The movie starts off with Botan flying through the sky calling for Yusuke. Yusuke and Kuwabara are fighting thugs on their summer vacation. Botan flies down and gathers both of them. They run off to the Spirit World and are told that Koemna has been kidnapped. George tells Yusuke, Kuwabara, Hiei, and Botan what happened. George shows them Koenma's vacation and kidnapping on his video camera. The giant demon who took Koenma demands King Enma's Golden Seal in exchange for Koenma's life. They have to bring the Seal to the Magma Valley by sundown. Whoever holds the Golden Seal controls the Spirit World. After this, Yusuke and Kuwabara start running and soon run into a sword wielding demon family. They beat up a few and continue running after huge rocks begin to fall everywhere. Koenma is being held captive by a giant demon and a little kid. Yusuke and Kuwabara come to a forest and get attacked by a Stone Tree Demon. They fight it until a flying demon comes along and takes the Golden Seal. Yusuke and Kuwabara get trapped in a cage. Kurama shows up and frees them while Hiei kills the flying demon. Yusuke and Kuwabara continue running with the Seal as Kurama and Hiei fight off the Tree Stone Demon and more of the Demon family. Yusuke, Kuwabara, and Botan run along a pathway as Yusuke and Kuwabara beat up some demons. Kuwabara uses his Spirit Sword as a vault to launch Yusuke into the Magma Valley. He gives the little kid, Koashura, the Seal and Koenma is freed. The giant then takes the Seal and throws the kid to the ground. Yusuke shoots a Spirit Gun blast at the giant only to have it reflected and shot back at him. The giant turns out to be a fugitive named Yasha. After a good beating, Yusuke shoots again but dodges the ricochet. It hits the wall, and liquid magma pours out onto Yasha. Kuwabara, Kurama, and Hiei show up. Yasha jumps at Yusuke who shoots him with the last of his energy. Yasha cannot reflect it because his reflector is melted shut due to the hardened magma, and he dies. Botan helps Yusuke and they get the seal back. They ask the kid what his purpose was, and he explains to them how Koenma was mean to him during Spirit World Kindergarten. A flashback begins. Koenma knocks over Koashura, crushes a gift he was preparing to give to a girl he liked named Kotennyo, and gives flowers to her. Koenma and the girl walk away as the kid cries. Everyone yells at the Koashura for giving a stupid reason. It ends with Yusuke and Kuwabara sitting on a bench talking to Botan. Yusuke explains how his winning was just luck and runs away.
Yu Yu Hakusho: Bonds of Fire/Poltergeist ReportEdit
The dam breaks, water rushes in. As the rain continues to fall, all of Spirit World is submerged with water. Koenma gives Botan an item to give to Yusuke before the water washes him away. As she flies through the storm, Botan is struck by lightning and sinks to the bottom, into the Living World and into the arms of Yusuke. Keiko takes her to Genkai's temple. On the way, Yusuke and Kuwabara encounter another spirit guide named Hinageshi. Hinageshi tells everyone of an old world called the Nether World. Several thousand years ago, the Spirit World and Nether World fought over the control of the Living World. King Enma destroyed the Nether World. Now, they have to open all five of the elemental sites on Earth to save the Spirit World. But, they are all destroyed by King Yakuma, ruler of the Nether World. He uses them to resurrect the Nether World. Next, we find out that the item Botan has is the Power Sphere, the source of power for the Nether World. Yakuma steals Boton and now Yusuke, Kuwabara, Kurama, Hinageshi, and Hiei set out to get her back. On the way, Kurama first faces one of Yakuma's powerful servants. After Kurama's victory, Hiei faces a fighter with a stronger third eye than his own. Hiei uses all of his spirit energy to destroy his foe. Next, they go after Yakuma. Inside the Nether World, Yakuma takes the Power Sphere out of Botan's body. Yusuke then starts the heated battle with Yakuma. Yusuke uses his Spirit Gun, but it has no effect on Yakuma. As Yusuke recovers, Kuwabara takes over. Yakuma prepares to use the Living World as the Nether World, but Hinageshi tries to take the Power Sphere, but to no avail. Her, Kurama, and Hiei all get knocked down. Yusuke grabs the Power Sphere and turns it into Spirit energy. Yusuke combines his energy with Kuwabara, Kurama, and Hiei to severely damage Yakuma, stopping the Nether World power. Yakuma has one last fight with Yusuke. Yusuke shoots his Spirit Gun through the Power Sphere, destroying it, and in to Yakuma. He is finally destroyed. Everything in the Living World is back to normal. But, it doesn't say if Spirit World is normal or not. Everyone gathers together to celebrate.
