Kukui's House (Night)
A loud explosion woke up the shirtless Professor, who was sleeping at his desk. "What was that?" he wondered, looking around his lab. Nothing was out of place, so it must've come from upstairs. Passing by the Luvdisc tank, he walked upstairs to see that there was nothing visibly wrong with his home. Rockruff was sleeping on the couch, but that was expected of the Puppy Pokemon. "Did it come from outside?" he said, walking to the front door. It wouldn't have been the first time a battle broke out on the beach in front of his house. As soon as Kukui opened the front door, he could see a large plume of smoke coming from the beach. Worried that a wild Pokemon might be injured, he ran down to the beach. What he found was nowhere near what he expected.
Laying in the sand was a 10-year old blonde boy. He wore a plain white shirt and a red hoodie, though both were covered in burns. He also wore jeans that were burned away from just below the heel. Next to the boy was a Mimikyu, also unconscious. Because Mimikyu were virtually nonexistent on Melemele, Kukui could tell that it was this boy's Pokemon.
'What happened to these two?' the Professor asked himself, picking up the boy and his partner. They both needed immediate medical attention, and the Pokemon Center was too far away. With little hesitation, he brought the child into his home along with his Pokemon. He could perform basic medical procedures, but as soon as that was done, he'd allow the Pokemon Center to take them in. As he set the boy down on the couch, he noticed that he was wearing a Z-Ring with a Mimikium Z inside.
Was the kid a Trial-Goer from Ula'ula? Then why was he all the way here on Melemele?
With a gasp, the boy awoke and shot up. "Where am I?" he asked, looking around until his eyes landed on Kukui. "Professor Kukui?"
"Do I know you?" the man asked, confused. He was well-known in Alola, but for a random kid to address him like this? He may not have been the best at reading people's tones, but it sounded like the kid knew him personally, or at least, thought he did.
"What?" the boy said, astonished. "Wait, does the name 'Necrozma' mean anything to you?"
"No. Should it?" Kukui asked.
"No. Sorry. I thought you were someone else." the boy said, saddened.
'But, he used my name.' the Professor thought to himself. "It's fine. Do you remember how you and your Mimikyu got hurt?"
Hearing the name of his partner, the boy picked up the small Pokemon. "We were exploring. While we were traveling through a forest, a flash of light blinded us. Next thing I know, I woke up here." He turned his gaze to the loft above. "Do you mind if I spend the night here?"
"Not at all." Kukui said with a warm smile. "By the way, you never told me your name.
"Oh, it's Dominic." the boy said. "Dominic Xiao-Long."
Kukui's House (Night)
Dominic didn't sleep that night. How could he? Hearing a rustling noise, he turned to his partner, who was finally awake. "Hey, glad to see you're up." he said, allowing the small Pokemon to jump into his arms. "At least you're here."
Sensing its trainer's distress, Mimikyu nuzzled closer to him.
"Thanks, but the issue is a bit bigger than what you can fix." Dominic said. "We're lost. I don't know how, but we were swept into a parallel world. At least the first person I met here allowed me to stay in his house for the night, but once morning comes, I have no idea what to do." Gazing through the skylight and looking up at the night sky, he made a vow. "No matter what happens in this world, I will do as I always have and protect the balance of nature."
AN: Sorry for the short prologue, but there was nothing else I could cram in here. Happy Halloween, and I hope you enjoy this new story.
The next chapter will hopefully be a bit longer, but until then, please tell me what you think of this one.
