To be honest, this animation really got me surprised by the aspects of fighting that they have shown.
You would expect the elements of low kick, high kick and the flying arm-bar in a real life match between fighters who knows MMA, even they got the seoi-nage throws variations that the main protagonist was using to throw the intruders that got killed right, if you look close enough you can really break down each strike blows by blow, props to that.
After all it's just an opinion form me. I recommend you to watch it, if you are into fighting animations and knows some basic martials art you would definitely enjoy it.
