Strange Confectionery Contest (Part 1)
As a cake contest is held, Gyubid teaches Chiyoko a duplication spell to make a copy of herself to look for rare chestnuts for a mont blanc. Things soon get awkward as the copies start making copies of themselves that deviate further from the original with each duplication, so Gyubid and Chiyoko set off to capture all the copies.

Kuromajo-san ga Tooru!!
Kurotori Chiyoko, a 5th-grader in elementary school, loves the occult. One day, a friend requests her to do a love fortune-telling. Chiyoko tries to summon Cupid, but thanks to a stuffy nose, accidentally summons a witch named Gyubid instead!
From that day on, Chiyoko starts learning witchcraft from Gyubid, the self-proclaimed hottest instructor of the magic world. The training regimen is tough, and punishment for slacking is harsh. Fortunately, Chiyoko is able to keep her extra-curricular studies secret, aided by the fact that no one else can see Gyubid.
