The enemies themselves aren't too difficult on this map, but the positioning can be a bit annoying at first. Thankfully, the red mage on turn 2 does enough damage to put Soren in WoM range to help keep the dancers out of enemy range.
The red tome cav on turn 6 can be annoying if Soren doesn't have Growing Wind charged up, so Spur Atk and Drive Atk can help if not.
