I can't tell if the author was self aware about the MC or not when describing the yandere as a person pushing her desires onto others.
On a side note. If her holy magic can negate magic particles and she's blatantly stronger than the demon lord, why weren't the traps negated? Logically the traps should have been negated or destroyed by the barrier around him specifically made to block them. This isn't even logically consistent at all.
