Another Mystery Girl
もう一人の少女
Another Mystery Girl is a Battle Cats stage in The Lost World. It costs 50 energy and sends 10 enemy spawn lines — led by Lost World Yuki (Enemy) as the boss — against a 15,000 HP enemy base, and clearing it rewards 7,050 XP. Its enemies carry the Red and Floating traits, so cats that target them do the most work here.
