Lillie and her brother are in a cave looking for an Ultra Wormhole with his Silvally and Lillie's Magearna and both of her Ninetales," We been searching for hours in this cave and found nothing"

"My phone said the Ultra Beasts is right in front of us" Silvally stop Gladion," What wrong?"

"GGGGRRRRRRRR!"

Lillie and Gladion see a very tall Ultra Beast that resembles a vaguely humanoid mass of electrical wiring. Its "head" a white, brightly glowing electric spark with numerous points and no visible face. Below its head is a mass of black cables for its torso and limbs walking toward them," Code: UB-03 Lightning, Xurkitree!" as both of their Pokemons are ready to battle, but the Ultra Beast fall on the ground which make Lillie and Gladion run toward it," This one has be defeated!"

"By who?" confuse Lillie

"By us" Lillie and Gladion look up and see a man dress in blue with a blue and black Pokemon with him. They jump and land in front of them," A Lucario!"

"I was trying to found you two, but instead I found this Ultra Beast causing trouble" inform the man

"You know about...the Ultra Beasts!?" shocked Gladion

"And you were trying to found us?" added Lillie

"Mag?"

"Yes, ever since you travel back to time, where you meant my ancestor, Sir Aaron who pass on a will to his descendants to find the blonde children with a strange Pokemons and two Ninetales in the Alola Region" explain the man

"Luc!"

"Sir Aaron, then you are..." shocked Lillie

"My name is Riley, I'm a member of the Aura Guardian with my Lucario" answered the man

"Aura Guardian!?" shocked Gladion," They still exist!?"

"Yes, we expand our order around the world" nodded Riley," Me and Lucario are from the Sinnoh Region branch and I'm the leader of that branch"

"That probably why you know about the Ultra Beasts" Gladion tap Xurkitree with a Beast Ball causing it to go in," Sir Aaron must tell you that in his will"

"He did" nodded Riley

"Why are you looking for us?" asked Lillie

"Mag?"

"During your time in the past, you help Sir Aaron with his Lucario and the past Aura Guardians to defeat a Moltres who both of you see a black shadow around it and your friends couldn't see it" answered Riley

Lillie and her brother look at each other, then back to Riley," We been wonder about that"

"How come we were the only can see it?" asked Gladion

"Because both of you are just like Sir Aaron, me and other Aura Guardians member in our order" Riley lift his right arm to summon an aura which shock the sibling," Both of you are Aura Users..."

"Aura Users!" echoed the sibling

"Aura Users are humans that can use aura just like Lucario and Riolu" explain Riley," Only a handful of humans can use aura, I will like both of you to come with me to Iron Island, where the Sinnoh Region of the Aura Guardians HQ is. So, I can help both of you to train and how to use Aura"

Lillie and Gladion look at each other and look at Riley one last time before the aura in his hand disappear.
