Here's a fun combo with this:
Immoral Fiber (IF) with high HP plus Valentine with high Meter Gain and Forbidden Procedure.
1) Fight with IF until she dies. Do a ton of damage with her SA.
2) Val tags in and revives IF with Procedure.
3) Tag back in Immoral. She'll die really quick. Do a ton of damage with her SA.
4) Val tags in and revives IF.
5) Repeat until everyone is dead.
