So the man revealed himself rather than attempting a surprise attack. At least he had some balls. Or rather a giant metal ball that he was clearly threatening to use as a weapon should she advance into his range. Thanks to her ki her diamond could withstand blunt force impacts far better than normal diamond could, which would fracture instantly despite its very high level of hardness, but heavy impacts was still the best option to break through her enhanced diamond defenses. She'd have to be careful in blocking with a diamond sword of the thickness that she had created unless he was only of normal human strength, but she couldn't count on that until she had more information. That should be her first priority against a strange new opponent. She could tell he would agree with her based on the way his unusual eye was searching over her entire body. 

She showed no signs of discomfort over this, only shifting her weight nonchalantly onto her right leg, her left leg bent slightly, and her sword, now firmly in her grasp, was lowered to point towards his chest. The first reason this was no big deal was that it was a battle, so of course your opponent would look you over if they had any common sense. Second, she was completely comfortable with herself, exuding a ton of confidence in her gaze, so had nothing in the slightest to be shy about. She never got what the big deal was about all that embarrassment stuff, but perhaps some people just weren't as confident as she was. This line of thinking reminded her of that dragon girl she met earlier. Perhaps they had more in common then what she might have originally thought?...yeah, no.

"Odd you say that, seeing how we both must have seen plenty of women in the great hall," Ruchette countered. "Or are you just making useless comments to try and upset me?" She let out a little, sophisticated sounding giggle, like that of a noblewoman. "The odds of you facing one was around 30% or so...now what are your odds of winning here, I wonder?"

As she spoke she held out her left hand towards him as well, a jagged diamond chunk forming in the palm. After a second of forming what would amount to around a handful of diamond, she began to charge it in preparation to turn potential energy into kinetic and fire it off.  It would glow white while charging and would be as powerful as an average pistol after a second; not as powerful of a bullet the size of her diamond, but the diamond of this size having the same overall power that the much smaller bullet would have. It wouldn't be as good at penetration due to it's larger size, but that wasn't a big deal. What she was really wanting to do was test his abilities. Should he do nothing different during this time then she'd fire it off towards his center of mass. Should he try to do something then she may need to hold on to it a bit longer to use as a countermeasure.
