Here Comes the Black Witch!!(2012)

Here Comes the Black Witch!! is an anime series following Kurotori Chiyoko, a fifth-grader obsessed with the occult. When a classmate asks her to perform a love fortune-telling, Chiyoko attempts to summon Cupid but botches the spell—a stuffy nose leads her to accidentally conjure Gyubid, a self-proclaimed master witch instead. From then on, Chiyoko begins learning witchcraft under Gyubid's demanding tutelage. The training is grueling, with harsh punishments for any sign of laziness. Chiyoko manages to keep her magical education hidden from everyone around her, since only she can see her invisible instructor. The series blends comedy with the clash between everyday school life and secret supernatural lessons.
