The animation looks really good except for some weird angles from swords and things. If you pay close attention you can see that it is slightly flawed but aside from that it looks great and combat when it is around, is entertaining and pretty legit.
The sound and music is solid. The characters get along really well and are pretty well thought out. The story starts out confusing because it starts near the end and then backtracks which is really the best way to handle what happens. It is done well.
There are a few moments that make no sense. At one point a character comments on the unnecessary movements they had in battle even though they were fighting something that was mimicing them, which is really the only situation where this statement could be flawed. Another example is it is mentioned that one of the characters has advanced techniques with battle however these techniques are never mentioned before or after this converstation and are never seen.
Overall it is actually really good. The characters all get along in differnet ways and feel very lifelike and are consistany throughout the whole show. They are actually just as interestaining as the combat and action, which really gets the viewer pumped.
8.5/10 Solid stuff!
