This is a tale of Lireis Deldearue, the sole heir to the demonic House Deldearue. Unworthy as a newborn, Lireis is sentenced to death. Will she survive? Maybe. Is it because she made a pact with the Demon King or that she was saved by Agnos, leader of the rival House Ardelos? Or maybe it’s because I reincarnated as Lireis, and I know what’s fated to come! I’m destined to resurrect the Demon King, continuing the eternal battle between monsters and humans, but what happens if I fight against fate?
