I started out with the anime not know anything about it, and I must say that I fell in love with Fushi and everything about the plot and concept. It has many plot twists, and the readers never really know what will happen next. It's so fucking sad, and I've cried my eyes out many times. Some people think being immortal is one of the best things that could ever happen (in terms of superpowers), but this manga really shows how lonely everything gets at some point.
