I'm Cosplaying an Anime Character in Another World

Sometimes, I'm "Hoshiguma," a traveler from another world; sometimes, I'm "Saint Lord," an ambassador representing another world; and sometimes, I'm just an ordinary high school student, studying diligently and known as the "Electric Shock Master." Reborn into a parallel world, I originally wanted to be a plagiarist, but this world is too dangerous, so I can only survive by using cheat codes and pretending to be other characters.
