Team Urameshi's successful campaign in the Dark Tournament continues after Fox Demon Kurama makes an honest monster out of Reverse Urashima. Too bad Reverse Urashima's fellow Fractured Fairy Tail Shishiwakamaru silences him before he could divulge the truth about their team.

The Dark Tournament is finally down to the wire. After a long trail of brutal bloodshed, the stage has been set for the ultimate showdown between Team Urameshi and Team Toguro. And now that Kurama can transform into a fox demon at will by drinking the potion from the Seed of De-Incarnation, his ferocious plants have been given a much-needed energy boost.

When Kuwabara learns the truth about Genkai's demise, he takes the news hard, wondering why Yusuke waited so long to tell him. Then the elder Toguro reappears and taunts the team about Genkai's death! It's not a good idea to tease those experiencing great sorrow - a lesson the elder Toguro quickly learns, but not from the one you'd expect to teach him.

After the Dark Tournament ends Yusuke and friends come home for a much deserved rest. The vacation is cut short when Yusuke gets taken hostage by three classmates who have recently gained strange powers. It's up to Kuwabara and friends to try to rescue him. But without their star fighter's abilities will they be up to the task?

With the Dark Tournament far behind them, the gang is in a whole new mess! Someone is trying to pick up where Sakyo's dream of opening a portal from the demon plane into the human world left off. Already, energy from their evil world is seeping through. The group heads to Swarm City and finds the place crawling with nasty insects only those with a developed sixth sense can see.

Kuwabara's been kidnapped! Unbeknownst to anyone - especially him - his aura sword is so powerful it can actually cut holes between dimensions, which is exactly what his kidnapper Sensui is after. But Yusuke's not giving up so easily and sets off in pursuit on a bicycle.

Itsuki locks the others away in a separate dimension so Yusuke and Sensui can fight undisturbed, and under intense pressure, Sensui's real personality, suppressed for so long, starts to come out. Then Koenma shows up and things really start to get hot, and Yusuke has to resort to desperate measures to draw their enemies out.

Yusuke and the gang finally face off against Sensui in a final battle to defeat him and close the portal to the demon plane. The furious exchange of devastating punches and reigun blasts push both Sensui and Yusuke beyond the limits, setting off a transformation that no one, least of all Yusuke, ever expected!

After the epic struggle to close the tunnel to the demon plane, Yusuke and the gang take some hard-earned time off. It's still a busy year, and Hiei and Kurama both spend time training and taking care of some loose ends from their pasts. Meanwhile, Yusuke trains with Raizen and ends up in charge of the old demon's domain!

The tournament to decide the ruler of the Demon Plane reaches its final rounds and you won't believe who comes out on top. But Yusuke and the gang still have a few loose ends to tie up, as they have to make sure the denizens of the Underworld don't get too far out of line. Later, everyone heads out to the countryside to hear a final message from Genkai. And then...

It was a typical day for Yusuke: go to school at noon, get kicked out by the teacher, fight with his rival Kuwabara, and head for home in time to wake his mom from her drunken stupor. But when he throws himself in front of a car to save a little kid's life, he becomes Tokyo's toughest teenage ghost!

Yusuke has only one day in the real world before he becomes a ghost again, and it ends up being the day a thug from another school kidnaps his girlfriend Keiko. But how can he rescue her without letting her know he's alive? When she's trapped in a burning building where his own comatose body lies, Yusuke faces a terrible choice...
