Kairo Packer is an average nineteen-year-old man who earns coin working shifts at a convenience store. You'd think with a name like "Kairo" he would've faced some hand-warming conversations or combative situations in his life. Nope. Safe from street dangers. Overlooked by woman. Even bypassed by street cats. Not one goddamn cat hiss.

One day, his passion for weird items has him buying a mysterious-looking Baroque closet and lamp from an online store. Little did he know that fully installing this furniture in his room would (literally) open a door to a new world and life—especially when he finds himself as the Demon Prince's new House Wizard with the Power of Mundane.

Zapped from a safe and comfy life in suburbia: now facing a new reality of deviousness and danger in a fantasy world. Can this new fodder wizard survive? Especially when he could easily be a splatter stain on the floor the next day.
