Demon Love Spell Vol. 1 (manga)
Miko is a shrine maiden who has never had much success at seeing or banishing spirits. Then she meets Kagura, a sexy demon who feeds off women’s feelings of passion and love. Kagura’s insatiable appetite has left many girls at school brokenhearted, so Miko casts a spell to seal his powers. Surprisingly the spell works—sort of—but now Kagura is after her!
