Battle Fantasia

In order to make this achievement easier I suggest you change the settings to very easy difficulty and infinite time. Infinite time in part due to the fact that the animation for this grab is kind of slow and I had a few matches where I only needed a couple more grabs but the timer ran out.

Let's get started! Begin arcade mode with Olivia and decide whether or not you would like to attempt this on the first opponent. I had no preferences, however some characters could be less annoying than others. Regardless of who it is, the grab will only do one damage per execution. That said, you'll have to lower the opponents health quite a bit before attempting this. Spamming the half circle towards + C move is a good way to lower their health quickly. Once they're down to about 200, simply spam A attacks (in game command, may vary depending on control scheme). Take note of how much damage it does and keep using it until one more attack would kill them.

Now you'll spam the grabs. In order to do this, do a half circle away and A. She should lean in and give them a kiss and it will do one damage. If you time it as they rise you can get them in a loop though they'll usually catch on after about 3 grabs. If you finish the opponent with this grab, you'll have your achievement.

this must be done in arcade with olivia.
shall we dance does exaclty 1 damage all the time, so you have to weaken the enemy to a single digit number and use shall we dance enough times.
