Why Not Become a Demon? Lv.18
お前も鬼にならないか？ Lv.18
Why Not Become a Demon? Lv.18 is a Battle Cats stage in Akaza Strikes!. It costs 140 energy and sends 12 enemy spawn lines — led by Akaza as the boss — against a 1,060,000 HP enemy base, and clearing it rewards 12,502 XP. Its enemies carry the Aku and Black traits, so cats that target them do the most work here.
