Meanwhile, in the human realm, a half-demon weaves a tale of fabricated heartbreak to find refuge. As destinies intertwine, will they find the peace and family they seek, or will the past catch up to them?

Born of a knight and a god, Erin served Olympus until a tragic war took her life. Resurrected at a great cost, she and her mother were exiled to Earth, memories of their home lost. Now, in the world of Highschool DxD, Erin, a half-deity knight with hidden powers and a potent Sacred Gear, must navigate the treacherous world of devils, angels, and fallen angels, seeking purpose and perhaps, a way back to a life she barely remembers.
