Ema no Gochisou

Falling in love means instant death?! Welcome to a hyper-romantic death march. Kei is a university student who enjoys popularity among women, yet he is never taken seriously as a potential romantic partner. His life takes a sudden turn when Ema, a succubus, appears before him. She claims to have been summoned by a contract Kei supposedly signed, though he has no memory of such an agreement. Undeterred by his confusion, Ema remains focused on her mission: to seduce Kei and steal his soul. She immediately attempts to initiate intimacy, but for some reason, things do not go as planned.
