The Great Yokai War
A young boy named Tadashi Ino moves to a small town after the divorce of his parents. At a local festival, he is picked to be that year's "Kirin Rider," a protector of all things good. He soon discovers that his new title is quite literal, as a nefarious spirit named Yasunori Kato appears. Originally a human who became a demon from the strength of his hatred for humans, Kato desires vengeance against their actions on the Youkai. To carry out his revenge, Kato allies himself with a Youkai named Agi while he summons a fiery spirit called Yomotsumono, composed of the resentment of the many things which mankind has discarded. With Yomotsumono's flames, Kato feeds it Youkai which are used as ingredients in creating violent junkyard Tsukumogami under his control that capture other Youkai to build their numbers while killing humans. One of such Youkai, Sunekosuri, escaped and befriended Tadashi who attempts to obtain the Daitenguken from the mountain as part of being the Kirin Rider. However, he wimped out at the last second and with trickery by Shōjō, who picked Tadashi out, the boy overcame the test. Accompanied by Shōjō, Kawahime, and Kawataro, Tadeshi makes his way to the DaiTengu who gives him the sword before being taken away by the Tsukumogami. In spite of Tadeshi's attempts, the sword is broken as Agi takes Sunekosuri as her captive before the boy is knocked unconscious.
When the boy comes to, he finds himself among Youkai as they discuss how to fix the Daitenguken, deciding to get the aid of the blacksmith Ippon-datara. But learning he was also captured, General Nurarihyon and his group leave with Kawataro restraining an Ittan-momen while praising Azukiarai, unaware that he only remained behind due to his foot getting numb. When Kato's industrial fortress takes flight towards Tokyo, Tadeshi and company pursue and arrive after the fortress ingested Tokyo's Shinjuku Capital Building, finding Ippon-datara who reforges the sword while avoiding how he escaped thanks to Sunekosuri who took his place in becoming a Tsukumogami. Donning new attire, Tadeshi and company are outnumbered until they receive unlikely aid from thousands of Yokai who believe it's a party as their festival brawl with the Tsukumogami allows Tadeshi and Kawahime to enter the fortress safely, followed by a Youkai-obsessed reporter named Sata whom Kawahime saved in the past.
Forced to slay the Tsukumogami that Sunekosuri became, restored to normal yet hanging on for dear life, Tadeshi battles Agi in rage before she is called back by Kato to begin the final phase by joining with Yomotsumono. Despite Tadeshi's attempts, Kato proves to be superior as Kawahime attempts to protect the boy, admitting to her hatred for humans for being abandoned when she first came into being, but will never resort to a human emotion like revenge. Unphased, Kato takes the two out as Azukiarai awkwardly arrives and the villain calls Agi to join him. However, because she loved him and thus a hindrance, Kato kills her instead before entering the oven to become one with Yomotsumono. However, due to Sata's actions, one of Azukiarai's Azuki beans ends up in the mix with Kato, causing a chain reaction of positive emotion that destroys Yomotsumono. After the Youkai take their leave, Tadeshi and Sata find themselves on the street as the boy tells his first white lie to the reporter about Kawahime's feelings towards him. Years later, Tadeshi is a grown man who lost his ability to see the Youkai, even Sunekosuri who is confronted by an Azuki-pupiled Kato.
