In a large lawn, a purple vortex appears at the front lawn, and this disappears into thin air. Out of the vortex is Ash and all of his friends appear at the new world. Luckily all of them are wearing their snow gear, just like Arceus said. They gang begin to rub their eyes after experiencing the cross dimensional travel.
Ash asks, "Do you think we made it?"
"I hope we did," Kiawe replies.
"My eyes hurt," Lillie replies.
"I guess going through a different dimension has its price," Gladion suggests.
Mallow is the first to has her vision clear up, and look to see where they all end up.
Mallow surprisingly exclaims, "Wow! Look at this!"
Everyone else are able to get their vision clear, and are surprised to see what is happening around them.
Lana kneels down, and says, "There's a lot of snow here."
"Like Arceus said," Sophocles replies.
"Hey Pikachu, don't you think it's great?" Ash asks with a smile.
"Pikachu!" Pikachu happily replies.
Gladion looks at Ash with a stern look, "Didn't Arceus wanted us to keep out pokemon hidden while we're here."
"About that, Pikachu doesn't like being in its' pokeball one bit," Ash explains.
The others are shocked by this information about Pikachu.
"Really?" Lillie asks.
"Like, not at all," Lana adds.
"Nope," Ash repeats his answers while shaking his head.
Then Ash says, "But don't worry, Pikachu can go inside my backpack so no one can see it."
"Pika pika," Pikachu says nodding its' head in reply.
Pikachu goes inside Ash's backpack, and closes it after getting inside.
Gladion decides now will be the time to start with the mission, "Okay, so we know that the Ultra Beast is in this world somewhere."
"But how are we going to find it?" Lana asks.
Ash puts his fingers on his chin, "Well, it has to be around here somewhere."
"It will be a good idea if we split up so we can find it quicker," Kiawe suggests.
Then Ash says, "And Since we were told that some people have been exposed we can ask someone about it."
"But how are we going to know who experienced magic?" Mallow asks.
Lillie turns around, and suggests, "Maybe we can start over there?"
Ash and the others look behind them to see a large building. The building is two stories tall, has multiple windows. The walls is purple with a dark burgundy my roof. And in the roof is a lot of snow.
"So what is this place?" Ash asks.
"It's kind of remind me of the Pokemon school," Sophocles says.
"So you think that place is a school?" Mallow questions.
"That what it is," A mature female voice answers.
Ash and the gang turn to see two grown women. One has light white skin, and rainbow hair of light blue, light pink, and light green, and purple eyes. The other one has indigo and dark blue striped hair, indigo blue like skin, and teal eyes. They are both wearing winter coats.
"Uh, who are you?" Ash asks.
"I'm Principal Celestia, and this my sister, Vice Principal Luna," The white skin woman introduces herself and the other woman.
Then the other woman, Vice Principal Luna asks, "And we like to know why you all on campus ground before we are open?"
Ash and the others are looking a bit concern, and wonder what they should tell them.
Principal Celestia says with a grin, "And I'm assuming that you're not from here seeing that you have a floating camera."
Ash and the others look to see Rotomdex still in public. They are are stunned to see they have forgot to put Rotomdex away. Mallow panicky grabs Rotomdex, and puts him in the bag.
Vice Principal Luna giggles, "No need to worry, judging by your appearance, my sister and I can tell that you are not of this world. And the fact you're having a floating camera confirms it."
Hearing the statement cause the gang to pause in shock.
"How do you know?" Ash asks.
"Call it a guess, and the fact we have strange magical encounters. But I don't think you possess any magic," Principal Celestia answers.
Ash and the others look at each other, and can tell these two are aware of the magical phenomenon that has happened in this world. Agreeing to the idea, the gang decides to explain the details to the two sisters.
"Principal Celestia, we have a bit of a situation," Ash explains.
"And we need your help," Lana adds.
"Your world is endanger," Lillie says in concern.
The two sisters look at each other in concern.
Principal Celestia turns to the kids, "We'll discuss this in my office. Please, follow me."
The gang nod their heads, and follow the two grown sisters to the school office to discuss the matter at hand. After getting into the office, Ash and his friends explain the two principals about the danger that has entered this world. This not only shocked the two sisters, but are a displeased that about it as well.
"So an Ultra Beast Parasite Pokemon called a Nihilego has entered this world,and you were sent here to retrieved this," Principal Celestia firmly says, getting the story.
"That's right," Gladion says, nodding his head.
"We're not making this up," Ash says.
"We need to find it before someone get possessed by it," Kiawe says.
"The last time we dealt with that creature, it possesed my mother," Lillie adds in concern.
The two sisters can see the look in their eyes, that the situation is serious.
Luna turns to her sister, "It seems that we have a serious situation on our hands."
"Yes. More than what we need to deal with," Celestia mutters.
The pokemon trainers become curious to hear what the two are saying.
"Why? Is there something else going on?" Ash asks.
"Sadly, there is. Not only that, we also have a missing student from this school," Luna answers.
"A missing student?" Sophocles shockley shouts.
Celestia sighs, "I'm afraid so. I'm afraid one of our students, Sunset Shimmer has runway."
Ash and the gang gaso that this situation.
"Runaway!" Lillie exclaims.
"What happened? Ash asks.
"To put it simple, everyone in the school believes Sunset Shimmer is responsible of exposing everyone secrets on the internet. Even her own friends thinks she did it, " Luna explains.
"And no one have seen her in four days," Celestia adds.
"Four days?!" Kiawe exclaims.
"That's terrible," Lillie adds.
"I know. Luna and I don't believe Sunset did it, but we were so busy trying to prevent a riot at the school that we couldn't find any clues to who Anon-A-Miss identity is," Celestia explains.
The pokemon trainers grow deeply concern about this, not only a wild pokemon is on the loose, by students are fighting with each other because of exposed secrets, and a girl has gone missing.
Ash is the first to speak up, "Maybe we can help?"
The two principals look at Ash, surprised to hear what he said. The others are surprised as well.
"Ash, are you we can do it?" Mallow asks in concern.
"What about the Ultra Beast," Gladion adds.
"From what I see, an innocent girl has been framed and ran away because no one believed her, not even her friends. With that pokemon on the loose, she's another person waiting to be targeted by it. If we can help the school, then they can help us find the pokemon. Besides, I feel this is the right thing to do," Ash explains.
Everyone in the room are shocked to hear Ash's speech, especially the two principals.
The trainers let out a smile.
"Count me in," Sophocles says.
"I'm in too," Kiawe says.
"We're in too," the girls reply.
Gladion sighs, "If it will help, then I'm in as well."
Ash smiles to see his friends agreeing with the idea to help.
Principal Celestia, Ash, I can't thank you enough to help us, even though you have your own problems to worry about."
"It's no problem," Ash says.
"We'll try our best to help find this pokemon, and you can help us find the identity of Anon-A-Miss and Sunset Shimmer," Luna replies.
Then Celestia says, "If you can give us a picture of the pokemon, then we can ask the students if they see it. And we'll give you a picture of Sunset."
Mallow opens the backpack, "Rotomdex can give you the picture of the pokemon, and take the picture of the missing person."
Rotomdex floats up, and firmly says, "I wish you didn't have to stuff me in a bag."
"Sorry about that, but it's alright for you to come out now and shows Principal Celestia and Vice Principal Luna the picture of the pokemon, and we need you to take a picture of someone," Mallow apologizes.
"Don't worry, I'm on it," Rotomdex says.
Rotomdex floats up to the two sisters and show them the picture, "This is the pokemon we needed to find. Have you seen it."
The two sisters take a look at the picture and are interested by it.
"No. I can't say I have," Celestia says.
"It almost looks like a human girl with a large hat on," Luna replies.
"May we have a copy of it," Celestia asks.
"Alright," Rotomdex says.
Using its abilities, Rotomdex is able to make a copy of the pokemon on the computer. Then is able to print out three copies of the pokemon. Celestia and Luna take one, and give the other two to the trainers. Principal Celestia looks through her draw and brings out a picture of the missing person. Ash and the others look to see the girl that has amber like skin, red and yellow hair, and teal eyes.
"So that's Sunset," Ash replies.
"She looks pretty," Lana replies.
"I like her hair," Lillie compliments.
Rotomdex takes the picture of Sunset, and Ash takes the hard copy.
Luna passes a sticky paper to Ash, "Here Sunset's address. Maybe you can find something that will help you find her."
"Thanks for the help," Ash says.
"I should be the one thanking you," Celestia says.
Then she, "If there anything you need, my office is always open."
Ash and his friends nod their heads, and leave the office. They all head to the main hall close to the entrance of the school. Now, the need to come up with another plan.
"So what do we do now?" Mallow asks.
"We need to find that Ultra Beast," Gladion says.
"We also need to find that missing girl," Lana replies.
Then Lillie says, "Not to mention find a way to clear her name."
"So what should we do?" Kiawe asks.
The gang try to come up with an idea to get the job done.
Ash says, "It will help if we split up, three of us will stay in the school and ask around about Sunset and the pokemon. The rest will try to find it in town."
"I think Mallow, Lillie, and I should look around at the school. We can ask around for the pokemon and the missing person," Sophocles suggests.
"I agree. Only four of are able to z moves so you can fight the beast off," Lana agrees.
"Not only that, we can go to her house and see if we can find anything that could lead to her disappearance," Kiawe adds.
Then Ash says, "It sounds good to me. We also need Rotomdex to come with us."
"Sounds good, in case the pokemon has got a hold of someone we can get a photo to identify the person," Gladion says.
Lillie opens her backpack and takes out some walkie talkies, and passes them to each friend including herself, "Take these with you. That way, we can report on what we find."
"Thanks Lillie," Sophocles says.
"These could come in handy," Kiawe replies.
"Alright, let's split up!" Ash loudly announces.
Ash, Gladion, Kiawe, and Lana leave the school while Mallow, Lillie, and Sophocles walk down the halls to talk to the students and faculty about the pokemon and the person. They hope they can find any of their answers, and hope things won't get to crazy.
