@Georg-Prime there's a difference between honesty and telling someone to fuck off, especially when you're already under suspicion of a capital crime and that someone has the power to be judge jury and executioner. She didn't even need to exist, trying to protect Rico from a knight and then mourning him openly in the knight's quarters would have gotten him to the stake, especially if they somehow found out Rico's connection with the Zombie Witch.
As for the girls, they fall mainly into two groups. They're either various degrees of petty, capricious or even cruel - The Princess, the Scorpion girl, Arsenio's crush, the girls Sauro "dated" and the Witch - or they're background - The mc's families, the assistant and The Macguffin of the series(Vivian).
But then again there's Betty and she's undoubtedly the best, so I'm probably way off the mark and it's probably just writer's block.
@iskaeil The demon he was consorting with was Rico, take the princess completely of the manga and he'd still be in deep shit for openly grieving for a demon that suddenly appeared in the knight's quarters. He even tried to protect him from the knight captain.
And again demons(any being that doesn't need a medium to use magic) are greatly feared inthe theocracy which, by the actions of a single witch that brought the capital to it's knees on a whim, we can see it's post-judice not just baseless hatred(though there's also plenty of that).
