This animation is great, so I will spill out my only complaint about it first, so that I can talk mostly about how good this is. So, the voice audio was a bit on the bad side, not much, but it seemed a bit off at parts.
To the things I liked. Firstly, the character design is amazing, not only the two main characters, but also all of the background ones. Everyone has details that make them look genuine. Also, this goes beyond just the visual design of the characters. They have interesting and clear personalities that make them a lot more relatable to.
The action scenes are quite good and fluid, even if they may seem a bit too fast paced at times (which may make them get a bit confusing).
The idea of the plot is also nice, and taken lightly, which is good, as a theme like this one is usually approached in a very serious manner.
