 * 1) Her signature skill is more likely to be Linear, not Flashing Penetrator, which was only mentioned maybe two times in the entire series.
 * 2) Flash is written as 閃光, flashing as フラッシング. The two don't even sound alike.
 * 3) The only explanation for her name that I could find is: "Also, contrary to her delicate frame, Asuna was the sub-leader. Her sword skill was so exceptional that it had earned her the title «Flash». " In this case, "sword skill" refers to her skills with a sword in general, NOT a specific skill.
