This is also all of my opinions. Do not be affected by my own rating as we all have different entertainment values.)

I never knew I'd love a series so much. I already favoured Girl From Nowhere season one but season two brings so much more. I personally prefer season two over season one. Season one lacked the main conflict (which is pretty understandable). Each episode was different and had no connection to the last but that's what I loved about it. Season two was much more flavourful, in terms of writing, cinematography and even acting. I admit I was a tiny bit hesitant watching season two thinking it'll be similar to season one but it wasn't.

In terms of each episode, I do have to warn you that this is gore and it is not for those who don't like blood or anything gory, guns, suicide, body anatomy, r@p3 etc...
Now, even further warnings: Episode two is light and nothing like you'd think (happy ending? surprisingly yes!) but it goes all dark in episode three. Episode five is probably the most disturbing of them all but the rest is similar (in terms of content) to season one.

I'll start with the individual episodes. Each episode brings their own messages and consequences of their action. The acting portrayed by everyone was amazing and the music is suspenseful as always.

This season brings such a powerful message that even those who seem on top can topple down. Nanno, probably the strongest and untouchable character I've ever seen in any drama, has NEVER shown any vulnerabilities in season one but it all changes when a mysterious girl with a red ribbon 'sabotages' her plans.
I've never seen Nanno so scared of her own creation and with that information itself (Kitty's acting is no joke, it's amazing how everything feels so natural), we know that it was a foreshadowing of what was going to happen to her.

I'm so glad we got to see another side of Nanno, being vulnerable and cautious around Yuri but showing her she was still the boss was just amazing. The range in Kitty's acting is standing ovation worthy. Nink's portrayal was also amazing!!

I loved Yuri and Nanno's dynamic relationship. They both had the same end goal but they approached it differently, you could tell Nanno was the professional one compared to Yuri who seemed new (she was impatient with Nanno's ways which could also be a foreshadowing of Nanno being slowly replaced). The two were like Yin and Yang—it depends on you who you think is the Yin and Yang.

I will also admit I was hesitant of Yuri's appearance, it shook me as well mostly because I loved Nanno the way she was. I wasn't sure if I was going to enjoy another, 'Nanno' but to my surprise, Nink portrayed Yuri so well.

But my point is, even the devil is scared of its own creation, knowing that whatever they created is their downfall. Nanno reviving Yuri. Controversial but maybe Nanno knew what her end game was. Why else would she create a person like her if she doesn't know what her fate is?

Now that all of that is said, I do highly recommend this. No, I don't think you necessarily have to watch season one but it'd give you the background information on Nanno and how far she can go.
