My Hero Academia Oc Kameyo

Kameyo didn't have the best childhood, to say the least. Her father died from a villain hostage situation when she was 6. Her mom did substance abuse untill she killed herself from it, when Kameyo was 9. She then was a troubled child, going from foster family to foster family. She wasn't the problem, though, in fact, she was a very nice child. It was the families. They all were bad families, always neglecting her in some way. She still kept a simile on, though. It was the last thing her dad told her to do. She has known cases of suicidal tendencies, but, because of her quirk, they have never worked. She has never admitted to being depressed, and she still will always keep a smile on her face.
Details:
Sexuality: bisexual
Age: 16
Quirk Name: Sun Dragon
Quirk: I am able to manifest a sentient dragon from his body that he can materialize and contract freely. The Dragon's energy is limited and can be drained by darkness. When it runs out of energy, Sun Dragon retracts back into my body.
The personality, strength, defense, and control of the Dragon depends on the light level. In Darkness, Sun Dragon is weaker and smaller in size, but still has considerable strength and defense and is easier to control. In bright light, Sun Dragon is much bigger, which grants it far greater strength and defense. It is even powerful enough to rip out and cut down multiple full grown trees with ease. 
Quirk Drawbacks: Sun Dragon is more difficult to control in the light, which might cause it to rampage based on its own free will.
Quirk Stats:
Power- 5 to 9/10
Control- 0 to 9/10
Understanding- 5/10
Other: This is literally just Fumikage Tokoyami's quirk, but less good, because its daylight based, instead of darkness, and it doesn't have any of the super-moves that Fumikage Tokoyami has.
