I'm not gonna lie this is incredibly tedious with the chapters being broken up as they are, especially since every chapter just reiterates that she has lived multiple horrible lives.
The title reminded me of "The Villainess Wants to Enjoy a Carefree Married Life in a Former Enemy Country in Her Seventh Loop!" for a second. This is not that.
after experienced multiple loops of horribly pain and suffering, she began to possessed a quite strong sense of self plus her power alone is already that cracked
similar to "7th loop villainess" but with colder personality and magic ability.
