Watashi ga Akuyaku Koushaku wo Tasukeru Riyuu

Belona Rosentine, a woman sick and tired of dying and reincarnating over and over no matter what choice she makes. To break free from the cycle of reincarnation repeated over twenty times, she decides to make a choice she never once made in her previous lives.

To help the dark mage ‘Demonic’, the original ‘villain’, find redemption. Contrary to her expectations that stopping his future rampage as a dark mage might change something, Demonic and several other men show interest in her. For the first time in this life, Belona falls in love with Demonic. She finally finds the ‘hourglass’ that could break the cycle of rebirth, but her life only spirals further out of control.
