The Demon Lords are powerful beings that create and control monsters and demons. They construct malevolent labyrinths and select individuals who possess exceptional abilities as their vessels. These Demon Lords entice people to visit the labyrinth they've built, consuming their despair as sustenance. However, a newborn Demon Lord named Procell has chosen to obtain hope instead of despair from humans as nourishment. He plans to construct a joyful town rather than an evil labyrinth. This narrative follows the unique journey and challenges faced by this unconventional Demon Lord.
