The strategy is simple: put everyone from the Angel Killer set on your team EXCEPT Ichimatsu. If you include Ichimatsu in your team and play during auto-mode, you'll be stuck at the stage for longer than 45 minutes. If you are missing any Matsu from the set (e.g. Jyushimatsu) use that Matsu as a substitute. Or you can use 2 of the same Matsu from 2 different event sets (e.g. Zombie!Jyushimatsu and Jyushiko). Activate the AP Max and Attack/HP^ and turn on both auto-mode and auto NEET cannon. I used the hijirisawa building, the fish looking one and the Dayon museum. You can use Totty's building if you don't have the museum. If you don't have either Karamatsu or Todomatsu (or both) from the Angel Killer set, you have to max level them to 60 from the zombie set, because they are the keys to defeating this stage. If you still lose this stage with this method, turn off auto-mode and spam all your units, but once you are close to the enemy base, focus more on sending out Osomatsu to activate the NEET and then keep sending out Jyushimatsu.
