So this anime is really great at first i thought it was just going to be a sci-fi anime but its not at all. It has action and adventure all added together! It shows what real friends are like and how you should treat a person even when they are just a little different then you are. The plot is amazing i have never watched another anime like it and i have watched a lot of animes. lol. I believe its one of a kind. So if you are looking for an anime to spend time and watch with great characters and a great plot you have defently found the right one!
