It's been a peaceful 25 years since the dark tournament incident, and our heroes have been resting peacefully. Keiko and Yusuke have been married for 20 years now, and are celebrating their anniversary in the mountains of Osaka. Kuwabara married his long-time girlfriend whom he met a couple years after the dark tournament. She is a psychic name Madison. They live in an apartment with their 2 kids, Akira and Sakura, both can move objects with their mind and Akira can predict the far, far future. Hiei and Kurama came to earth, got married as soon as they could, and now live in a nice house just outside of Hong Kong. Yep. Everything is peaceful. Or is it?

"AAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHH!" The cries of young women echoed through the empty valley like a ripple of water moves through an empty pond. Her soul was being ripped out of her body by what appeared to be a snake. But this snake wasn't like any other snake. Along its back was a picture of a dead woman on a canyon floor. This was her fait. But what was this snake? It was not from earth. That was certain. It seemed to be laughing. THUMP! The lifeless body dropped to the ground as if it had been thrown there by some despicable being. The snake grew bigger, and bigger, and bigger. It started to take the shape of a human being. Finally the transformation was complete. He had torn cloths, and long, dark hair. There was a menacing look on his face.

"HUNNY, DO WE HAVE ANY OTHER THINGS THAT NEED WASHING?" "NO, DEAR!" Yusuke and Keiko were having a wonderful time in the Osaka Mountains. They were approaching their last month there, and today they were taking it easy and doing some clean up around the cabin. While Yusuke did the dishes, Keiko was doing the laundry. As Keiko was just about finished loading the laundry, she felt a presents behind her. She quickly turned around. "HELLO!" "AH!" There stood Botan, happy as could be. But the news she brought wasn't nearly as happy or joyful. She explained to Yusuke and Keiko that a new evil was wreaking havoc in the spirit world and only if the 4 greatest fighters in the galaxy could stop him. "We need your help, Yusuke. King Yama is furious. Koenma is trying to get things straitened out, but that's only making things worse. This evil has the power to take any shape he wishes, and has the capability to destroy the universe and the spirit world as we know it. It sucks the spirit out of any living object, and uses it to become stronger. It can also read minds, so it knows its opponents next moves, and it can move so quickly, it appears its teleporting. The others have already been notified. Yusuke, the fate of the world rests in your hands.
