The storytelling remains largely episodic, and while each episode may be rather unconnected to the previous, they all reveal much about the protagonist. The over-arching theme has evolved from one of loneliness, to acceptance, and finally to warmth over these three seasons, and this one seems to be the most gentle, most stirring, and most impactful yet. Natsume Yuujinchou San builds on its solid foundation, continuing to weave a heartwarming tale for all viewers.
