The Black Witch's Sports Day (Part 2)
Come Sports Day, after Gyubid casts an unknown spell on her, Chiyoko spots Angolmois speaking to another man, Count Leonare, about the purposed ritual, learning the truth that perfoming the ritual will not help Suzuka's brother. Before Chiyoko can warn Suzuka, Angolmois uses paralyzing magic to prevent her from interfering with the ritual which Suzuka begins to perform atop a human pyramid. However, the ritual fails as Suzuka's magic had mysteriously disappeared. As Suzuka's brother's operations goes smoothly, Chiyoko learns from Touka that Gyubid had used a forbidden magic to sever Suzuka's pact with Angolmois, the punishment of which is becoming trapped in a tree in the Spirit World.

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.
