I Don't Mind One Bit Lv. 4
わたしは一向にかまわん Lv.4
I Don't Mind One Bit Lv. 4 is a Battle Cats stage in Vs Retsu Kaioh. It costs 90 energy and sends 7 enemy spawn lines — led by Retsu Kaioh (Enemy) as the boss — against a 80,000 HP enemy base, and clearing it rewards 8,037 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
