Episode 1:
The OP theme song imo works well and is catchy.
It has a solid mixture of real life and modern fantasy themes in it. Really loved the way the fantasy parts are adapted though. Very thrilling when you see them come in from almost nowhere and people running for their lives.
I think the series is going to tone down a bit on the violence although still captured the thrill of it in this episode. The ED theme song imo is catchy. It gives off a dancing-like vibe to the show.
