What ruins this anime a bit for me is the overhyped and story pacing.
I've heard a saying that "Seeking revenge is to dig two graves." and this anime serves that well. Perhaps the concept that revenge is meaningless but sometimes needs to be dodne for jusstice is also appropriate.
The first 3 or 4 episodes are okay. I'm into true crime podcast so watching this series is interesting for me. The plotting and the schemes although a few seems like unreasonable and impossible most of the schemes are realistic. I say they are unrealistic as it just favors the MC alone most of the time.
The side characters for this anime are like a plastic cut out simple minded characters that can't even think some true logic despite being in the higher ranks of mafia. It feels odd.
Needless to say this anime is not for me but for some, they might enjoy it as this series only have 12 episodes plus a bonus 13th episode.
