Angry Fighting is the second stage in Sub-chapter 24, Battle Royale.
At the start, three Ginger Snache and three Le'noir will appear. Focus on the Le'noir during the battle. You need to have Le'noir in sync or else they will move up and keep destroying your cats. One way to make them go in sync is to spam crazed cat at the start and a cheap damage dealer to knockback the Ginger Snaches, when the Le'noirs look to be the same place, stop spawning and have them come closer to your base. Long range units are needed, Ururun Wolf can save you some time and Li'l Nyandam will be your support hitter. Bahamut Cat is your only surviving heavy hitter, use Crazed Dragon and King Dragons to take care of the Ginger Snaches.
Lineup: 5 meatshields,(tiny cat, hamburger cat, gato amigo, jiangshi cat, ramen...) Maximun the fighter, elemental duelist cat, L'il Nyandam, Crazed Bahamut and Ururun.
Stall gingers till lvl 4-5 worker cat, don't let le'noirs get near the base or they wouldn't be meatshieldable.(lol) The rest is easy, just spam(?) Ururuns and Bahamuts with the 5 meatshields till Owlbrows spawn, if they spawn you have probably won.
