Forbidden Magic is something that nobody is immune or excused from casting. While it may be very tempting, it pays a powerful price when the user is finally caught. The punishment can vary between each type of Forbidden Magic.
HealingMagic cannot be used to heal others
This is the weakest of the Forbidden Magic due to it's punishment. If one is injured or sick, the user is unallowed to try to rid of it. They will gain the injury or illness themself and if a magic user, be banned for at least one week from using it and have their magic items taken away. This was shown to be used twice in Season 1, once by a non-witch or apprentice, and once by Hazuki Fujiwara.
ManipulatingMagic cannot be used to manipulate peoples hearts
This means, the user can't change the way someone thinks or feels about anything; whether it is something minor or something bigger.
If the user was to use this, their punishment will be accumulated depending on how many times they did it. They are put into a deep sleep reminiscent of a coma, but it is unknown what the time length is for just using it once. Onpu Segawa was the only person shown using this when she abused it during her time as an antagonist in Season 1. As a result she gained one-hundred years of slumber but was woken out of it after the others used their magic as a sacrifice to wake her.
DeathMagic cannot be used to revive the dead
This one is the most simple of the Forbidden Magic and if cast, the user will instead switch places with the dead person and die themself. Momoko Asuka used this in hopes of awakening Majo Monroe after she passed away from her illness. Momoko's crystal shattered and she didn't succeed in reviving Monroe. Because she used forbidden magic and broke her crystal, she lost the right to continue her witch apprenticeship; however the Queen gave her a second chance.
- Forbidden magic has been used a total number of 4 times in the series.
- In the dub, a 4th type of Forbidden Magic exists which includes using magic to change history. However it is unknown if this is legitimately classified as "Forbidden Magic" as the Ojamajos never used magic to change history thoughtout the series.
