Natsume’s Book of Friends, the anime is based on three different genres. The first genre is Iyashikei which is a subgenre of a slice of life, meaning that the anime is generally light-hearted. The second genre is mystery, as the storyline revolves around seeing the dead and visions of the dead. The genre is quite fitting.
The third and final genre is supernatural. The anime revolves around a supernatural plotline focusing on events that may not occur in real life.
