Reborn as the Demon King of Soul Town

Cast out from the magic world for creating the tenth forbidden spell, he becomes something far greater—a Demon King who bridges worlds and commands the spirits of the dead. In a reality where humans and souls coexist, he walks the path between magic and spirit power, guiding lost beings through Soul Towns while unraveling the mysteries of the Holy Grail War. An outcast turned sovereign, a traveler who rewrites the rules of existence itself. His journey home will shake the foundations of multiple worlds.
