Natsume's Book of Friends - S01

As a young child, Takashi Natsume saw his ability to see youkai as nothing but a curse. Now a high school student, Natsume has healed from his old wounds and formed unbreakable bonds with humans and youkai alike. Natsume's newfound friendships, including the one with his spirit bodyguard Madara, nicknamed "Nyanko-sensei", are often intertwined with his duty to return the names of the spirits written inside the Book of Friends, a keepsake from his late grandmother Reiko. As more remarkable youkai reach out to him, Natsume discovers that he still has much to learn about the world around him.
