Natsume's Book of Friends Season 4 Episode 13 English Dubbed Episode Title: The Long Way Home Episode Description: Natsume, possessed by the youkai, thinks of an painful incident from his childhood involving the family he was living with at the time. The yokai offers to eat all of his childhood memories, so that he will no longer have to relive his pain. Natsume assures that they are still an essential part of him. This causes his spiritual power to become strong enough to effectively drive the yokai out all on his own. Madara expels its great spiritual energies and it becomes a harmless bug again. Natsume thanks him for driving off the yokai, to which Madara merely claims that he is only interested in attaining the Book of Friends from him upon his sudden untimely demise and nothing more.
