@razyackerman I'm pretty sure that most Japanese manga use forbidden as in a magic that is either extremely difficult or extremely dangerous, and not forbidden as in you should never use it
Sometimes plot is unnecessary in the comfort manga story. I would've been happy if they went to the demon lord and its now that demon chick that was being chased by the human/demon guy. Or hell the guy himself since she made a joke that she can only marry the demon king and he went and beat the previous guy up and took his throne. And she's just sitting there with the O_O face.
so that's all there was to it?? Is the idiot killing himself by healing others? I thought it was something more like out of his control, but the fact that he is doing it himself just makes this stupid.
