The Aku Realms — Stage 47
北海道
The Aku Realms — Stage 47 is a Battle Cats stage in The Aku Realms. It costs 200 energy and sends 13 enemy spawn lines — led by Mr. Mer as the boss — against a 900,000 HP enemy base, and clearing it rewards 14,800 XP. Its enemies carry the Red and Aku traits, so cats that target them do the most work here.
