the last couple comments gave me a chuckle lol. it'll get scary real fast if its more than sibling love xD, though i half expected a "then i'll make onii-chan come" . but she still sadly comes to the problem that she's really only got a semblance of free will thanks to the demon protection drugs. her and red of done so damn much for people and the world i want both living with lit happily, maybe randomly wrecking bandits or demons' shit that try to mess with the town.
Not just her a lot of people have a form of curse on them.
Brawlers become more violent.
Sage start to lust after knowledge.
as just 2 examples earlier chapters gave a few more
I like that Red isn't a hypocrite. He doesn't tell her "no, you're the hero, you have to continue on the journey". He accepts that she said fuck it, just like he did, and he will support her.
