Kinsou no Vermeil

Kinsou no Vermeil unfolds at Ortigia Academy of Magic, where Alto Goldfilled, a diligent student on the brink of repeating a year, cannot seem to pass his summoning class. Desperate to avoid failure, he opens a battered grimoire and accidentally calls forth Vermeil, a powerful demon whose sudden appearance upends the careful routine of his school life. Vermeil does not fade away after the ritual. Instead, she chooses to remain at Alto's side as his familiar, sealing their pact with a deep kiss and tying their fates together in a bond neither of them fully understands. As Alto works to master the power he has awakened, Vermeil's mysterious past begins to surface, hinting at dangers and secrets that reach far beyond the academy walls. Between spellcasting lessons, clashes of personality, and increasingly intimate encounters, Kinsou no Vermeil follows their volatile partnership as it grows into a fragile trust in a world where every spell can shift the balance of power.
