0/6 (Zero/Six) is a Korean manhwa series written and illustrated by You-Jung Lee, serialized in 2006. The story follows Moolchi, a shy, unassuming boy whose life is turned upside down when his absentee father sends him a stunningly-proportioned automaton named "Six." Six claims to have a "prime directive" and begins to violently dispose of anyone who gets in her way. Meanwhile, Moolchi remains blissfully unaware of the cute hall monitor who harbors a crush on him or the intentions of this mysterious femme fatale.
