Solar Dragon

Solar Dragon (ソーラードラゴン Sōrādoragon) is the Quirk used by Yoake
Description
Solar Dragon is a quirk comprised of two components, these being the Fire or Solar and Dragon.
Fire/Solar: Yoake's first component is fire, which similar to Shoto's fire, she can create and use however she needs. Although one trait to her fire, is that she needs to absorb solar energy to use the fire, to tell how much fire she has, the inner side of her hair, in the back, will grow yellow, the brighter the yellow, the more energy she has. 
Dragon: Yoake's second component is dragon, this component like the name suggests, takes traits from the mythical beast known as, the dragon. The first notable trait, has to due with her fire, is that she can breath fire, which comes from her dragon component. The second notable trait, is that Yoake can take traits from a dragon an use them on herself, similar to Ginko's Animalization. These traits can include a dragon's wings, claws, tail, etc... 
Weaknesses
One of the major weaknesses of Yoake's Dragon component, is that, if she uses too many dragon traits for too long, she'll begin to lose control and become a human-dragon hybrid, with no sense of friend and foe. To tell, if she's changed, she'll begin to grow horns, her pupils will change and become thin like a cat's, and finally she'll grow scales that have a grey-ish, green-ish hue, to stop her transformation, there are only two ways, to pour blood into mouth, and say "Dragon, return!" or have someone she loves come up to her eyes, and she'll snap out of her transformation. Although, she can grow scales normally, and you can't mistake this for her transformation, to tell if she has grown them out of her transformation, check their hue, if they are completely grey, they are normal, if they have a grey-ish, green-ish hue, they are transformation scales.
