Biological Hourglass

全力！結婚相談所

Biological Hourglass is a Battle Cats stage in Lovesick Again. It costs 250 energy and sends 7 enemy spawn lines — led by Director Kurosawah as the boss — against a 350,000 HP enemy base, and clearing it rewards 22,325 XP. Its enemies carry the Black and Metal traits, so cats that target them do the most work here.
