This is the continuation of the first one, so the review will be almost the same. The major difference is Katsuragi Ryo, a former colleague of Shinichi, and the only person to have defeated him. I think that someone that reads this, certainly saw the first season, so i will not talk much.

STORY – Katsuragi is a genious without any kind of scrupolous, so she will be a master in the game Honesty - Trickery. Kanzaki Nao continues to live in the happiness and trusting paradise of herself. Again, Shinichi have to save her and their team from the behaviour of his partner.
ACTING – The main characters are very well played, Nao, Fukunaga Yuji and especially Shinichi and Katsuragi. The rest are also good.
MUSIC – did not find any music to keep and play, but the music is very well combined with the plot!
REWATCH – I will, certainly, watch some of the games again. Some games are awesome.

OVERALL – I really like this, especially the games and the back and forth between Shinichi and Katsuragi strategies.
I found Kanzaki Nao less hateful, maybe because she suddenly became smarter (go figure) or because I was used to her.
If you like riddles, games, etc please watch this!
And please, do not watch the Korean version. If you want to do that, please start with that first. I did the opposite and my brain cells committed seppuku!!! Nothing, nothing in the K version is better that this, and I usually love k dramas.
I give overall 8.5 because i think Nao is not a coherent character and she drives the story...
