If he kisses someone, his magic will disappear... but he's gone for years without knowing the touch of another's lips, and so remains a (crusty and old) magic warrior! In a sexy(?) tentacle battle against the evil General Onyx, his wardrobe malfunctions, revealing his true form to his archnemesis!! In this volume, anything goes as our hero battles every day in the name of justice!! (Source: Renta!)
