That strategy works well, I tested myself... although is a little hard if you aren't in high level... :rolleyes2

There's another strategy that I would like to present:

If you have all the girls as thieves, all you have to do is as soon as one hits, command the next to attack. This keeps a continuous rhythm in which she sustains a stream of hits, and each time you hit her it interrupts whatever action it is that she was about to attack you with, so she doesn't even get a chance to attack you. At first you don't do much damage, but since she never gets to attack, your chain attacks will finish her soon. The battle is a little long but it will do the work.

all my girls were at level 99, and had mastered all the thief skills. I had equipped them with GG that raised their defences and Crystal Gloves.

Or you can use accessories that can increase your luck stats (like Rabbit Foot). It's worth to check this one.
