Best anime series ever ... thrilling action scenes......emotional moments ....and love ..all these elements make this series best ...I strongly recommend to give it a try coz once you start it you cant escape from it.....emotional people will literally cry while watching ....as the story is emotional and depressing too ...but I'm sure you'll feel like you are a part of this series as it's very affectionate and the action scenes will give you goosebumps which will last till the episode ends.....once again I wanna say that this is the best action series till date
