Momiji doesn't want to be the chosen one, doesn't want the blood that makes her special, doesn't want any of this. The show lets her hate it while fighting anyway. That friction between obligation and actual desire runs through every episode, making the monster-of-the-week structure feel like a girl getting pulled deeper into a life she never asked for instead of a hero's journey playing out on schedule. The romance with Kusanagi matters because it's the only thing she might actually choose for herself. Early 90s charm keeps it from getting bleak, but don't mistake the comedy for lightness. This is about a girl learning that having power doesn't mean you get to decide how it's used.
Momiji lives an ordinary life until a chance encounter reveals the truth: she carries the blood of the Kushinada clan, an ancient lineage tied to a supernatural duty. Across Japan, plant-based demons known as Aragami are awakening, spreading destruction and chaos. Only someone with Kushinada blood can stop them, which means Momiji has just become humanity's last defense. Caught between her normal world and this impossible responsibility, Momiji joins forces with TAC, a government organization dedicated to fighting the Aragami threat. There she meets Kusanagi, a fellow operative whose connection to her bloodline runs deeper than either of them initially realizes. Together they investigate the creatures' origins while uncovering mysteries about Momiji's family and destiny. The action flows alongside genuine character moments and humor that keeps things grounded. Momiji resists the role fate has chosen for her even as she steps into it, creating tension between her personal desires and her growing powers. The Aragami threat intensifies as answers become fewer and the stakes grow heavier.
