Hakushon Daimaou, named Bob in most dubs, is the genie who resides in the bottle Kan-chan found. Whenever someone sneezes he is brought out and has to grant any wish of whoever sneezed until he or she sneezes again. He is somewhat clumsy though, so sometimes he accidentally fails and causes trouble instead of granting any wishes. He's not very good at math either.

He has a daughter named Akubi who also lives inside the bottle.
