One day, Kan-chan found a ladder to the attic in a closet. When he climbed to the attic, there were various junks. He stumbled over an old clock, raised the dust, and it made him sneeze. Then, a strange jar dropped from the ceiling, and a man came out of the jar. It was Hakushon Daimaou. He was supposed to grant all the wishes of the person who get him out of the jar by sneezing until he sneezes again. However, he always failed and made troubles.
