Oni no Hanayome

Yuzu Shinonome's family treats her like she's invisible. Her sister Karin married a powerful fox spirit, which brought the family status and prosperity, and now everyone reminds Yuzu daily that she doesn't measure up. She's the overlooked sibling in a world where ayakashi — supernatural beings from Japanese folklore — live alongside humans, and where being chosen as an ayakashi's bride is basically hitting the jackpot. Then one day, Reiya Kiryuuin, heir to a prestigious oni clan, shows up and tells Yuzu she's the bride he's been searching for. Suddenly the girl nobody wanted is at the center of the ayakashi world's attention, and she has to figure out what that means for her, her family, and this centuries-old supernatural society she's been pulled into. The setup is very much a Japanese folklore Cinderella story — neglected girl, unexpected proposal, a whole new world opening up — but it's grounded in some genuinely interesting family dynamics and questions about self-worth. If you liked the human-meets-supernatural romance of Kamisama Kiss or the slow-burn emotional weight of The Ancient Magus' Bride, this is in that lane. There's also a Natsume's Book of Friends quality to how the show treats its ayakashi world-building, where the coexistence between humans and spirits feels lived-in rather than just decorative. The tone leans romantic and warm, with enough personal stakes around Yuzu's growth to keep things from feeling too fluffy.
