Swift Satsujinken
神速の殺人剣
Swift Satsujinken is a Battle Cats stage in Kenshin Himura, Battosai. It costs 110 energy and sends 11 enemy spawn lines — led by Kenshin Himura (Enemy) as the boss — against a 75,000 HP enemy base, and clearing it rewards 9,823 XP. Its enemies carry the Black trait, so cats that target it do the most work here.
