Bianca Avila Rosario, more often addressed without her middle name, is a long-time member of the fire clan. Most of the time, she's seen snacking on all sorts of cheap convenience store snacks. She appears to be Shane's best friend.
Bianca stands tall with wide shoulders and a slightly thick build. Because Bianca hasn't performed any form of medical gender transition, her body build leads many people to misgender her on the spot to which she does not complain to (but Shane would). She's usually in loose, comfortable patterned shirts and palazzo pants. From time to time Bianca dabs in makeup with assistance from Claudette, although she has yet to be bold to leave with any more than eyeliner.
Bianca is freeflowing and seemingly without a care in the world. The reality is that every minute detail matters to her--she memorises everyone's preferences, habits, and talking patterns to which she adjusts to fit to them accordingly. However, when she speaks she would more often than not sound like she doesn't have the passion in the conversation, and only members of the Fire clan are well aware of this attitude.
She can get very self-conscious when it comes down to her gender, and on worse days she would disappear for hours on end. On the outside, she prefers to claim that she faces no sort of dysphoria whatsoever.
When it comes to Bianca's history before entering the Fire clan, it seems that she has declined time and time again to share any details about it. Nobody truly knows why Bianca has joined the clan, or what her relationship with her family is like. What is obvious however is that Bianca sees the Fire clan as a form of a second family, and she cherishes them greatly like an older sister.
Many consider Shane and Bianca to be unseparatable best friends. They met upon Shane joining the Fire clan, which then led them to bond over being transgender; on most days they would go shopping and have lunch at the malls in the city together. Perhaps it's their understanding of each other's struggles that Bianca fully trusts Shane and vice-versa.
