In Shin's imagination, the "practice" ground for Tohru and Kanna should have been the unpopulated grassland from the original work.
In the original work, Tohru and Kanna had "playful" sparring sessions on that grassland and nearly set the entire prairie on fire—the commotion was quite spectacular.
However, soon after Tohru landed, Shin realized he'd guessed wrong—the place they landed wasn't a grassland but a deserted island in the ocean.
"A deserted island... Indeed, this kind of isolated small island in the ocean not only has no human presence but is also less likely to be detected as abnormal by satellites."
Shin jumped down from Tohru's dragon back and surveyed the deserted island's environment—the island was completely flat with no undulations, and showed no traces of vegetation or animals.
"But I didn't expect there'd still be such a desolate island, with hardly any plants... How did you find this kind of deserted island?"
"Ah, this island actually had some plants and animals, but they all disappeared during Kanna's and my training."
Transforming back to human form from her dragon state, Tohru heard Shin's words and waved her hand with a smile, casually saying something that would sound quite exaggerated to ordinary people.
"And this island originally had a mountain and wasn't this flat—it just got leveled a few days ago by accident."
Well, thinking about it, Tohru and Kanna's "training" was a battle between two giant dragons. How could they not leave any traces on this island?
Although Tohru and Kanna's strength didn't amount to much in front of Shin, Tohru had said in the original work that destroying a country wasn't difficult for her.
Rather, the fact that the island's mountain peak was only leveled a few days ago already meant it had persisted for quite a while—Shin had thought the mountain should have been flattened on the first day.
"So, Akawa, what do you need this uninhabited place for?"
Tohru's face showed a trace of excited smile as she moved closer to Shin and asked him curiously.
"Could it be you want to do that kind of thing here? Tohru doesn't mind at all."
Whether it was because they'd played too wildly in outer space last time, Shin felt Tohru seemed to have unlocked some incredible personality trait and was becoming increasingly bold.
Although this place was indeed certified by Tohru and Kanna as somewhere no one could discover, Shin didn't come here to release his desires with Tohru this time.
"Stop fooling around, I have serious business to test. I just wanted to find an uninhabited place."
Shin glanced at Tohru and said helplessly, then once again took out the "repaired" Planet Cyril Dragon Balls.
Seeing Shin take out two seemingly unremarkable orbs and place them on the ground, Tohru crouched down to observe carefully, then asked puzzled:
"What are these? Some kind of rare gemstone? Since when is Akawa interested in this kind of thing?"
Although Tohru didn't usually show it, as a dragon, she actually had quite standard stereotypes—such as a fondness for treasure.
She had a somewhat familiar dragon in the other world named Fafnir, whose desire for treasure was even more exaggerated than ordinary dragons—becoming extremely fierce whenever treasure was involved.
Tohru had even already decided in her heart that if Shin was really interested in jewelry, she'd make a trip back to that world and steal Fafnir's treasure for Shin.
Naturally, Shin didn't know Tohru had already planned to rob an acquaintance for his sake. Seeing her curiosity, he explained:
"This thing is called a Dragon Ball. It can summon Shenron and can be used to grant wishes."
"What!? Shenron!?"
Tohru's eyes widened with an incredulous expression, even her voice rising an octave.
Seeing Tohru's reaction, Shin was rather curious instead—he hadn't expected Tohru to react so strongly after hearing about Shenron.
Could it be that Tohru's world also had legends about Shenron or something?
However, immediately after, Tohru's statement left Shin completely speechless.
"Akawa, you have another dragon on the side!? Is there something I'm not doing well enough!?"
Tohru threw herself at him entirely, her tone sounding like she was about to cry at any moment, constantly rubbing against Shin and making plaintive cries.
It seemed she didn't know what Shenron was and simply thought Shin had another dragon on the side.
New girls had always been joining the household before, and Tohru had endured it because she felt her position as a "dragon" was irreplaceable—the other girls weren't in the same league as her.
But now hearing Shin mention some "Shenron," Tohru felt a sense of crisis, which was why she was acting so flustered.
"Alright, this dragon isn't a girl, and it's not the same as you. Just think of it as a tool for granting wishes."
Shin irritably pushed Tohru off himself. After finally getting her to calm down, he sighed and prepared to begin summoning Shenron.
The incantation was the same as before, since it was still Planet Cyril's Shenron.
"Takara puto, Tete ron po, Pupiritto paro."
As Shin recited Planet Cyril Shenron's summoning incantation, the two Dragon Balls on the ground clearly showed some reaction.
The surface of the two Dragon Balls slowly began to glow, like lightbulbs being turned on—but then, nothing more happened.
Shenron didn't manifest as it had in the Dragon Ball world. The two Dragon Balls shook slightly, then quieted down.
"Eh? Did it fail?"
Tohru watched from the side as the Dragon Balls showed movement but then settled down, and couldn't help asking Shin curiously.
"It looks like it failed."
Shin narrowed his eyes, looking at the two Dragon Balls on the ground—now that he possessed knowledge related to Dragon Balls, he was very clear that summoning Shenron had indeed failed.
Probably because of the difference in worlds, these Dragon Balls were created with the authority to interfere with the Dragon Ball world, but this authority couldn't be used in other worlds.
"However... it hasn't completely failed."
Shin extended his hand again—the next moment, two Dragon Balls very similar to the Planet Cyril Dragon Balls on the ground fell from the "Gate of Babylon."
There were still two Dragon Balls, but compared to the genuine Dragon Balls on the ground... these two Dragon Balls' glow was much dimmer, looking like lightbulbs with insufficient power.
That's right, these two Dragon Balls were counterfeit Dragon Balls, created by Shin in the courtyard using "Projection" magecraft.
They were Shin's own Dragon Balls.
