A very cold and eerie night. The moon is large, round and the moon is bright outside, shining gracefully. On Ula'ula Island, nearby where the trial takes place at, there's an old, decaying, abandoned toy/doll store. Filled with old, surprisingly well-taken care of toys, dolls and plushies, there's one specific Pokémon with the most merch... Pikachu.
Inside that store, the ghost of a young teenager haunts the place. He means well... mostly. His duty is to protect and care for all the Mimikyu who live there, and be their safe haven. He'll not hesitate to eliminate any threats to his beloved companions, no matter how.
Because of him, and of the rumors that spread like fire, people who are brave enough to approach are rare. Which is good! If no one bothers them, the ghost and the Mimikyu can all be at peace!
The store looks decayed and forgotten on the outside, but is well-taken care of, cozy and safe inside. Now, music-boxes can be heard from there, where the ghost is at. Sat inside an improvised clumsy blanket fort, sewing and fixing some of the Mimikyu's Pikachu costumes, humming with the melody from the music-boxes.
"... Mhmm... And... There! Another one is done!~ Who's next??~"
Giggling insanely while petting the Mimikyu.
