I added the Mermaid versions of Bianca & Summer to the Roles section. In the Mermaid Princess RP, Bianca & Summer are not a Pokemon Trainers or Pokemon Ranger, but are mermaids who are born in the Pacific Ocean instead, they're 16 years old each. These Mermaids are not part any undersea kingdom & are the cousins of Lana, Mallow & Lillie.
Bianca (Not a Pokemon Trainer in this RP Version) = sweet, airhead
Mermaid = Left, Human = Right

Summer (Not a Pokemon Ranger in this RP Version) = selfless, brave, and greatly cares
Mermaid = Left, Human = Right

Let me know if you're interested. In taking the roles of these versions of Bianca & Summer.
As for their mother in the RP, I may do her single mother. The backstory for Summer & Bianca's mother for the Mermaid Princess. Their mother would be thoughtful, loving and clever:
"Somewhere in the Pacific Ocean, under the sea, there was a beautiful mature mermaid who was trained in magic & a single mother, she had everything she could ever need along with her mermaid daughters, the mermaids were named Bianca & Summer, the cousins of Lana, Mallow & Lillie. When her children, Bianca & Summer turned 16, they were permitted to see the open seas & she would encounter a new world; a world of humans."
Summer & Bianca's Mother in The Mermaid Princess: Holly [age 36]


As for what mermaid village in the Pacific Ocean they're from, I'm working on it. Also, before they leave to see the open seas, she would be given a crystal or Pearl. So that way would keep in touch with their mother & call her anything comes up.
