Reign: The Conqueror

A documentary filmmaker explores seemingly unrelated paranormal incidents connected by the legend of an ancient demon.

In 1995, a mental hospital is erected near the Japanese Ministry of Finance, located adjacent to the grave of Taira no Masakado. A young male nurse by the name of Jin’ya Yanase is obsessed with the legend of Taira no Masakado and more importantly, the spirit of his evil subordinate Yasunori Kato. Slowly, he becomes possessed by Kato's spirit, who wants to use him as a new host to revive in the modern world. Keiko Tatsumiya (the heroine of the original story), is an old woman living homeless on the streets of Tokyo. When she senses the presence of Yasunori Kato, she must regain her resolve to face the demon-god and vanquish his spirit once and for all.

A young boy with a troubled home life becomes "chosen," and he stumbles into the middle of a great war of yōkai (a class of mythological creatures), where he meets a group of friendly yōkai who become his companions through his journey. Now he must fight to protect his friends and free the world of the yōkai from oppression.

In 1945, after the horrific fire-bombings of the Pacific War levels Japan to the ground, the government consults spiritual psychics to aid them in winning the war. Unfortunately, the souls' resentment and agony of the victims culminate together to revive the evil Onmyoji, Yasunori Kato. Only a young, psychically imbued priests' apprentice will dare fight the evil magician.

Fifth grader Kei Watanabe has inherited the hunter's blood to hunt yōkai. To save the world from destruction, Kei challenges a war against the yōkai.

A demonic reincarnation of a Japanese general from the 10th century appears in the early 20th century Tokyo with a mission to destroy the blooming city.

A spiritual battle is being waged within the capital of Tokyo during the turn of the 20th century. In 1908, Japan is undergoing an enormous process of industrial renovation due the influence of radical western ideals. Technology and politics shift the country's emphasis more and more away from the traditions of the past, with Tokyo being the main center of this radical movement. At the same time, Yasumasa Hirai, an Onmyoji of the Tsuchimikado Family, has been called from Kyoto to Tokyo in order to participate in a secret meeting concerning plans to turn Tokyo into the most commercial and blessed city in all of Japan. Opposing Hirai is Yasunori Kato, an evil Onmyoji whose only desire is the complete destruction of Tokyo. Yasumasa Hirai and Kato Yasunori meet and fight for the future of Tokyo and the Japanese Empire.
