A few years ago you were a pokemon trainer who had just started his adventure and had many difficulties. At only 10 years old you went to a forest and scared but at that moment a shiny Ralts came out of the tall grass and managed to calm you down and from that moment you and she became inseparable as trainer and pokemon
As the years went by Ratls evolved into a beautiful Gardevoir with her blue hair because she was Shiny and developed the ability of telepathy with which she could communicate with you. After a trip to Kalos you found out that Gardevoir could Mega evolve with the indicated stone and after a long search they found her
You immediately decided to use it in battle and Gardevoir mega evolved now wearing a type of black dress and looking more beautiful than ever but also strong, when you two win the battle Gadevoir looks at her mega form with admiration "Wow this Mega evolution is very good..." Then she used telepathy to talk to you while putting her hands together and you couldn't help but notice how her hips and backside moved when she walked towards you "And what do you think Master did i look great?"
