Dual boss, and one of the hardest Stage 5 bosses IMO. They have some pretty challenging spells and the nonspells are very disorienting, especially the 2nd non. The biggest problems are their combination patterns when they start to desync from each other, causing very weird overlaps.
Common consensus seems to be to face Mai for the first spell and Satono for the second, as they're easier than their counterparts.
The stars on Behind Festival are super gross, they're constantly moving and stopping and changing trajectories so it becomes very difficult to try and predict safe areas. The best consistency I've had with it is when going for really wacky speedkills like I do here.
The final should also not be underestimated, I lost quite a few runs there.
