[4-Star] The Battle Cats - Sea Breeze Salon

This level is also pretty rough for 4-Star since you don't have Juliet or Catophone for the Boraphim. So you'll pretty much have to brute force your way through the Boraphim by spamming attackers alongside either a good A. Bahamut or some decent Ururun procs. Chill Cat and Cameraman are the main Area Attack units you'd want to use her since Cameraman is all-around useful, and Chill Cat is very good for the Nimoy Bore. Ramen is the only real meatshield you need for this stage as the other units can keep the Bores back well enough. The startoff isn't too bad if you throw in Elemental Duelist and Thaumaturge for the starting Bores. You could also just have higher leveled units if you want a much easier time at chipping the Boraphim faster while needing less procs or really good Bahamut chip damage. Slow Cannon really helps for keeping Bahamut alive just a bit longer. Nothing else much to add other than spawning Ururun early before you hit the base usually leads to having another Ururun ready to spawn during the actual fight. Note that because of the slow units in 4-Star it's really easy to reach Cat Limit and have a gap in your meatshielding.
