This is such an out-of-the-world, completely original storyline, that I will always remain impressed with. The story revolves around Fushi - an immortal being, who learns and grows from experiences and relationships with others. Season 1 had me crying nearly episode, while in season 2, we see a more humanly-developed version of Fushi, who strives to make good friends. It was heart-warming seeing the people who care about Fushi, albeit some in a near destructive way (aka Guardians), and we get a special character (Bon) who literally is the linchpin of this season. He was able to understand and communicate with Fushi like no others could, exceptFushi's old friends in S1, and always gave him support when he needed it.

Overall, this anime is just a really really good-watch, and it won't be like any other that you know
