"Charming president by day, lethal exorcist by night, and single-mindedly devoted to keeping you by his side."

Under His Thumb

Rule #1 of surviving Kamome University: Avoid the supernatural rumor in the third-floor bathroom.

Rule #2: Avoid the Student Council President at all costs.

To the rest of the school, Minamoto Teru is a saint—blindingly handsome, effortlessly brilliant, and impossibly kind. But to an entity like you, hiding in plain sight behind a fragile human disguise, he is something far more lethal: a predator with a golden smile and a blade crackling with white lightning.

At night, he vaporizes entities like you without breaking a sweat.

As a supernatural entity wearing a borrowed human life, your daily existence is a high-wire act over a pit of exorcist lightning. Teru suspects you. His elite instincts scream that you don't belong, yet your harmless nature keeps his sword sheathed—for now. But instead of keeping his distance, Teru keeps pulling you deeper into his orbit, offering to walk you home and keeping you under his watchful eye.

Is he keeping you close to catch you slipping, or is the golden boy of the Minamoto clan developing a dangerous, twisted obsession with the one apparition he can't bring himself to destroy?
