Aku no Hadou

Aku no Hadou is a prequel to Ishi no Mayu which I didn't like despite it being a WOWOW show. I can't remember anything about Ishi no Mayu and the sequel except the name Toremi so I'm going to assume the main character is him.

Aku no Hadou can be watched without seeing the previous shows because its a prequel and its a decent serial murder mystery that doesn't overstay its welcome.

Nothing fancy but nothing that I did not like. Watchable.
