The Ayakashi Hunter's Tainted Bride
Nanao was supposed to marry the lord of her clan due to her strong spiritual power, but when she was taken and marked by an ayakashi, she became an outcast in her home and lost everything. When the famous Lord Benitsubaki, head of the highest onmyo family, comes seeking a wife, Nanao is told to stay out of his way. But when he saves her after she was misunderstood, he doesn't seem to fear her curse at all and tastes her blood before declaring boldly that she's the one he's been looking for! The abused girl getting taken out of her bad situation by a new husband trope has been done before, but I don't mind seeing it again, and the setting is interesting. Trigger warnings: abuse, implied rape, implied bestiality, attempted suicide.
