Still fighting Sensui...
Koenma fell to his hands and feet and said, "It didn't work. How did it not work?"
Sensui said, "Your powers don't work against sacred energy. What a waste of your royal saliva." He threw the pacifire away.
Yusuke stood up, his shirt torn off and his jeans a wreck. He said, "Alright Sensui, I've got a plan and I know, you know, I know what I'm thinking."
Kuwabara shouted, "Urameshi wait!" He tried to power up his new spirit sword but nothing happened.
"You're still pathetic," Hiei shouted, "would you hurry up already?"
Kurama said, "Patience, Hiei."
Kuwabara shouted, "Don't do it yet, no! I have the power we need, we all know it!" Sensui proceeded to beat the crap out of Yusuke. "You've played your part, now it's time for me to play mine!" He tried again but only his normal spirit sword appeared.
Right when his spirit sword did appear, he cut down the shadow creature and Yusuke was stabbed in the heart by Sensui. He died instantly.
Kuwabara, Kurama, and Hiei are now by Yusuke's dead body just as the hole to demon world opened.
Kuwabara said sadly, "I knew he was going to do it but it's still painful to watch him dead right there."
Kurama replied, "We shouldn't use up our energy for no reason."
Hiei said, "Do whatever you want, I'm still going back to demon world." He started charging toward Sensui.
Kurama turned into Yoko Kurama in outward appearance and said, "Of course." He followed Hiei.
Kuwabara shouted, "Guys wait for me! I'm coming with you." He ran after them.
Hiei shouted, "Here is a one way ticket for you straight to hell you bastard!" The dragon of the darkness flame came out of his arm and attacked Sensui while incinerating every other demon in the area. They all followed him to demon world.
Yusuke is back from the dead and he flew to demon world on Puu with Koenma. Hiei, Kurama, and Kuwabara were completely out of breath from fighting Sensui.
Yusuke asked, "What the hell you guys, you knew I was coming back this time you didn't have to use up all of your energy to try and avenge me or whatever."
"He still killed you," Hiei replied, "that alone deserves death."
"Well now that I'm one of those S class demons again it times to kick some ass," Yusuke replied, "now it's just me and you, well, me and you, and you, and you, and you, and you, and you, and you. Let's finish this."
The fight went exactly the same way.
Itsuki came and took Sensui's body away.
Yusuke said, "Screw you, Raizen I could have won that fight!"
Kurama replied, "You'll have to tell him that in person later."
"What are you talking about?" Koenma asked, "How can you be so sure Raizen is Yusuke's ancestor?"
Kuwabara replied, "We don't, just a lucky guess. Haha. We should get back to human world, okay? Look, Hiei's already passed out." He looked at Hiei sleeping on Puu.
"Load up Puu," Yusuke said, "we're going home."
