Tsuki (Model)/Rosemary - Tsuki was scouted as a young child to become a model and has become a huge sensation in Kanto. Her mother acts as her mother and keeps track of every little detail of Tsuki's life, more like a drill sergeant than a mother. Tsuki loves working as a model, but when she was young she always wanted to be a pokemon trainer. When she was eleven years old and she was just starting to become famous as a child model, she found a shiny vulpix that had gotten separated from its family and wandered onto Tsuki's property. Tsuki took care of the lost vulpix, who she called Haru because she was a beautiful yellow like the sun. Haru became attached to Tsuki, and even followed her to one of her shoots. One of the photographers got the idea to include Haru in the picture, and soon Tsuki and Haru became a dynamic modeling duo for both human and pokemon fashion. Tsuki worked as a model until she was 18, but by then her mother was becoming more and more strict and the fun times she used to enjoy as a model were becoming few and far between. She made arrangements in secret from her mother and after one of the biggest shoots of her modeling career for the most famous Fashion Designer in Sinnoh was completed, she quietly slipped away.

To disguise herself, Tsuki dyed her hair blonde. But before leaving Sinnoh she and Haru went to a place that she had overheard some of the workers at the shoot talking about. Rumors had been going around about a strangely colored Shinx wandering down a forest path and how several trainers had tried to catch it but had been unsuccessful. By pure luck, Tsuki (who had changed her name to Rosemary to try and hide her whereabouts from her mother) stumbles on the shiny Shinx and she and Haru are able to befriend it. Shinx hated being different, but seeing Vulpix was a different from normal color made him feel like he belonged and he went along with Rosemary as her second pokemon.

Rosemary made her way to the airport where she chances to meet up with Brock, Ash, and Dawn in the middle of their pokemon journey through Sinnoh. They had come to the airport to welcome Professor Oak who was going to give a special presentation. Rosemary, who was waiting for her flight to go to Alola, ended up chatting with the group of friends. Dawn immediately recognized her as the model Tsuki because of Haru, even though she had dyed her hair, and asked her for an autograph. Surprisingly, when Brock inevitably hits on Rosemary, she actually finds him charming. Since she is a model she is used to being called beautiful by strangers, but she finds Brock's energy enjoyable, and she actually flirts back with him, causing him to nearly faint from shock. Her flight is called though, so she invites the group to write to her whenever so she knows how their journey goes. Then she leaves a broken-hearted Brock behind to go off and start her pokemon journey.

Shiny Vulpix (Haru) - Her first pokemon companion. Haru and Rosemary are inseparable, and as they go on their pokemon journey and take on the Island challenge Haru becomes a reliable battling partner. Her personality is a little on the vain and petty side, but once she warms up to some she is as loyal as can be.

Shiny Luxio - As a Shinx he is very standoff-ish from his past experiences. But as he evolves and gains experience throughout the island challenge, Luxio becomes an energetic and determined pokemon. His personality borders on the arrogant side, but he loves Rosemary deeply and becomes as docile as a deerling whenever she pays him attention.

Alolan Raichu - On Melemele Island Rosemary captured Pichu after she tried to swipe some of Haru's pokefood. A very indignant Haru chased after Pichu, ending up crisping the food that Pichu tried to steal and then dousing the little rascal in a powerful flamethrower attack which left her knocked out and ready for Rosemary to capture. Haru and Pichu had a terrible relationship since Haru was an expert at holding a grudge, but as she evolved into a Pikachu and eventually into a Raichu, these two became as close as sisters.

Vaporeon - Rosemary was gifted an Eevee egg by a daycare worker on Akala island. After much debate and several tests, she decided to evolve Eevee using a water stone into Vaporeon. Eevee had been the little sister of the group since she hatched from an egg, but once she evolved, her personality changed dramatically. She was calm and serene, but completely merciless in battle. Her stamina was also through the roof, so she became a pillar on Rosemary's battling team.

(Honestly, I don't remember the other two members of Rosemary's team. I don't think I ever decided how this story ended because I couldn't decide if Rosemary was going to end up with Brock or a handsome Ace Trainer. :P So that's all I've got for her story)

boredBRAIXEN This is the story that I was referring to when I said I had a thought to make an OC and Brock fall in love :P
