Luna, Kay, Honda, Mokuba and Anzu ran to his fallen body as his form appeared on one of the stone carvings.

"Another soul, another step closer to awakening the great beast." Dartz said, laughing.

"This ends now!" Yami yelled at Dartz.

"You're right." Dartz said and drew a card. "Once I play this card, you and Kaiba's fate will be sealed. The Seal of Orichalcos is about to become even stronger. It's time to experience the third level of darkness!" He played the card and a third layer formed around the seal.

"How could the seal possibly get any stronger?" Yami asked.

"You're dealing with a force greater than the darkest shadows. And older than time itself." Dartz answered.

And due to the effect of the card, Dartz's life points shot up to 18,500!

"His life points are out of control!" Kay cried.

The duel continued on.

Dartz attacked Yami with the Mirror Knights, and he had no monsters on the field to protect him.

"Because of the third Seal of Orichalcos, the Mirror Knights cannot defy me." Dartz said.

Yami then got struck by Yugi, then Cat, then Mai, and then Joey.

"How does it feel now that they're on my side?" Dartz asked Yami.

Yami grimaced in pain.

Finally, Mirror Knight Pegasus attacked.

Yami raised his duel disk as a shield to intercept Pegasus's sword…but then…Pegasus paused before him.

Yami became surprised when Pegasus leaned in and spoke. "Please tell me that you still have that card I gave to you. That card unlocks the secret of the Legendary Dragons."

"Attack, you fool!" Dartz shouted at Pegasus, and Pegasus did so.

Everyone watched Yami as he was sent to his knees by the attack.

"Get up!" Kaiba ordered Yami.

Yami struggled to his feet. "I'm fine…thanks for asking." Yami said to Kaiba sarcastically.

After a moment, Kaiba was able to summon Critius.

"If I know your gaming strategies as well as I think I do, your face down card is Mirror Force." Kaiba said to Yami.

"That it is." Yami agreed.

Kaiba revealed Yami's trap card and merged Critius with it to form Mirror Force Dragon.

"What do you plan on attacking?" Yami asked.

"You know as well as I do that there's no way we can win with those Mirror Knights on the field." Kaiba said.

"No!" Yami said to him.

"They're just holograms! Dartz made them look like your friends so you'd be afraid to attack! But I'm not!" Kaiba insisted.

He then ordered Mirror Force Dragon to attack Pegasus.

"Why did Kaiba attack the one Knight who still has his mirror shield?" Honda asked.

"Seto wanted the Knight to reflect his attack." Mokuba said.

"I now activate my dragon's special ability! It will absorb the reflected attack and it will be sent back, destroying all five Mirror Knights!" Kaiba said.

"Don't do it!" Yami cried.

"If the five Knights are destroyed…does that mean their souls will be lost forever?" Luna asked.

"We're about to find out." Dartz said.

"I'm not as gullible as the rest of these dorks. You can't fool me with a couple of reprogrammed holograms. I invented this technology." Kaiba said.

Kaiba then ordered his Dragon to go ahead.

Yami tried to step in.

"Relax." Kaiba simply said.

"Yugi! Cat!" Yami cried.

Yugi smiled. "Don't worry about us." He said.

Cat smiled also. "We'll be fine." She said.

Pegasus grinned at Kaiba. "Kaiba-boy, thanks!" He said in a silly happy tone.

And now…all the Mirror Knights are destroyed.

Yami sighed. "At least our friends are safe." He said.

"Dartz has no monsters to protect him." Kaiba said.

The duel continued.

And a problem occurred.

Kaiba's life points ran out!

"Kaiba! Hold on!" Yami cried.

Mokuba and Kay ran to the seal, not able to pass through. "Kaiba!" Kay cried.

"Don't screw up. I fought too hard, so you can't lose this. Now win!" Kaiba said.

"I promise I will." Yami said.

Then the seal contracted around Kaiba and soul flashed out, darting around the room and hitting one of the blank carvings on the wall, where his form appeared.

Dartz laughed. "You're the "soul" survivor!" He said.

"You disgust me." Yami growled at Dartz.

"I have what I need, so you can have the rest of him." Dartz said.

Just then Kaiba's soulless body was tossed out of the Seal, landing on the floor beside the gang.

Mokuba kneeled down to his side, weeping and begging his brother to open his eyes.

Kay kneeled down, tears in her eyes as she tried to comfort Mokuba.

"You're talking to an empty shell. Your bother has donated his life force to the Great Beast." Dartz said to Mokuba.
