Demon Love Spell [Manga]

The series follows Miko, a young shrine maiden living with her family. She’s frustrated that she’s unable to contribute much to the family business, as she has little apparent supernatural abilities and cannot easily see or banish spirits. Miko eventually runs into Kagura, an incubus that has been feeding on the female students at Miko’s school. She manages to seal him, but in the process turns him into a chibi, lower powered version of himself. Miko initially tries to keep him secret from her family, but they inevitably discover Kagura but allow him to remain with Miko due to his small size. Meanwhile Kagura has shown the ability to enter Miko’s mind while she’s sleeping, where he is able to assume his full size. Kagura uses this as an opportunity to attempt to seduce Miko, with some success.
