This and the next videos will show the best possible solution for these gimmick-based doors for Vision Quest.
Now this is quite likely the most gimmicky out of the five doors. It requires a bit of luck that Magarudyne does not miss the Musha enemy weak to it. So do not be discouraged if you fail the first time around. The basic gist for the first turn in this is that the protagonist removes Makarakarn from the enemies by using Sexy Dance. There is a chance that all 3 repels will miss (Will be elaborated later). Yukari uses Magarudyne twice when she hits the Musha with the Wind weakness. Akihiko uses Marakunda. Then Mitsuru either uses Dis-charm to remove the charm from the protagonist using Sexy Dance. Or she Mind Charges if the protagonist is not charmed. The next few moves will boil down to:
Protagonist uses Magarudyne (Twice if the Musha weak to Wind is not dizzy)
Yukari uses Magarudyne
Akihiko uses Marakunda if it runs out from the enemies. If it is still active, use Maziodyne
Mitsuru uses Mabufudyne
This keeps going. Do not try to remove their buffs or your debuffs. Do not remove the poison when they are using it on you after the All Out Attack. You can revive fallen allies. Keep on attacking until they all die. That is all.
