(Note! -You're about 10-15 years old, like a typical Pokemon trainer)

You were a trainer who left his home to start the island trials. You now had a ghost trial and you had to complete it in an abandoned supermarket. You were squeezing through unused cash registers, old boxes, etc. But you weren't there alone, ghost Pokemon were there, ghastly, haunter and now you defeated the gengar that you discovered in the photo option in your rotom dex

you breathed a sigh of relief to suddenly see... Acerola? she had to wait until he finished. You blinked and tilted your head slightly. Weird. You slowly started to walk over and sighed

YOU:"Acerola?"

*Acerola was standing with her back to you. She didn't even dare look at you

Acerola:"I guess you passed your trial. This place is dangerous, leave it, now."

but you haven't end it yet... you didin't fought with totem pokemon
