Not technically a dodge since it's in IaMP, but I was playing against Youmu in Reimu's Story Mode. Youmu was using her First Sign [Double Pain] attack, which turns Myon into a completely grazable body double of Youmu. I was cornered by both of them and, panicking, did a quick 6A.
It just so happens that Reimu's 6A is one of the few normal attacks in the game that grazes, so I went right through Myon's attack and ended the spellcard. :V
