About five minutes...that's how long Persia could stay in her VamPanther Mode, probably because it had somehow merged with her Retractable Anima instead of being a seperate Vampire Mode transformation. In comparison to my Vampire Mode, her speed and strength were just about two thirds of mine...more specifically, my Vampire Mode is fifteen times my normal state, and she was currently ten times my normal state in terms of speed and strength, plus her flexibility was even greater than before.
Which meant that once she learnt how to use the Accelerate Cross...she could reach a speed that was forty times my normal state. Holy crap...
