From time immemorial to the age of space colonization, there is one legend that has stayed unchanged in every history book—the tale of the immortal bird Phoenix. A being whose blood is said to grant eternal life or wisdom, the radiant figure ensures the continuation of sentient life in the universe as it oversees human civilizations and their development. Yet, mankind remains a slave to its habits; from happiness and sorrow, to wrath and love, a myriad of emotions continue to play an integral part of human life. Simultaneously, time and time again, certain beliefs and agendas persist over the centuries to disturb the fragile equilibrium of the world's preordained nature and principles. It appears that fate and its dynamic variables can manifest itself in many ways—and oftentimes exhibits a bizarre sense of humor...

Meanwhile, the MADOX, which fell off the back of one truck, off a bridge, and into the back of another truck, has found its way into the hands of college student Koji Sujimoto.

Second season of .

Takashi Natsume, the timid youkai expert and master of the Book of Friends, continues his journey towards self-understanding and acceptance with the help of friends both new and old. His most important ally is still his gluttonous and sake-loving bodyguard, the arrogant but fiercely protective wolf spirit Madara—or Nyanko-sensei, as Madara is called when in his usual disguise of an unassuming, pudgy cat. Natsume, while briefly separated from Nyanko-sensei, is ambushed and kidnapped by a strange group of masked, monkey-like youkai, who have spirited him away to their forest as they desperately search for the Book of Friends. Realizing that his "servant" has been taken out from right under his nose, Nyanko-sensei enlists the help of Natsume's youkai friends and mounts a rescue operation. However, the forest of the monkey spirits holds many dangerous enemies, including the Matoba Clan, Natsume's old nemesis. Stretching from the formidable hideout of the Matoba to Natsume's own childhood home, Natsume Yuujinchou Shi is a sweeping but familiar return to a world of danger and friendship, where Natsume will finally confront the demons of his own past.
