"Cheryl." you say into the watch.
At first, nothing happens. You laugh at yourself, unable to believe you fell for the old man's trick.
"Of course, who'd think that possession'd actually wo-" you drift off. You suddenly start feeling light headed. A white light clouds your vision. You feel as though you're floating in a fog. Then, as suddenly as the sensation came, it disappears. Your vision slowly returns, but you feel, different, somehow.
You look around. You're inside a dark forest. You see a Blissey standing in front of you. You look past the Blissey, noticing a figure standing there, a with a bowl haircut. The figure's pokemon, a Hitmontop, suddenly rushes out, striking the Blissey sitting before you. It falls over, knocked out. The figure begins laughing.
"Hahaha! Now you're coming with us!" the figure states.
You look around, noticing no one else around you. You begin to speak out, suddenly realizing that your voice is way more feminine than before. You look down, noticing that you're wearing green, large boobs sitting on your chest. A gust blows, and you feel the wind rush up the skirt you're wearing.
"Holy crap! I'm Cheryl!" you yell out loud. The figure across from you looks confused, then quickly gets back on topic.
"Don't try acting your way out of this!" the figure yells. "Go Hitmontop!"
The Hitmontop then rushes straight at you. You put your arms up in defense, but it's all in vain. You're knocked unconscious as you fall upon the ground.
You wake up inside a building. You look down at yourself, you're still Cheryl.
"Ow. What did I get myself into?" you ask yourself. Suddenly, a voice echoes across the room.
"Awake, now are we?" a figure similar to the one in the forest asks. "Now, will you join us?"
"Join what?" you ask.
"Don't act dumb. If you don't join, we have other ways of changing your mind." the figure states. "So I'll ask again, will you join?"
