After five days, Yusuke was still struggling on learning the new technique. He instead constantly ended up vandalizing the dojo. "Shit!" He cried. "How hard could this possibly be?" Genkai walked up to Yusuke. "Unlike you," she began, "I've been training since I was little." "But I've been a fighter and well a delinquent since I met Keiko," Yusuke said. "Have you trained with anyone then?" "No. I was self-taught." "Looking back, you did pretty well in my tournament three years ago. I knew you had the potential to be powerful." "Right. I remembered Botan tricked me into entering your tournament. She told me I would get to go a martial arts tournament if I beat Rando." "You've always been a dimwit. But I admire you, even if you're foolish. But now, it's time to let your fists talk!"

As Rando was in the mansion's training room, he was occasionally glancing at the calendar. He had been learning secret techniques that he had recently became aware of. One new technique became one of his favorites. "Let's give it a whirl! King Fist!" Rando's body began to glow red, while he became slightly larger. This new technique, severely damaged his body. Wanting to test this new power, Rando smashed a punching bag into smithereens. "I've nearly mastered the King's Fist! Just a little more training, and I'll be unstoppable!"

Then, two days have passed, and the new Demon World Tournament was starting. Yusuke's friends were at the tournament, as part of the audience. Shortly before the first match, Keiko was dragged out by Rando, tied in rope, and the hostess of the tournament materialized. Rando has won all of the matches, until soon, the final match was starting. "Where's that black-haired brat?" Rando said. "Did he turn tail and run back home?" "No," Keiko said. "He will arrive, he will beat you, and he will save me!" "In your dreams," Rando rolled his eyes. The hostess said, "Urameshi is not here! If he doesn't arrive within the next thirty minutes, he's disqualified and that means Rando will-" "Sorry I'm late," a familiar voice said. The hostess turned around to see Yusuke. "You're Urameshi, aren't you?" "Why, yes. Yes I am." Yusuke replied. "We almost extended the deadline for you., since you were so late. Anyways, get down on the stage! Your fight is waiting for you!" The hostess said. "Alright!" Yusuke said, running on the stage. He scowled at Rando. "Rando, you bastard! Let Keiko go!" "You insignificant fool. You think I'm just going to release the girl? Not a chance!" Meanwhile, Yusuke's friends, sitting among the audience, were pondering. "Do you think Urameshi has been training hard?" Kuwabara asked. "I hope so," Botan said. "You're worried about the dimwit?" Genkai asked. Yusuke's friends turned their heads. "Fear not. He won't lose. I've taught him a secret technique."

"Begin!" The hostess shouted. Yusuke and Rando were trading blows, dodging, blocking, and finding opportunities to strike. When Rando was low on stamina, he used the King's Fist technique. "No way," Yusuke said, astonished. "Like what you see?" Rando said. "No way you'll win against me now." "We'll see about that." Yusuke used the brand new Nine Deadly Strikes technique, which sent Rando flying into through the stadium walls. "That's the technique I taught him," Genkai said to Yusuke's friends. Rando quickly got back up, though, and proceeded to beat Yusuke into a pulp. "Yusuke!" Botan and Keiko cried. "It's okay, guys, I'm fine." Yusuke was on his feet. Although he was exhausted, Yusuke fired an extremely powerful Spirit Gun at Rando. Rando retaliated with his own Spirit Gun, and the two projectiles were clashing into each other. Yusuke fired one more Spirit Gun into the one he shot, thus causing both of the projectiles to hit Rando, causing him to fall over.

Seeing that the match was over, the hostess said, "The winner is Urameshi!" The crowd went wild, and Yusuke freed Keiko from the ropes, and Keiko cried, "Yusuke! You came!" "Of course I did," Yusuke said. The two embraced each other. Botan, noticed Rando waking up, and attempting to run. "This isn't over, boy!" Rando yelled. "Oh, no you don't!" Botan yelled, knocking Rando out unconscious with a baseball bat. Yusuke and his friends then all vacated the tournament, and the Demon World as a whole, while Rando was sent to the deepest depths of prison.
