Hendrik Van Zen is a poor chimney sweeper with a strange power: when drunk, he quite literally forgets his problems. One night's misadventure however nets him the loyalty and adoration of a younger and spirited lad.

Under the watchful eyes of the delinquent legends he's managed to enrage, Hendrik must deal with his screw-ups and learn to be the best tutor for the (not so young!) Gin as his big brother figure, in this delinquent steampunk-themed manga.
