The Aku Realms — Stage 39
栃木県
The Aku Realms — Stage 39 is a Battle Cats stage in The Aku Realms. It costs 170 energy and sends 9 enemy spawn lines — led by Fallen Bear as the boss — against a 700,000 HP enemy base, and clearing it rewards 12,400 XP. Its enemies carry the Alien and Aku traits, so cats that target them do the most work here.
