Koushaku Reijou wa Mou Yurusanai

Siesta, a duchess with the power to rewind time when she dies, is born into a noble family that ultimately betrays and shames her. Facing her tenth death, she realizes their love was merely emptiness, and resolves: “This will be the last time I shed tears for these people.”

In her eleventh life, armed with time-reversal, teleportation, and the ability to turn objects into butterflies, she sets out to enact revenge against those who hurt her. Once disregarded like a sacrificial pawn, Siesta uses her abilities and intellect to triumph with stunning elegance.
