Akuyaku Reijou, Juukai Shindara Nanka Kowareta.

Having been betrayed and killed so many times, she thought that encounters and partings no longer mattered at all..!? Fiora, a 17-year-old known as the "Witch of Purgatory" and feared by the people (except for Saint Mesera), thought this life would be the same as always.. and set out alone to defeat the Demon King, only to meet him!! Demon King Repetera!!! Yes, I've decided. In this life, I will spend my life with this beautiful boy!
