Have you tried the Kingprotea CQ? I had to brute force the preceeding fights but not the battle with Kingprotea herself. Team was Jeanne, Support Scathach, Skadi, Mash, Cu, and I forgot who the last one was. 
The fight with MONSTER (Shiki) I used Medea, Mash NP2, Support NP2 Tamamo, Santa Altera, Jack, and Chloe.
