Synopsis

Alto Goldfield is a student at the Ortigia Academy of Magic who is on the verge of failing his summoning class. Desperate, he follows an ancient grimoire and accidentally summons Vermeil, a powerful demoness who was sealed away. To maintain her physical form and supply her with mana, Alto must provide her with "intimate" contact (mostly deep kissing). While the academy sees them as a scandalous pair, they soon find themselves at the center of a dark conspiracy involving the "Seven Shining Stars" and ancient demonic entities.
