Overpowered Magic

"Well, to be honest, I really do not know how to explain it. I think it is best to just watch." Sei answered.

I nodded and turned to look on stage. Sophie stood there waiting for the instructor to tell her it was fine to start. Once it did, I only saw Sophie point to herself and a light shine on her chest and then. She became see through…. "What is that!?" 

"I don't know. It's like she is there but not. The strange thing is, is that she can still attack while none of your attacks can even hit her. They just phase right through her. I have never seen anything like it before. She asked me to fight with her so she could train her magic, and no matter how much I tried, I could not land a single hit on her, but she could blast me with magic or swing her sword at me all she wanted. Although I do think she needs to manage her mana because I think this spell actually requires a lot."
