Burning Blue
炎上する青
Burning Blue is a Battle Cats stage in Laboratory Island. It costs 250 energy and sends 12 enemy spawn lines — led by Koronium as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 401,850 XP. Its enemies carry the Relic and Metal traits, so cats that target them do the most work here.
