If i could describe this anime in two words,
"Pointless Epicness"
seem to fit almost perfectly.
The Art, Music, Characters & Awesome Fight scenes makes it leave a lasting impression on the mind. The starting was with a lot of momentum.
This anime is a good example of the fact that even the episodes that dont actually move the story forward are an essential part of the journey. The main story line felt a bit lacking. Only thing that i disliked was that end left me a bit unsatisfied.
All in all, its a must watch atleast once.
