I’m No Hero in the Shadows!

Overview

The Hero in the Shadows—a mysterious savior who appears and disappears out of nowhere to rescue those in need. To the world, his identity is an enigma… or at least it WAS, until the entire town discovers it’s none other than Phil Salembart, the lazy, womanizing son of a count! Now stuck with the embarrassing truth out in the open, Phil scrambles to deny it—while women indebted to his hero alter ego keep flocking his way: a saint, a noble’s daughter, even the kingdom’s princess?! A fantasy comedy that starts AFTER the big reveal—because this Hero didn't stay in the shadows for long! (Source: Manga UP!)
