The fight starts with 7 enemies: 2 Dark Dragoons, 2 Light Samurais, and 3 Light Paladins. After 4 enemies are defeated. 2 more Dark Dragoons will show up near the top left area of the map, and 2 Light Samurais past the brick walls. All enemies have negative slash resistances, and -60% resistance to Disable.
The Paladins mostly focus on defensive buffs, but they also have some area attacks, so try not to line up for them. You can send your tanks to go first into the Paladins, while sending the rest of your units to take down enemies from the sides so you don't get flanked.
Since there are no magic type enemies, you might be able to save a slot in your party and/or VC to put in some offensive fire power instead of getting some magic resistance or a magic tank.
