A fanfiction of Re:Zero. Subaru was destined to be summoned, but he never appeared. Instead he was replaced with Leo Borealis, a man who once terrorized the world in his time. Now, however, Leo has been reset to his younger self, and with part of his memories eaten by Lye Batenkaitos, he now finds himself in an unfamiliar world with only scattered recollection of who he was.
