The Reincarnation of the Strongest Exorcist in Another World isn't the most groundbreaking, and its animation is average, but it brings enough unique elements to the table to make it worth watching for fans of the genre. Seika is a likable protagonist, the onmyoji angle is a fresh twist, and the writing is smarter than most isekai. If you're looking for a solid, character-driven isekai with a unique premise, this is worth a watch. If you're burnt out on the genre, it won't change your mind.
