Why Not Become a Demon? Lv.15
お前も鬼にならないか？ Lv.15
Why Not Become a Demon? Lv.15 is a Battle Cats stage in Akaza Strikes!. It costs 130 energy and sends 12 enemy spawn lines — led by Akaza as the boss — against a 850,000 HP enemy base, and clearing it rewards 11,609 XP. Its enemies carry the Aku and Black traits, so cats that target them do the most work here.
