“Where… am I?” One day, I—a plain, average office worker and hardcore otaku—woke up in an unfamiliar room. Even my previously out-of-shape body had drastically changed. Thinking it must be a dream, I tried pinching my cheek… but it hurt like hell. Panicking, I checked the mirror—and there it was: “I-I turned into Jugram!?” Standing before me was the strongest final boss of the immensely popular fantasy novel “Holy Hero Iris”—the ruthless villain Jugram, who is fated to be slain by the heroine, Iris. To escape that doomed future, I decide to defect to the kingdom where Iris lives and aim for a peaceful, carefree slow life. But because my actions deviate from the original storyline, trouble keeps coming at me nonstop—!? Thus begins a chaotic romantic comedy packed with lovey-dovey antics and overpowered cheat abilities, starring a “does-it-when-he-has-to” final boss and a cute yet slightly muscle-brained heroine!
