Hotarubi no Mori e, Natsume Yuujinchou Shi Recommendations
Not only do Natsume Yuujinchou and Hotarubi no Mori e have the same original creator and similar setting, they are animated by the same studio, with the same director and even the composer is the same. Without any doubt there is more than one that these two would both be liked by the same people.
The girl, Hotaru, in Hotarubi no More e and the boy, Takashi (mostly referred to by his family name Natsume), both see demon and spirits and they both befriend them. Both the film and the series play with a melancholic feeling and the relationship between humans and spirits.
