Published in 1997 in an issue of Weekly Shonen Jump for the "Jump Readers' Cup", this manga tells the story of two young demons named Bubul and Purupuru who venture outside of their village to the human world to make snowmen. During this activity, they hear an approaching car and quickly check it out which leads into hijnx. This manga won the award that year, marking the first time Toriyama won it since his 1981 one-shot "Pola & Roid" and its demon world notably has several concepts that would be reused in Cowa, one of his single-volume length tales.
