As the final showdown begins, Tezha dashed against Voldigold. Tezha used his spirit fist on a small scale, while his mecha manifested it on a larger scale. Voldigold, the demon, gasped for air as Tezha's mecha delivered an uppercut that sent him flying upward. He landed on hard concrete, breaking it, and then sank into an underwater section. Tezha followed up by dashing toward him. As Voldigold prepared a punch, the controlled demon stopped it by catching his hands. When Tezha's mecha threw another hand, Voldigold caught it and then kicked the mecha in the sack. The mecha began to jump up and down, clutching its "sack," and the controlled demon caught it mid-jump, tilting it to deliver a resounding F-5 impact that broke the arena.
Tezha in his mecha was dazed. The controlled demon then jumped onto the mecha and continued to rain blow after blow. It seemed that Tezha was giving up; inside the mecha, he was injured—apparently, any damage to the mecha also affected its controller. Tezha's face became covered with blood as he saw a vision of himself and Nezha. Nezha spoke to him, "You're my disciple. I like you; you always behave like me. But there is something I can't do: I can't pass out mid-battle—I'd rather faint after the battle. And secondly, you are not using your full powers. Since you are my disciple, you're supposed to have a mark on your forehead. I want you to channel that power into yourself. Allow it to flow through you; become one with it. Don't try to control it—let it control you."
"Bye; go win your battle in the arena," Nezha said. The controlled demon cheered and trash-talked, "There is no one who can defeat me!"
The scene then shifted to the Demon King and Leo. The Demon King asked, "Do you think the fight is over?"Leo replied, "No, the fight is just getting interesting."
Back in the arena, the controlled demon raised the mecha and displayed it as a trophy. Suddenly, power began to emit from the mecha. The mech became fully engulfed in fire and started to melt down. Tezha was seen in a lotus stance as the mecha melted down; the lava was great—but Nezha controlled it and began to compress it, spinning it to form something like a pill. Tezha swallowed the pill. Slowly, he opened his eyes; they were completely blank, and then began to emit fire. In an instant, the controlled demon was sliced clean by a spear.
Tezha stretched out his hand, and the spear came to him while undergoing a transformation. It became a full flame spear, with only the middle section remaining unconsumed to serve as a handle. Tezha then used his hands as if they passed through a portal. The portal opened behind Voldigold, and Tezha's hands caught him, dragging him toward the portal. As the demon came face to face with Tezha, the next thing seen was his head rolling clean on the floor. Voldigold, dazed, only saw his body kneeling without a head. "This is how I will die—but my master, I still haven't done enough for him. No, I will not!" he thought as he saw an image of the Demon King giving him a thumbs-up. "This isn't how I will die," Voldigold declared, and his body obeyed his command to merge back with his head.
Standing up, he brought out a weapon resembling a katana. "This is my ultimate weapon: the Katana of Devastation," he announced. He swung it with such force that he completely shattered the surrounding climate. The shockwave from the katana made the dimensional barrier visible. Tezha then said, "Let's wrap this up, shall we?" as they both charged their strongest attack.
Tezha levitated, adopting a dragon stance while his spear rotated at a speed beyond typical human calculation. As the rotating speed slowly overcame the devastational slice, he channeled his power into his spinning spear. The spear then materialized into a fiery giant hammer. When the giant hammer was swung, it collided with the enemy's attack, completely accelerating the dragon inferno spear attack. Inch by inch, as it inched closer to Voldigold, the demon stood there, closed his eyes, and finally thought, "I did it. I have served the Demon King, and I'm honored to stand by his side—even though I didn't expect to die fighting him. He is an opponent who makes me feel alive. If I am to be reincarnated, I would love to stand by your side."
Accepting death, Tezha ceased his attack. "You have already admitted defeat. I am a god's disciple, so I won't kill you—I've already done it once. I won't do it again; consider it my mercy." He stretched out his hand to Voldigold, who accepted it. As the dimensional portal opened, Tezha was seen assisting Voldigold, carrying him out of the arena and into the Demon King's castle.
Later, Leo declared, "It has been decided—we won. I would love it if you left my planet alone."The Demon King retorted, "We are at war, not in a competition, so I won't leave your planet alone."Leo replied, "Fine by me then," and instantly teleported to the Demon King, saying, "In order to stop this war, I simply need to kill the general; then the remaining forces will run for their lives. With the general gone, the rest will be scattered, and they will all fall to my blades and my armies will rejoice in valor."
"Right, Demon King—or should I say Vonheart? Hmm, Leonard, you knew my name. That means you should know that I am not the leader of this army; I am just a pawn at the hands of my master. We serve the God of Darkness, Denzan. With the wave of darkness that has passed, it is a sign that he has awakened and that he will soon come to set us free."
The scene shifted to Denzan in Tartarus. He thought, "My lackeys are getting their asses handed to them; I need to do something." First, he calmed the flames in Tartarus, then used his black holes to absorb them, saying, "This is my creation—I'm just taking it back." He converted the absorbed flames to dark mana. After a little time, he absorbed all the flames in Tartarus and decided to trace where the mana was coming from. "I think the flow stopped at the edge of the universe. I know those gods already have a defense mechanism, so I need to go there."
Since it had been long since he saw Vultra, Denzan, as the Void, walked to the edge of the universe. Though it seemed boundless, he knew it was just a reflection meant to break the hearts of anyone who came there. "Well, time to announce my presence," he said as he increased his aura; the reflection shattered. Out from the debris came a beast bearing a mark that read "Nullifier" in the gods' language. The beast, detailed like a lion with wings and fur emitting darkness and flames, possessed an air of intelligence. It was called the Gatekeeper. Its tail consisted of seventy conjoined snake-like formations with a king cobra in the center, and its paws emitted flames, casually forming a path wherever it walked.
The beast said to Denzan, "Who dares to disturb me?"Denzan glared and replied, "You have something that belongs to me. Now give it back, damned beast!"The beast retorted, "Oh, that's some nerve coming from a lowly human.""Anything about me being human?" Denzan demanded, showing his god form—a being transcending all bounds, with massive black-hole eyes and a body composed of countless black holes. His aura turned every place dark; not even the brightest star could stand a chance near his absolute darkness."Emmm, beast, now come forward and entertain me," Denzan commanded.The beast, knowing it was not a match but unwilling to back down, replied, "I was created for the purpose of protecting this dimension. I will not simply give in to some god who came out of nowhere."Denzan said, "Oh, you murmuring fool—I don't like those who murmur. Are you going to entertain me, or should I destroy you for my entertainment?"When the beast did not reply, Denzan roared, "Okay, time to entertain me," unleashing ten supermassive black holes that started absorbing all matter around him. The beast, slowly beginning to be absorbed, cried out, "Please, have mercy—don't do it! I have a treasure I can give you!"Denzan snapped, "It's too late to say sorry," increasing the size of his black holes. The beast screamed as it was completely absorbed. Denzan then cooled down, no longer needing his ascended god form, and entered the dimension he wished to use. His void step was entirely canceled out, for he was in Vultra's domain, so all abilities were nullified.
Vultra sensed a presence similar to Denzan's. He sent one of his many lackeys, instructing him to bring the person to him. The lackey left, and the intruder immediately appeared before Denzan. Denzan was knocked out by a single punch. When he opened his eyes, he found himself in a dark castle. A wild Vultra stood before him and demanded, "Who are you? What are you doing in my domain?"
The scene then shifted to Leo and the Demon King, who prepared for a face-off as the entire area transformed into a separate, unrestricted world. Leo said, "Now, let the generals fight it out."
