Though the two would initially find happiness, a threat from the terrifying fox-demon Hagoromo Gitsune would get in the way of their relationship. In the present, Rikuo has taken his rightful place as the heir to the Nura Clan. While he has accepted his youkai side, he must continue to maintain the secret of youkai, a difficult task when faced with the Keikain onmyouji clan and his youkai-obsessed friend, Kiyotsugu. Even so, Rikuo will do what he must to protect those important to him. The reappearance of the sinister Hagoromo Gitsune marks the start of Rikuo's most fearsome trial yet. The frightening creature bears a personal vendetta against his family and will stop at nothing to see her dream come to fruition. The world stands at a precipice, an all-out war that will drag Rikuo centerstage. [Written by MAL Rewrite]

After the death of his parents, Yuuto Amakawa lives a pretty ordinary life in the city. The only problem he has to worry about while attending school alongside Rinko, his next-door neighbor, is his cat allergies. That all changes on his sixteenth birthday, when an Ayakashi—a supernatural creature—attacks him for the sins of his ancestors. Luckily, he is saved by Himari, a mysterious cat-woman with a sword, who explains that Yuuto is the scion of a family of demon-slayers, and she is there to protect him now that the charm that kept him hidden from the supernatural forces of the world has lost its power. Omamori Himari chronicles Yuuto's dealings with the various forces of the supernatural world, as well as the growing number of women that show up on his doorstep, each with their own dark desires. Will Yuuto be able to adjust to his new "exciting" environment? Or will the ghost of his (ancestor's) past catch up with him?

After centuries of antagonism and misunderstanding, the Japanese finally welcome youkai into their community. In an attempt at species integration, normal children begin attending school with paranormal creatures who are quite humanoid. Shingo Ohashi finds himself developing feelings for Hatoko "Petoko" Fujimura, a half-youkai half-human girl whose powers are: uncontrollable cuteness to enchant those around her (similar to a low-power succubus), get stuck to any other person who touches her bare flesh (cured by her falling asleep), and the ability to disappear even at the molecular stage (which she can for the most part control).
