Ash was on a trip with his Kalos travel companions but he didn't pay much attention to them. Serena was very frustrated because of this. Clemont was wondering why. Bonnie said that Clemont was too dense.
A star was flying across the night sky. "Oh pretty twinkle little star how I wonder where you are please make my wish come true all I want is for Ash to become a more sensitive person so he can understand my feelings." Serena prayed. Arceus heard her request and granted her wish. "May the girl in sorrow finally gain true LOVE" Arceus said.
On the next morning...
"AAAAAAAAAAAAAAAAAAAAAAAAAAA!"
Everybody gathered around Ash's tent to see what he was screaming about. Out of the tent... a girl appeared! She was just like Ash except she had longer eyelashes, longer slender legs, naturally red blushing cheeks, a more attractive tanned colour of skin and longer shoulder length hair, also a very large size breast and a sexy body.
(From now on I will refer to Ash as Ashelina in order to avoid confusion)
Ashelina's hands were shaking.
"G-guys, wh-what the hell happened to me!?"
Serena at first was shocked but she immediately understood that this was her dream come true. Now that Ash had turned into a girl he could finally understand the concept of romance because now he had been transformed into a more sensitive person just like Serena wanted to.. She still loved Ash even in this form because it's the person that matters and not his gender. She knew that even a change of gender would not stop Ash from becoming a Pokemon Master.
Serena was planning on eventually seducing Ashelina , step by step. She evilly grinned and quietly laughed while nobody was watching.
"Hahahahahahaha... HAHAHAHAHAHAHA! Ashelina will be mine!"
