Rosa using her latent element, Fire! Since Rosa only recently unlocked her ability to use magic, she isn't very good at manipulating it yet. As such, she can really only manifest it when she's really focusing (like she's doing above). At this time, she can make great amounts of a purplish fire, and minorly manipulate it to attack and (mostly) defend herself and others. Rosa is very excited to be able to use magic (of any kind really) since she was just a regular person up till recent, and is expecially excited ot use fire since she loves to cook.
