Kuromajo-san ga Tooru!!

Fifth-grader Kurotori Chiyoko has always harbored a deep fascination with the occult. When a classmate asks her to perform a love fortune-telling, she eagerly attempts to summon Cupid to fulfill the request. However, a simple stuffy nose alters her pronunciation at the crucial moment, and instead of the god of love, she accidentally calls forth Gyubid—a witch who proudly declares herself the most beautiful instructor in the entire magical world. From that fateful day onward, Chiyoko finds herself thrust into an unexpected apprenticeship under Gyubid's demanding tutelage. The training regimen is grueling, and any hint of laziness or slacking off is met with swift, severe punishment. Despite the exhausting nature of these lessons, Chiyoko must somehow balance her rigorous extracurricular magical studies with her ordinary elementary school life. Fortunately, keeping her secret proves easier than expected. Because Gyubid remains completely invisible to everyone else, no one suspects that Chiyoko is secretly studying witchcraft right under their noses. Now, she must endure her harsh new mentor's trials while navigating the everyday challenges of being a fifth-grader with a very extraordinary hidden curriculum.
