Hendrik Van Zen is a poor chimney sweeper with a strange power: when drunk, he quite literally forgets his problems, turning into a cool, witty version of himself without his tumultuous memories. One night's drunken mishap nets him the loyalty and adoration of Gin, a younger and perky boy whose loyalty knows no bounds.

Under the watchful eyes of the delinquent legends he's managed to enrage, Hendrik must deal with his often wine-flavored demons and learn to be the best tutor for the (not so young!) boy eager to learn from his newfound "big bro", in this delinquent steampunk-themed manga.
