DMC5: DMD Mission 13 S Rank, No Damage (Nero)

Yeah, didn't really know what I was doing in this one. Figured I'd try to clear the enemy groups on most floors, but generally didn't have that much of a thought out breaker setup and whatnot. Was just ready to get through this and tackle the other two Nero missions I have left (8 and 15). I'll come back and do V and Dante's versions of this when I get around to doing their missions.
