The main character and the namesake of the story. 
Flare is an Afro-Latina young adult women who is filled with firey passion. She loves her family and friends above all else and will protect them to the best of her ability. She's not weary of a fight, and most of the time she starts them. She's impulsive and rash. But oddly responsible. She knows that in a fight if she falls, what she cares about could go up in smoke. And that's something she cant let happen. Not again anyway. She is a big anime and cartoon enjoyer. She tends to curse in Spanish if she is irritated enough. She has a positive big sister personality. Something that warms the hearts of whoever is near. She fully aware of how cool she is. 
 I'm open to her having a Spanish accent but one isn't required. Knowing some Spanish would also be nice.  

Characters similar to her are: Miriko (My hero academia), mereoleona (black clover), maki (jujutsu Kaisen), Ryuko (kill la kill)
