I'm trying to find a manga that I once read about. The hero's party, after defeating the demon king, got cursed: the hero turned gay, the monk turned young, one turned into a girl, and the princess turned evil. They are trying to find a way to get rid of the curse while also trying to find the princess that turned evil.
The manga was black and white and I'm pretty sure that they got help from a witch that cured one of them but there was a time limit I think. I think I read it in August or early on. I don't remember the name of any character but I think the hero's name was Arthur.
