Theme/Subject: Hunting and killing demons and monsters in the Republic Era and Wuxia, respectively.

Character Tropes: ML is an anti-hero 'Chosen One' of suspicious supernatural origins. Skittish yet brave, inquisitive, and charming FL. Interesting, integral, and unexpected supporting characters who are at times cliche but not in a bad way.

Script, Acting, and Direction: A fast-paced, anthology-like series with overarching villains, natural character development, lots of lore, humor, intelligence, a sweet romance, and a sad ending.
