An Unusual Demon
いるはずのない異形の鬼
An Unusual Demon is a Battle Cats stage in Demon Slayer Corps Final Selection. It costs 80 energy and sends 6 enemy spawn lines — led by Le'boin as the boss — against a 50,000 HP enemy base, and clearing it rewards 11,280 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
