I don’t really care much about pacing issues but...I can’t pin down the characters’ personalities.
And this no hate for the translators, more of a critique on the writing itself: I feel like the dialogue is hard to follow and doesn’t tell me much about the characters. Add to that that they aren’t drawn with a lot of facial expressions (in contrast with comics like Beware of the Villainess), and you end up with a story where the characters feel like the same person, just with different costumes.
