MELTY BLOOD: TYPE LUMINA

At first I was a bit confused as to what a 'perfect' is, but it means that you need to win five total rounds without getting hit. A good strategy (in my experience) is to set CPU to 1 difficulty and use the A B C C C C combo ( X Y B B B B) A few times, then hold down A to shield until they attack, then counter (by pressing X Y or B right after their attack hits your shield) and use that into a combo, then repeat that until you win.

The opponent blowing you back by activating their heat does not mess up you getting perfect.
