It's Not Your Fault (Veteran)
君のせいじゃない 超上級
It's Not Your Fault (Veteran) is a Battle Cats stage in Unit-13 Strikes!. It costs 100 energy and sends 5 enemy spawn lines — led by Unit-13's False Evolution as the boss — against a 200,000 HP enemy base, and clearing it rewards 14,100 XP. Its enemies carry the Eva Angel trait, so cats that target it do the most work here.
