Given her penchant for using magic, Irona must have her powers nullified before she can safely be bound, otherwise she will find a way to completely turn the tables and take charge. She is not afraid to turn men into women as part of her ironic punishments, so it's best to make sure she never finds out who her captive is due to her tendency to punish those she feels has wronged someone. But since she isn't physically strong, she's easily subdued once her magic is sealed. Both her bust and butt are part of her best features and weak spots while a good, face-covering gag that just barely reaches the beauty mark under her left eye are the best to use. However, keep her blindfolded and don't identify yourself if you want to avoid her later ire.
