchi to join the Sakura Fubuki association? I don't think he's stupid to let him join in while he was the one who killed his woman. I also don't believe that the whole Sakura Fubuki is evil. Sawatari could be evil because he killed many people but I don't think the same goes for the association.

Takashi almost confessed and I am pretty sure that Shiroo dude from the past was the one who helped him, is he really dead like Endo stated? I also felt bad for Endo, he didn't want his friend's daughter to get hurt.

Let's see where the writer's hypothesis of a real unsolved case will lead us to.
