The World Martial Arts Tournament ended, and naturally, Setsuna won the championship.
However, Satan was not at all discouraged. Instead, he followed Setsuna with great excitement.
Because Setsuna said he could teach him martial arts.
"Mr. Setsuna! No... Setsuna-sensei!" Satan rubbed his hands, his eyes shining. "I want to become as strong as you too. Well, even one-tenth as strong would be fine!"
Setsuna couldn't help but look at him strangely. After all, at his current level, one-tenth of his strength could easily thrash a God of Destruction.
"Hmm, the first thing you need to master is Ki."
"How can I master this magical 'Ki' of yours?" Satan's eyes were full of longing.
"Your body has actually long since surpassed the threshold for comprehending 'Ki'. It's just that you lack the awareness, which is why you've never gotten started."
As Setsuna spoke, he found it amusing.
After all, in the original work, Satan had taken a hit from Cell and only suffered minor injuries.
Meanwhile, Krillin from the same era had been beaten to near death by a single blow from Cell.
Soon, under Setsuna's insightful guidance, Satan's mastery of Ki was almost effortless.
Satan even mastered the flying technique.
"Wahaha, I can fly too!" Satan 'breaststroked' through the air, immensely excited.
Then he saw Krillin and the others flying over.
Among them was the boy who was often with his daughter.
His old face reddened. Seeing the anxious expressions of Krillin and the others, he asked, "Are you looking for Setsuna-sensei?"
"Setsuuna... sensei?" Krillin and the others looked at him strangely, never expecting Setsuna to take Satan as a disciple.
Gohan's expression was even more subtle, 'If Mr. Satan became Uncle Setsuna's disciple, wouldn't that mean I could call Mr. Satan my 'junior disciple'?'
Fortunately, their attention quickly shifted away from Satan.
Krillin landed from the air and said urgently, "Setsuna, big trouble! Two super terrifying demons have appeared on Earth."
"One is a pink fatso, the other is a blue goat old man. They're fighting in the western desert. Either one of them could destroy Earth!"
Satan listened nearby, completely bewildered, 'Earth was about to be destroyed again?'
Shin also stepped forward, his tone grave. "Setsuna-sama, the situation is even more serious than you think. Moro is an ancient planet-eater, and Buu is an ancient apocalyptic demon."
"No matter who wins or loses, it will be a catastrophe for Earth and even the universe! I implore you to come with us, to combine our strength and find a way to stop them!"
Hearing this, Setsuna showed no surprise. He nodded calmly.
"I've already sensed their Ki. They are indeed strong. But defeating them isn't difficult."
"Not difficult?" Krillin and the others were stunned. They knew Setsuna was strong, but these were monsters that even two Super Saiyan 3 warriors couldn't handle.
With that, Setsuna looked at Satan. "Satan, you come with us too."
Satan was thrilled. "I can also participate in the battle to save Earth?"
He was just fantasizing about becoming Earth's savior when suddenly the space before him shifted.
When his vision cleared again, they were above the western desert, where the sky was filled with yellow sand and energy ran rampant.
Below were the ruins of Buu's spaceship, and in the sky, two terrifying figures were locked in fierce combat. Dark purple and pink energy constantly collided and exploded, shaking space itself.
"Th-this is teleportation? Amazing! It's a miracle!" Satan shouted and exclaimed.
But at that moment, no one had the heart to pay attention to Satan's amazement.
Everyone's eyes were drawn to the battle in the sky.
The fight between Moro and Buu seemed to have just concluded. Most of Moro's body had been swallowed by Buu.
"What?" Krillin exclaimed in shock. "That pink fatso is that strong? Moro was a monster that even Goku and Vegeta together couldn't beat. He's just been eaten?"
However, Shin's gaze was extremely grave. "No, Moro deliberately let Buu eat him!"
"What?" Krillin looked over in confusion.
Shin explained urgently, "Moro must have noticed that although Buu is powerful, his mind is not mature."
"He willingly let Buu eat him, intending to fuse with Buu from the inside."
"This way, he can not only gain Buu's immense power and special constitution but also compensate for the flaws of his own aged body."
As if to confirm Shin's words, Buu, who had been patting his belly in the sky, suddenly froze.
A look of extreme pain appeared on his pink face. He clutched his round belly with both hands, and his body began to roll uncontrollably.
Soon, Buu's body began to change.
His skin tone started to shift toward dark purple. The nubs on his head differentiated into two curved horns.
Within a few seconds, Buu transformed into a dark pink-purple 'pink goat demon', a mixture of Buu's simple silliness and Moro's ferocity.
"Hehehe, success!" The merged monster spoke in Moro's voice.
"They actually fused!" Krillin's voice trembled. "Setsuna, can you still handle this now?"
Setsuna said calmly, "Don't worry. It's not a big problem."
Hearing Setsuna's voice, the merged Moro spun around, his gaze fixed on Setsuna. "Chiaki Setsuna, you really are on this planet!"
"Seven years ago, it was you who resealed me just as I was about to break free. I have never forgotten that 'favor' for a single moment!"
"What?" Krillin and the others were very surprised. This demon actually knew Setsuna, and had even been sealed by him.
"Seven years ago..." They suddenly recalled that during the Cell Game seven years ago, they had asked the North Kai to contact Setsuna.
But the North Kai had told them that Setsuna was fighting a far more terrifying enemy than Cell deep in space.
So that enemy was the Moro before them?
Vegeta clenched his fist tightly, 'Setsuna had sealed an enemy seven years ago that I couldn't even defeat now. Was the gap between us really that vast?'
Facing Moro's hate-filled gaze, Setsuna's voice was calm. "You dare come looking for me? This time, the outcome for you won't be a simple sealing."
"Hmph, bluffing. I can see right through you!" The merged Moro was dismissive. "Now you are no longer the incorporeal, elusive soul state you were back then. You have a true physical body."
"Having a physical body means you have energy and life force for me to absorb."
The merged Moro spread his arms and laughed arrogantly. "Next, right before your eyes, I will devour your friends and your hometown completely. I'll show you what a true nightmare is!"
