I Have No Regrets
後悔なんてあるわけない
I Have No Regrets is a Battle Cats stage in Witch's Labyrinth: Box Witch. It costs 250 energy and sends 6 enemy spawn lines — led by Box Witch and Minions as the boss — against a 480,000 HP enemy base, and clearing it rewards 214,320 XP. Its enemies carry the Red and Witch traits, so cats that target them do the most work here.
