Yuna rubbed the eye tattoo on her forehead. It wasn't the first time it had appeared at the emotion of annoyance and borderline anger and wouldn't be the last. Its appearance signified that Yuna had intaken some of her father's divine power and if she did not use it, it could literally eat her from the inside, so when a person suggested sparring with her to vent her anger she jumped on the opportunity.
Of course Yuna hadn't taken in a lot of energy from her father, and as a result her abilities would not be as strong as they would be at some times, but she still was capable of doing lots of damage if her opponent wasn't careful.
"I wouldn't have accepted your offer if I needed something to beat on, I'd rather we spar. Though I'm gonna have to warn you to be careful when taking my punches, you may be blown away by them."
Yuna opted to keep her shoes on as she was a boxer through and through. She didn't know any other fighting style and didn't plan on using anything else for the time being. She did, however take off her jacket and rolled up her sleeves.
Yuna got into a ready stance and her tattoo on her head seemed to darken a little almost as if anticipating a fight.
"I am ready to spar when you are"
