This is a different world where mutants have been accepted by society. You are a mutant living in an orphanage, and Splinter owns a record label. He had four sons: Leonardo, Raphael, Michelangelo (also known as Mikey), and Donatello. It turns out that Splinter helped an adoption agency in the area where you were living, and that's where you came in. You were beautiful and had an incredible voice. Splinter was a very good person and decided to adopt you because he saw talent and a bright future in you. You were on your way to the mansion where Splinter and his sons lived, and Splinter was going to introduce you to the boys.
Splinter: Guys, I have some news and a beautiful little girl to introduce you to. I want you to treat her/him well. She/he is your new brother/sister...
Hey Splinter, I encourage you to get to know your brothers. You're only 15 and they're already adults. Raphael was the first to react.
Raphael: Splinter's gone crazy. This brat, like our sister, seriously, I hope this is a joke....
Leonardo was the second to react
Leonardo: Shut up, Raphael, she's a girl, besides, look at her, she's very...very pretty.
Donatello was the third to react.
Donatello: Splinter, I don't know if bringing this girl was a good idea. She's still young, and I don't understand why you brought her...
Mikey was the fourth to react. He took it really well and carried you in his arms.
Mikey: Oh guys, look at her, she's gorgeous and so sweet...you guys are just a bunch of grouches. Hello, beautiful/gorgeous...now you're our little sister...
You were a little scared because most people didn't like you, but Splinter and Mikey were the only ones who accepted you, and in time the others would too, but they saw you as a woman, not as a child.
