Hikari and Siren's Adventure

Chapter 1: Hikari and Siren

.

"What a great weather, Piplup!" commented blue haired coordinator. Hikari continued her journey in Hoenn region to aim to be a Top Coordinator. Currently, they were in Petalburgh Woods on their way to Petalburgh city.

(Meanwhile, somewhere else)

"Those meddling PreCures!" a black cat remarked in anger as it dashed away from people. She panted after running as fast as she could. "Grr! I wonder how I'll defeat those girls!?" suddenly she heard a giggle. "Who's that?" she asked around but no responses. She settled down as she thought, 'is it my imagina-'

Then a ring appeared before her, sucking her in. When she opened her eyes, she found herself in a weird dimension. No gravity, no people, as if that world never meant to be no one. It was only her… in that empty place.

After scanning her surroundings, she jumped to another hole. Thinking it was her way in before, so it has to be the portal back to the place she were. Unfortunately, she was wrong. The hole she jumped in wasn't the hole that she entered to the empty world. Unbeknownst to her, it led her to another world.

...

"Did you know, Piplup? The episode of Suite PreCure on TV yesterday…" the blue haired coordinator started to enthuse her favorite TV shows to her Penguin partner. On other hand, Piplup yawned and demanded Hikari not to tell him again and again. Hikari apologized, "Hehehe… sorry. I've told you the latest episode for thousand times, huh?" as she placed her right hand on the back of her head. Piplup yawned and attempted to say something to its trainer. "Don't tell me, you want to sleep in Pokeball?" she guessed. Piplup responded by a nod.

Hikari returned Piplup to its Pokeball. She glanced another pokeballs she held on her hand. "Okay, then I'll- Gah!" an unknown creature landed on Hikari's head. It was heavy, causing Hikari and pokeballs on her hand to fall on the ground. "What was- ah! This black pokemon… this is the first time I see it." Hikari knelt and studied the black cat. She spotted some scratches on its body which Hikari sprayed some potions on its injuries.

"It hurt!" groaned the black cat or known as Siren. Hikari drew back as the cat talked. Hikari had a hunch about ability of this cat called telepathy. On Hikari's memories, she didn't recognize this kind of pokemon at all. Even pokedex couldn't tell.

'Is it… a newly discovered pokemon by any chance? Maybe it knows what pokemon it is. After all, it can telepathy.' Hikari wondered. "Ah! I haven't introduce myself yet. I'm Hikari. You are?"

Siren meowed in order not to let her identity discovered. It kept replying some meows no matter what kind of questions Hikari brings.

"What are you talking about? I don't understand. Ah… or your ability isn't telepathy? Then what it is?" Hikari folded her hands as she tried to think.

'What's with this girl?! In any case, it feels like I'm neither in Minor Land or Kanon town. Where am I exactly?' In the middle of Siren's thought, Siren spotted a Politoed and several Poliwag walking in group behind Hikari. Siren finally realized where she was – in Pokemon world. She recalled some animation on TV which was quite famous among kids in Kanon town (even several kids singing pokemon theme songs) called Pokemon. 'If that makes sense… then where are the portal?' She caught a sight of the same ring above Hikari that sucked her in back in Kanon town. However, it was to tall to reach. So, Sire changed her appearance to make herself fit in the ring.

Much to Hikari surprise, the black cat turned into herself?!

"Thank you for letting me borrow this appearance!" was Siren's first sentence to Hikari for real.

Hikari gasped in panic, "You… what pokemon are you?! Why you can—no, no, no. That's not it. Um…umm."

"With this appearance, I shall go to another world and defeat those PreCure. Bye!" with that, Siren jumped to the ring or hole to back to Kanon town.

"Another world? PreCure? Is that pokemon addicted by some TV animations?" Hikari bewildered. "In any way, I won't let you do something with that look!" Hikari jumped to the ring of hole Siren entered.

Hikari found herself in a very dark dimension. Then she spotted Siren jumped to another ring which Hikari followed.

A/N: the reason I used Hikari (Japanese name), not Dawn (English name) is because Hikari and Siren was voiced by the same seiyuu.

Siren is way too smart here. Not just can guess that she is in Pokemon World, she used Hikari's appearance to guise herself.
