Personality
Funny, Sassy, says "yush" and "nu" and "yus" a lot. Aurora says those a lot too, but only around Estella. She can also be really evil and creepy, with the fact she has a Garden Of Hands.

Becoming Rin
Estella, at the time Bubbles, decided to be twins with Boomer by being Rin Kagamine and he would be Len Kagamine. They took the form of it, but Estella uses the form of Rin a lot more then Boomer use's his form of Len.

Daughter Of Diego
To make the two more like twins, Rin went to Diego and got adopted by him as she and Boomer pretended to be twins.

Story of evil
Becoming Rin, she took the role of Princess Rin inside of the story "Story of evil", which made Boomer be her servant. They relived the story and once they finished that she carried on as simply the ruler.

Introducing.. Aurora!
Aurora, at the time Brat, always bugged her counterpart and eventually took the role in Vocaloid as Hatsune Miku. She became enemies with Bubbles. Well, more of frienemies, but Rin would always try and get Aurora's hands for her hand garden. Up to the current days, Aurora and Rin are close friends alongside Rin and Boomer being close friends.

Real kid of Diego
Eventually, Aurora became really twins with Boomer due to Diego's Cosmic powers. As soon as Estella was with Aurora, Aurora quickly brought herself and Estella with her, to Diego and had Estella become triplets with Boomer and Aurora. Aurora wanted Bubbles/Rin to get a new name for fun, and to match the fact Aurora has a space name, Rin was given the name "Estella".
