Arcana Heart 3

Thought I'd include the method I used to get this cheev on my first attempt

First I set the A and B button to be on 1 button (I picked RB but you can pick whichever button you prefer) through Options>Button settings

I went to versus with a 2nd controller, picked simple for Maori, spammed moves till I had 2 bars as the 2 moves needed use 1 Arcana Gauge each,

Then I pressed back and A+B (in my case the RB button) and as the move was being performed I quickly pressed down and A+B (again RB in my case) both moves hit back to back and cheev unlocked

Select Versus Match and choose Maori. This Achievement is awarded by hitting the enemy in one combo with all of your sisters (3 total)

This is easily done by performing the Taima No Zuikaku followed by the Hama No Shishiku Move. It requires a little bit of timing and two Arcana Gauge but if you set the time to infinite and for 5 rounds it should come in due time.
