LEVEL 1 DEMON LORD AND ONE ROOM HERO VOL 1 TPB

An odd-couple comedy about a has-been hero and the Demon Lord trying to whip him into shape! Ten years ago, the hero Max defeated the Demon Lord. In order to regain his power, the Demon Lord went into a deep slumber... but when he awakens, his body is only a chibi version of its fearsome form. Now curious to see what his enemy is up to, the Demon Lord visits Max, only to discover the mighty hero living in a dirty one-room apartment. The Demon Lord decides to move in with Max and help his old enemy become a formidable opponent once more!
