This is Divione's special technique. She's got some kind of magnetic energy in her legs, and can release it through kicks. In this particular attack she uses all of her accumulated energy in one double-legged thrust.
Interesting enough, other people have claimed wanting to see her in distress. Pretty much like you hinted. She's a tough dominant character, with a lot of pride and ruthless, but anything might happen.
Well, that might happen. I had some ideas for her, however, not precisely owned by a male thugh, but let's see what happens. You can proceed however if you want. You should do, I think it good, more female characters, thugs or whatever, so there might be more chances. BUt you can ask that later.
