Now this is the cool anime to watch.the concept of this anime is so new that it takes you away.also the effects and the story is well maintained till the end with many twists and turns.this is one thing you would like to have in your collection.although it gets a bit boring in some middle episodes
When the main plot is driven away and some new things come up but still overall this is one of the cool anime to be watched.the effects are very nice.also each character has its own unique ability which adds on to the feature.i will give 4 out of 5 and I recommend that you should watch this anime.
