Mmhhhh
Not very satisfated.
If a witch dies with a regret she will leave something terrible behind, they killed a witch and nothing happened, it seems like the curse only activates following the "natural" life of a witch ending, should have probably said that in a extra page before closing the chapter.
I presume they will make clear why heroes have magic allergy later.
Why the hero body didn't rot, dude looks like he just died.
Nina not doing anything when the blade was taken away, the person seemed to act on instinct but still put on gloves, the little sister excuse wasn't too bad, but doesn't work because is impossible the hero wouldn't have told her he had another sister in all their journey, there is a limit to Nina insecurities, I can imagine the doppelganger witch was tryingto find a way to break in the church and eat the body, but why use a dead person face? Or guards as escort? I can barely make it pass how she knew the sister face but it likely being on some booklet about the hero biography (weird the MC didn't knew).
Plot have several holes from the get go.
