well, it doesn't have the best animation of all,I think that would be the only thing that does not convince me at all, since it does not look very fluid, except in the battles, then things change, the battles, although they are short, are enjoyable, but the truth is that it's very entertaining and the story is good. I really enjoyed it, plus the ending doesn't disappoint at all. I really like how they approach the theme of "the world changes through the actions we take". Oh, and the fact that they travel to different parallel worlds is really fun to watch. Personally, I likedthe development of the characters and the story, so if you want to kill some time, I recommend this anime.
