Starting the Holy Grail War with the Shadow Legion

“Fuyuki City sure has changed with the times.” After transmigrating back to Japan in the 1990s, Roland realizes he's in serious trouble the moment he hears people chatting and discovers that he's in Fuyuki City. But what's with all these annoying people? A certain shadowy general: “Give yourself to the ultimate darkness, and let truth embrace you!” A certain scumbag boss: “My other half, the farther you go, the more you should understand that humanity has its limits...” A certain masked man: “There has never been any such thing as love and peace! You must create a perfect world!” “Damn it, stay away from me! I really don't want to be a villain!” This is the story of an innocent young man who eventually takes the path of a great villain and keeps going.
