(1) \Invitation from the Demon World\ (Note: This story begins five years after the Cell Games and will not cover Buu's story from two years later.)
"Mom, hurry up!" After the Cell Games, Chi-Chi urged Goku's second son, 'Goten.'
"Coming, coming!" Chi-Chi said.
"Mom, why does it take you so long?" Gohan asked. "We haven't been to the city in so many years, of course I need to pick a nicer outfit to wear! By the way, this is Goten's first time going to the city, right?" Chi-Chi said.
"Yeah, let's go quickly!" Goten said.
"Mom, hold me tight, let's go!" Gohan said.
Then Chi-Chi grabbed Gohan, and Goten followed behind, flying towards Bulma's house. At Bulma's house…
"Why aren't Chi-Chi and the others here yet? Everyone's already here," Bulma said. Then she saw Gohan and the others flying in from the sky. "You guys are really slow! Eh, is that Goku's second son—Goten?"
"Yeah, this is Goten," Chi-Chi said.
"He looks exactly like Goku did as a kid! By the way, everyone's waiting for you, let's go quickly!" Bulma said.
Then Gohan and the others arrived at where everyone was. Gohan/Chi-Chi said, "Hello, everyone!"
Krillin said, "Chi-Chi, is that kid behind you Goku's second son—Goten?"
"Yes!" Chi-Chi replied.
At this moment, Goten, behind Gohan, stared at Trunks sitting next to Vegeta, and at the same time, Trunks was staring at Goten. Then they all took their seats.
After that, Bulma called Trunks and Goten to go play together.
"You're called Goten, right?" Trunks asked.
"Yeah, and you're Trunks?" Goten said.
"Yeah, what do you usually do at home?" Trunks asked.
"When my older brother finishes his homework, Mom tells him to teach me fighting, uh," Goten said.
"Oh! You can fight too?" Trunks said excitedly.
"Yeah, a little, I guess," Goten said.
"My dad also teaches me a bit of fighting every day and trains me, saying I should surpass your brother. By the way, come with me," Trunks said.
"Go where?" Goten asked.
"You'll see when we get there," Trunks said.Then Goten followed Trunks to the gravity room. Trunks said to Goten, 'I train here every day. This place can increase your weight, making your training twice as effective!' 'Wow, amazing! Can I try it?' Goten asked. 'Of course,' Trunks said, and then he went to start the gravity settings. 'Since it's your first time, let's go with ten times!' Then Goten felt his body suddenly get heavier. After moving a few times, he quickly got used to it and said, 'Trunks, make it heavier!' 'Alright, in that case, let's go with 100 times!' Trunks said. This time, the 100x gravity pinned Goten to the ground. Using his hands, Goten pushed himself up and then started moving his body. At that moment, Trunks said, 'Watch me!' He then ran around the gravity room effortlessly. Seeing this, Goten was unwilling to be outdone. He forced himself to adapt and was able to move freely like Trunks. 'Goten was really amazing just now. He adapted to 100x gravity in less than ten minutes, though I adapted in just five!' Trunks said. 'Hehe, you're really amazing,' Goten replied. Then Trunks challenged Goten to a fight, wanting to have a big battle with him, but Goten was hungry, and so was Trunks, so they headed over to Bulma and the others. At this time, they didn't know that someone from another world was flying toward them... Piccolo, who was with Gohan, said, 'Gohan, do you feel that?' Gohan nodded. Then Piccolo shouted, 'There!' Everyone stared at Piccolo and looked in the direction he was pointing. They saw a person with blue skin, wearing blue pants. The mysterious man then said, 'Hello everyone, my name is Storm, and I am from the Demon World.' Piccolo said, 'Demon World? You're from the Demon World?!' Storm said, 'Yes, I am from the Demon World. May I ask who is the person that defeated that Cell?' Piccolo asked, 'Why are you looking for Gohan? Do you have some kind of plot?' Storm replied, 'Just tell me, no need for unnecessary words.' 'I am the one who defeated Cell—Son Gohan,' Gohan said. Storm said, 'Honorable Son Gohan, my purpose this time is to invite you to our Demon World to participate in the "Demon World Martial Arts Tournament."' Everyone was surprised: 'What?''The Demon World's Number One Martial Arts Tournament'?” Storm said, “Yes, it's modeled after the ‘World's Number One Martial Arts Tournament' held on your planet, but the rules are a bit different. In ours, you can use weapons and even kill your opponent. By the way, it shouldn't be just an invitation for you alone; anyone with high martial arts skills from your world can participate.” Gohan said, “I accept your invitation, but when will it be?” Storm said, “It will be three days from now. I will come to pick you up. Now, I'm leaving!” Then a gust of blue wind blew, and Storm's aura disappeared from Gohan and the others' world.
