Tokyo: The Last Megalopolis

In 1912, Yasumasa Hirai explains Tokyo's long history and warns Baron Eiichi Shibusawa that the vengeful spirit of Masakado must not be disturbed. He emphasizes that disturbing the spirit could unleash destruction on the city. Shibusawa then seeks guidance from the Tsuchimikado to bless Tokyo.

Yasunori Kato, an oni and former Imperial Army lieutenant, opposes Hirai's and Shibusawa's efforts. He schemes to awaken Masakado to destroy Tokyo and decides to abduct Yukari Tatsumiya, Masakado's descendant, to use as a medium.

Hirai's followers lock Yukari inside the Tsuchimikado temple to shield her from Kato. The Tsuchimikado perform the monoimi ceremony to keep the spirit at bay and defend the medium. The city watches as ritual safeguards unfold.

Kato and his followers launch a frontal assault using shikigami, breaching the temple defenses to seize Yukari. Masakado's spirit rejects Kato's bid to awaken him, foiling the immediate plan.

Ogai Mori diagnoses Yukari as pregnant with Kato's child, complicating the spiritual conflict and raising questions about Masakado's lineage and the fetus's fate.

Emperor Meiji dies, marking the end of the Meiji Era. In a dramatic act of devotion, Hirai commits seppuku. His sacrifice is said to divine the year of Tokyo's destruction, foreshadowing 1923.

The ritual sacrifice leads to a prophecy that Tokyo will face destruction in 1923, the Year of the Pig. The city readies for a new crisis despite efforts to protect it.

In 1923, Kato retreats to Dairen (Manchuria) and uses magical arts to generate artificial seismic waves beneath Dairen, designed to echo through the Earth toward Japan. The spell presages a massive earthquake.

Kato comes back to Tokyo intending to awaken Masakado, but is intercepted by Koda Rohan and Junichi Narutaki, who deploy the Chart of Eight Directions to trap him. The interruption disrupts his attempt at rebirth.

The seismic waves triggered from Dairen reach Japan, catalyzing the Great Kanto Earthquake. The disaster becomes a central historical turning point for Tokyo and its guardians.

Torahiko Terada is appointed manager of Japan's first Tokyo Metro Ginza Line in 1927. Hayakawa's workers seek the help of Dr. Makoto Nishimura to use his Gakutensoku automaton to aid construction.

Masakado summons Keiko Mekata, a miko, to defend his grave. She teams with feng shui master Shigemaru Kuroda who tracks the location of Kato's hideout, intensifying the dual confrontation between spiritual guardians and the intruder.

Kuroda battles an Asura statue guarding the hideout, while Keiko faces Kato and his gohō dōji minions. The two sides clash as mystic and martial forces collide.

Kato tries one last time to awaken Masakado through Yukiko, a girl born from Yukari and her brother Yoichiro. Keiko explains that Yukiko is not Kato's child and cannot be controlled, undermining his plan.

Gakutensoku self-destructs, severing the dragon vein connected to Kato's temple. Kato makes one last doomed attempt with onmyodo, but is gravely wounded. He abducts Keiko to Manchuria as the film ends, with a district festival ongoing and the Tatsumiya family hoping for Keiko's return; Kyoka Izumi predicts Kato's return.
