Gasaraki

Having obtained the location of their enemy's network hub, the Americans send 4 TAs to infiltrate and destroy it. It's up to the 3rd Experimentation Company to stop them from succeeding. Nishida's face off with the President of the U.S. comes to a close.

As Nishida's plans of retaliation against America continue to unfold, Yushiro confronts his brother Kazukiyo in regards to his ambitions pertaining to the kai.

The 3rd Experimentation Company elects to assist Nishida's ambitions. Their first task is to provide protection detail for the Prime Minister, but things quickly spin out of control.

The Gowa family puts forth a plan to search for Yushiro. Meanwhile, Japan's Prime Minister is persuaded to deploy TAs to assist in controlling an impending riot.

The flashback to the Heian period continues. Tsuna Watanabe leads his clan and his Kugai into battle against the Imperial forces as the two young kais realize they are the tools of those around them. The evil regent Einyo manipulates Tsuna into unleashing the full power of the Kugai. The willpower of Yushiro and Miharu bring an end to the impending terror, which leads to the defeat Einyo and the death of Tsuna. The new leaders of the Watanabe clan agree to bury the secrets of the Kugai and retreat back into the mists of time. In the present, Yushiro and Miharu gain a greater understanding of their place in the continuing legacy of the kai.

Freed from the Gowa compound by Daizaburo, Yushiro and Miharu resume their interrupted quest to discover the secret of their mystical kai abilities. Meanwhile, Nishida and Kuzukiyo Gowa plan a military coup that will simultaneously rid Japan of its immigrants and its avarice. In the process Nishida reveals the history of the Kugutsu, individuals who have received special talents from the lost god Gasaraki. These powers allow the Kugutsu, whose members are known as ""kai"", to operate the Kugai (plural), organic killing machines that function much like giant robots of the near future.

Yushiro and Miharu are captured by the Gowa Corporation and SSDF. While Miharu is interrogated, Yushiro is charged in trying to succeed in subduing the rogue TA pilot.

Sensing the proximity of Miharu and the other Symbol Ishtar (known colloquially as Fakes), Yushiro instinctively begins to perform the Gasara Dance. Before long, the stomach of the abandoned robot, known as the Kugai, opens up and takes in Yushiro as a pilot. The robot, adorned like an ancient Japanese samurai, battles and defeats the intruding weapons platforms and captures Miharu. When Yushiro leaves the Kugai, his master, Sorochi, informs him that Yushiro is a kai, a man with the special talent required to control the Kugai, and that the Kugai itself is a gift from Gasaraki. Sorochi says Yushiro must travel to Kyoto with Miharu in order to find out more.

Amid evidence that the Japanese government is involved in some sort of cover-up regarding the TAs, Yushiro's elder brother Kazukiyo Gowa meets with Hiraku Nishida, an elderly, blind warrior who wishes to unleash selective violence against the Japanese people in order to strengthen Japan against growing opportunism and selfishness. At the Gowa laboratory the plot takes a startling twist when Miharu breaks into the Gowa headquarters to retrieve the missing components taken by the Japanese TAs in Belgistan. As she exits the plant, Miharu reveals to Yushiro the startling secret she has uncovered during the raid - the Gowa family refers to Yushiro as ""the test subject"" and that the real Yushiro Gowa has been deceased for years. As the episode ends, Yushiro's entire existence is mired in uncertainty.

The evil organization Symbol institutes a coup in Belgistan to hide evidence of their involvement. The new leadership, lacking knowledge of Symbol's hand in events, immediately pleads for a ceasefire. Yushiro uses the opportunity to sneak deep into Belgistan and meet Miharu face-to-face, and the American government uses the pretext of weapons inspections to gather intelligence on the Gowa Corporation's bipedal weapons.

The TA units arrived in Belgistan whereupon they are ordered to capture Shrine Hill, the location where the Belgistanians allegedly detonated their weapon of mass destruction. Surprising both the multinational forces and the TA unit, researchers from the Gowa Corporation arrive and confirm that Shrine Hill is virtually identical to Stage of Stone on which Yushiro performed his initial dance. This fact is confirmed when Yushiro enters a trance mode, leaves his TA and begins to perform the Gasara dance on Shrine Hill. Undeniably, a connection exists between Belgistan's release of power and the Gasara dance.

As the Gowa Consortium evaluates the failure of their experiment with Yushiro, the United Nations responds to what seems to be a weapons test in the renegade post-Soviet Republic of Belgistan. After a successful air attack, the allied ground forces suffer a startling defeat, leading the Japanese company to reveal the secret of the Tactical Armor systems. It seems these units may have been responsible for the U.N. defeat at the hands of the Belgistanians.
