Collaboration Stages · Stage 3
in JAPAN
in JAPAN is a Battle Cats stage in MIKU EXPO. It costs 120 energy and sends 6 enemy spawn lines — led by Kagamine Rin & Len (Enemy) as the boss — against a 30,000 HP enemy base, and clearing it rewards 62,040 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
