Don't Act Like You Know Me
馴れなれしく名前を呼ばないで
Don't Act Like You Know Me is a Battle Cats stage in The Lost World. It costs 70 energy and sends 12 enemy spawn lines — led by Lost World Yuki (Enemy) as the boss — against a 50,000 HP enemy base, and clearing it rewards 10,575 XP. Its enemies carry the Floating, Red and Black traits, so cats that target them do the most work here.
