Onmyou Taisenki episodes

Riku wakes up and finds himself in another part of Fukumaden. He is then attacked by a masked Toujinshi named Taishin and his Shikigami, Shousetsu no Magahoshi.

Riku and Kogenta arrive in a tranquil part of the Fukumaden. Riku feels very nostalgic about this place.

Riku has been having a lot of dreams lately, each involving a pleasant yet sad woman. When the giant Kimon in the Mikazuchi building opens, a lot of Youkai run amuck.

Kogenta is dead, and Riku has lost all of his memories from when he was a Ten-ryuu Toujinshi. So, he doesn't remember Souma, Nazuna, or the boat club.

Riku has regained his memories and is reunited with Kogenta. He also meets Yakumo again, who tells him about the Fukumaden and the past.

Riku and Souma head for the Chi-ryuu base, the main building of Mikazuchi Products. Along the way, Souma gives Riku some backrgound information on Mikazuchi, the Head of the Chi-ryuu.

Riku feels that there is no use in fighting Mikazuchi right now, so he and Souma head back to Tenjinchou on a bus. The ride home gets disrupted by a giant spider Youkai known as Tsuchigumo.

It's summer, but it's snowing! The strange weather is due to the Daikimon that the Chi-ryuu opened. Speaking of the Chi-ryuu, they have initiated more of their plans by opening the 4 Kimon.

Yakumo is attacked by Shoukaku, a Toujinshi of the Jin-ryuu, and his Shikigami, Oobi no Yatarou. Yakumo fends off the attackers and discovers what the Jin-ryuu are planning.

Following Taizan and Onishiba into a Kimon portal, Riku and Kogenta end up in Tousa of Shikoku, where a local village's crops have been growing immensely.

Yuuma must protect Mizuki while fending off two Toujinshi of the Jin-ryuu, Shoukaku (Shikigami - Oobi no Yatarou) and Zenjou (Shikigami - Tsubaki no Kantarou).

Teru needs help from Riku and the gang at the beach. There is a dangerous Youkai that eats humans, two of which are a baby's mom and dad. Since Teru is close to the parents, he grows angry.

Taizan has one of his subordinates, Murasame (Shikigami - Shirogane no Chiyorozu), set a trap for Riku, saying that his parents have been found in the Fukumaden.

Yuuma and Mizuki reach an exit from the Fukumaden, but then Masaomi appears and blocks their escape. So, Yuuma and Rangetsu will have to fight Masaomi and Kibachiyo once more.

Yuuma returns from the Fukumaden. He is offered to become in charge of the Daikimon, but he declines. Now, Yuuma and Rangetsu will have to deal with Mikazuchi and his Shikigami, Akagane no Itsumu.

Riku and Kogenta meet a Shikigami named Genbu no Koroku, who knows of a way to repair the Kotetsu sword. Riku and Kogenta also find one of the Chi-ryuu's Shikimon.

Relationships are put to the test as Mikazuchi tells Yuuma to confront Taizan and as Riku and Kogenta face the Chi-ryuu's Kureyama and his Shikigami, Enoki no Kongou.

Riku and Kogenta discover the truth about Masaomi and Kibachiyo and hear what Masaomi says about Kogenta. Yuuma and Rangetsu take on Taizan and Onishiba.

The Heads of the Ten-ryuu and Chi-ryuu, Riku and Yuuma, fight Mikazuchi in one gigantic battle.

Riku and Yuuma use their new Master Drives to fight the Itsumu-possessed Mikazuchi.
