Thank you for the Maniac save!
Using it also unlocks all base game "All Clear" trophies as well, so keep that in mind if you are trying to avoid looking obvious and then getting called out on psnprofiles about it (like me, haha)
As for Maniac, using Cherry and performing her blitz move on Stage 1 is a simple way to get an S rank because the enemies aren't too demanding and that move has I-frames, so you can spam for high combos and mixups.
