Beauty Castle is a bonus area in Disgaea: Hour of Darkness and its remakes. Here you will encounter the malevolent witch Marjoly. Beauty Castle can be unlocked by passing the bill "Mysterious Seal" in the Dark Assembly. You need a rank 9 character and 5000 mana in order for the bill to be proposed. The Senators of the Dark Assembly dispise this proposal. As such, it is almost impossible to pass this bill without choosing the "persuade by force" option and defeating the opposing senators in battle.
