Another great drama from the Murder Analysis Squad series. Have to say that the very moment it was indicated that the series will be focusing on Toremi/Yaginuma Masato prior to events in Ishi no Mayu I'm already looking forward to this series.

Considering the events in Ishi no Mayu and Suishou no Kodou, we as a viewer had been given lots of glimpse into Masato's past and the case that changed his life forever. Given that kind of past and complicated relationship with Kisaragi Toko, there was still a lot of things that were not known about Masato. Not to mention that despite his criminal ways, Masato still retained some kind of values and had stuck with it throughout the last two series. And I'm glad to have Aku no Hado revealed the events that occurred a year prior that jumpstarted the path that he ended up taking during the course of Ishi no Mayu.

If there's anything I'm dissatisfied about this series would be, I wished there'd be more callbacks to some of the key events in Ishi no Mayu. As well as what ended up happening after the 2014 serial murder was solved and how the case was handled that would have elevated the distrust Masato already have towards the police force.
