Yes, I did it! That's all the "clear using red casts only" stages complete! Managed with +21 Summer Lucy, +21 Belial, +21 Producer, +18 Monster Hunter Sandy and +9 Martial Arts Satan. Had to use deer shards to give Summer Lucy and Belial CC immunity for the initial aoe charm enemy Kimono Lucy uses on the final stage. Now I just need a proper green team for the last three stages of Railway to Hell and I'll have it fully S ranked.
