(A/N) Welp, it's decided😂 Aureliashipping wins, I'll find a way to insert Lillie, and before I forget, I'm gonna insert Aria also since you guys agreed on putting her up in this story.

And, I'm really sorry guys for the long wait, the school is keeping me occupied, more and more assignments to be answered, I'm even having a hard time writing chapters, and mostly, publishing up chapters, add up the phone's stupid lags. I can hardly find time making chapters, I'm really sorry...😖

So anyways, here is a chapter, I think this will just a filler chapter for...something?😂

Serena's POV

In a particular classroom where all of the students are now learning Pokemon Battles, one student wasn't really calm and kept herself being-

"Who was it?!" I yelled suddenly in the middle of the class, all of their eyes were now on me, I hid myself under the desk, and apologized for the sudden scream.

"Next time, don't do that." Professor Birch scolded me, then he went back to the lesson.

"Serena, that will be your 50th time repeating those words, what's wrong with it by the way?" Dawn said, I can't believe she counted it.

"I swear there's someone who saved me before you guys came!" I retorted, I can't move on at the fact that someone saved me, I owe him or her my life!

"The one who sent the Pidgey, maybe it's also connected." I continued on, Dawn and May kept on listening to what I was saying.

"Maybe there's someone- Oh wait! I cant believe you guys forget him!" Dawn quickly recalled something, ears where now on her.

"Who?" I asked her, ears were now perked on her, we are waiting for her answer.

"Don't you dare forget the mysterious boy!" Dawn acknowledged, that rang the bells on our minds, how can we forget the mysterious boy?!

"How can I forget?!" I scoffed, Dawn and May sweat-dropped at this. "Maybe he was the one who saved me! He was the one who sent the Pidgey with the letter!"

"Now that you've said it, we know a place where we can track down the mysterious boy." May said, that's maybe a little true, but I don't really think the mysterious boy is staying there, it's a forest after all.

"Maybe it's a coincidence May." Dawn defended, she does have a point. Maybe it was a coincidence that I am there and the boy was also there.

"Anyways, did you see another Pokemon of his?" Dawn leaned on me with sparkly eyes, May sweat-dropped while I nervously laughed.

"Now that you asked it, I heard him command something like Thunderbolt and Aura Sphere." I reminded her, then that's when I realized.

"So it's possible that..." May started.

"An Aura Sphere can be learned by a..." Dawn continued on.

"A Lucario!" I finished what they are about to say. Lucarios can learn Aura Sphere! Then that's it! The mysterious boy also has a Lucario! Now that's a great discovery!

"So that boy has a Lucario..." Dawn said.

"What a rare Pokemon...you know, Lucarios and Riolus are hard to find." May stated.

"And the coincidence you're talking about a while ago Dawn...what do you mean by it?" May continued on.

"What I mean by coincidence is, what if the boy was just there the exact time Serena was being caught, and you can't just say that you can already track that mysterious boy, that's is if he's the one who saved Serena." Dawn explained.

"I'm pretty sure he's the one who saved me." I retorted back.

"How can you be so sure about that?" May's brows twitched.

"Remember what I said about Thunderbolt and Aura Sph-" I was cut off by the sudden realization of Dawn.

"Oh! I get it! It was his Pikachu who used Thunderbolt!"

"Maybe that's the place where he was staying!" I squealed.

"Probably."

Ash's POV

"Ugh! I hate this!" I yelled to no one. Pikachu and Lucario's head tilt in confusion.

"What is it master?" Lucario asked, Pikachu also nodded at this.

"Now they found out where we are staying." I frowned, I really don't like them finding out my hiding spot.

"Are you not happy about that." Lucario and Pikachu chuckled.

"Of course not...trust me, they'll come back sooner or later." I glared at the two, making them sweat-drop.

"Planning on switching places master?" Lucario and Pikachu grinned, they looked like their excited at this.

"I want to move, but, I'm gonna miss this place." I acknowledged them, making them frown at it. They also lived here since we were little. Pikachu was my first partner, It is where I also found Lucario, here in this very forest.

~Flashback~

I was walking at this forest, with an injured Pikachu on my arms, we just got into a battle a while ago, but the opponent gained dominance, and it defeated me, I regretted being Pikachu's trainer...

"Pikachu, I'm sorry for being the worst trainer you've got..." I apologized at Pikachu, Pikachu got irritated, and slapped in on the face.

Pikachu murmured something, of course I didn't understood it, but I'm trying to get what Pikachu was saying.

But that question was answered by Pikachu licking me on the face. Tears were now dropping from my eyes. Pikachu gave me a smile, making me smile back.

"I promise I'll be a good trainer for you." I said to Pikachu, Pikachu nodded, and jumped on my shoulder.

Then a sudden sound, or shall we say, a cry, was heard from afar, were trying to track where that sound came from, as soon as the cry gets clearer and clearer, we started to run and find the source of cry.

And after that, me and Pikachu arrived at a small clearing, then we saw a small basket, making us tilt our heads in question, we approached the basket alertly, but as soon as we saw what is inside the basket, me and Pikachu gasped in shock. A baby Riolu was in the basket, peacefully sleeping. I leaned beside the basket, carefully not waking up Riolu, but unluckily, it woke up, and stared at me curiously. But what really surprised me is...

"Are you my father?" Riolu just suddenly said, making us got shocked further and further, we're really surprised that...it can talk!

"Y-You can talk..." I hardly said, I really can't believe I can find a baby Riolu that can already talk!

"O-Of course I can talk! You're really rude!" Riolu pouted.

"N-No! Not that! It's just that...Usual Riolus can't talk..." I sweat-dropped, Riolu curiously stared at me.

"...this is the first time I discover a Riolu talking, a baby Riolu." I continued on, Riolu just kept on staring at me.

"I-Is that so?" A hint of curiosity can be heard from the question of Riolu. It's voice really sounds like Telepathy.

"Of course!""Pika!" Me and Pikachu nodded sheepishly, I think Riolu is processing something until...

"Let me come with you!" Riolu suddenly squealed, making me and Pikachu shocked at that. And I don't know what to say.

"Since you're the one who found me, I think you'll be a responsible trainer for me!"

~End of Flashback~

And that's that, since that day, me, Pikachu and Lucario we're good friends, we kept battling trainers from around the place, I'm really surprised about Riolus skills that time.

That's why it's too hard for me to just leave this place, this place has many good memories. I can't just let them go easily...

???'s POV

"Are you gonna switch school Lillie" Lana asked, wearing that really cute puppy eyes, I really can't handle Lana's puppy eyes, it's too cute, oh and her sisters too!

"Yep, but don't worry, I'll visit occasionally!" I told them, I will just go home here if I am in the mood, but I'll always come here because I'm always in the mood, maybe?

"We're gonna miss you Lillie!" The greenhead girl, or Mallow, yelled, even if she was just a really short distance apart on me.

"And I'm gonna miss you too Mallow." I replied her back, oh how I'm gonna miss this greenhead stubborn girl, I patted her head.

Before I forget, the name is Lillie Aether, a top student here in Pokemon School, but my mother wants me to switch school with the Kalos High, she said that the reason is that she has something to do there, she just mentioned that it'll take long.

You can probably ask, 'Lillie, how did you become a top student in Pokemon School?', well, before I'll answer that question, Pokemon School is not the school you've been thinking, it isn't a school for Pokemon battles, it is more like an ordinary school, school for studying, and tests, since I know everything about Pokemon, except Legendaries, I only know a little about them, that made me a top student here in this school.

And you might probably ask, 'Lillie, why you just know a little about Legendary Pokemons?', no one has ever found a legendary Pokemon, even the Professors here in Pokemon School doesn't encountered a single Legendary Pokemon.

Legendary Pokemons are really hard to track down, even the newest and the best technologies of tracking one of them cannot do a thing. But here's the thing, we might know a little about them but we surely do know what's their forms. One is what they call 'Mew', they say that this Pokemon is a really rare Pokemon, it is a pink feline small floating Pokemon with a long tail, some of them considered this Pokemon a 'mythical pokemon'. I'm really looking forward to seeing one.

But enough of that, me, my brother, Gladion, my mother, Lusamine and Butler Hobbes are now ready for the flight to Kalos. Gladion always wear that bored expression, since he was also considered as the 'toughest and strongest battler' here in Alola, kind of exaggerating but true. His pokemon, or what he was always calling it, 'Type:Null', always crushes whoever it's enemy is. Type:Null is also considered as a rare Pokemon, and others say that Type:Null is a clone of Arceus, the Alpha Pokemon, I do know a really little information about Arceus, only that she is the one who created Pokemon.

"Hey Lillie! You're dozing off." Gladion waved his hand in front of me, making my imagination cut off.

"Oh? Oh, I'm sorry, I was just occupied by something." I gave Gladion an apologetic smile

"Something?" Gladion looked at me.

"Like, what we'll gonna do once we get there!" I quickly answered.

"Oh I know what I'm gonna do, I'll challenge the strongest trainer there in Kalos High!" Gladion smirked. One of the most hated personalities of him is this attitude of being proud, it's like it was raised to the highest level.

And I've been thinking, maybe there's also a strongest battler at Kalos, if I ever find one, I'm gonna let him or her challenge my brother. He has 100 winning streak, and I wanted to break that streak with the help of that someone, I don't know why but it will give me happiness inside.

"Lillie, Gladion, once we get there, I need to go to my destination as soon as possible, so can you two take care of your own and go to that school by yourselves?" My mother asked, I don't know why, but she's always busy with her work, even me and brother always noticed that.

"Sure Mom, just be careful." I said to mother, Gladion stared curiously, but just nodded and decided to take a nap.

Since it'll be a long flight, maybe I should take a nap too...

Ash's POV

"Lucario, let's just stay here." I decided. Lucario and Pikachu looked at me, at times like this, I should support my decisions.

"Since this is a place with great memories, I shouldn't abandon it just because I was found out." I gave them a reassuring smile. Lucario and Pikachu then agreed.

"They're probably gonna be back soon." I sweat-dropped."Maybe we should take a nap first.

"Gladly master."

Serena's POV

"School is over!" May suddenly jumped and yelled in excitement.

"What happened to you May?" Dawn and me chuckled. May's not like this, I wonder what's wrong.

"Serena, Dawn, since we still have a lot of time left, why don't we go to that place again?" May invited us, I think that's a really good idea, but I don't want to happen again what happened earlier.

"Don't worry! Let's bring the others!" May continued on. I think they will agree on it, but let's just see.

We then agreed on May's plan and then went off finding the others. First stop is Misty, she agreed on this, then Gary and Paul, they also agreed at this, then lastly, Brock, who also agreed, then together, we went on the same forest as before.

...

"Finally! We arrived" Misty yelled, stretching her tired arms.

"Quiet down will you?! He will find out!" Dawn whisper yelled, Misty realized, then quickly covered her mouth.

"Why did we agreed on bringing Misty..." Gary sighed.

"What did you said?" Misty fumed, Gary nervously laughed while me and the others sweat-dropped.

Minutes later, they are now calmed down, and we continued on walking quietly through the forest, we were amazed at the scenic view of the forest, I wonder if the mysterious boy really lived here.

The forest was really really quiet and peaceful, the chirps of the Pidgeys are quite soothing, we tried our best not to make noise, maybe the boy is nearby, and we don't want to surprise him. And I think-

'Crack!'

A twig was snapped, and I think someone stomped it, that was a loud crack there! We stopped and then looked at Gary, who stepped on a large twig and was broke into two.

"Oops? Sorry." Gary sweat-dropped.

"We're doomed."
