Highschool boy reincarnated as duchess in fantasy world.

“In a world ruled by elements, history has forgotten the one who created them.”



A high school boy dies and is reincarnated as a noble woman—now a young professor at the most prestigious academy. While teaching prodigies and guiding future warriors, she hides a power long erased from the history books.



Unknown to the world, she’s the vessel of an ancient, omnipotent element—one that predates the gods and once shaped the very laws of magic. As cults rise, demons hunt, and divine beings scheme, she must survive in a world soaked in blood, uncover a forgotten past, and protect the students who trust her.



But this isn’t her fight alone—it’s the reckoning of a world built on lies.



What if the one who created the elements was never meant to return… but did?
