How did you get S Rank? I defeated all the enemies, got a 3 second avg defeat time, no recov, no hits, and the Bonus. But I still only get A+. I truly don't know what I could possibly do at this point. I've done the Tutorial mission upwards of 30 times at this point.
just keep cancelling when they're having the H scenes, if you let them repeated over and over, it will give you more points—the more enemies the better from what I know.
