Sekia Goshoha (Deadly)
炸裂！赤鴉豪焦破 極ムズ
Sekia Goshoha (Deadly) is a Battle Cats stage in New Challenger. It costs 300 energy and sends 12 enemy spawn lines — led by Akuma (Enemy) as the boss — against a 750,000 HP enemy base, and clearing it rewards 305,500 XP. Its enemies carry the Black trait, so cats that target it do the most work here.
