Rurumo

The protagonist of this work. A witch who made a contract with Shibaki in the first part (in the first part, she was stripped of her witch qualifications, so she is an apprentice witch). Her real name is "Maji Mojiruka Rurumo." She appears to be an ordinary middle school student, but her actual age is 315 years old. She is afraid of frogs. She can use magic to grant the wishes of her contractor. She is extremely expressionless and quiet, but this is due to her being extremely shy. She was once deceived by other witches, broke the rules, and was imprisoned for 60 years. She is clumsy and struggles with riding a broomstick. In the human world, she works as an apprentice in the cafeteria of Shibaki's high school, but she is very clumsy and often makes mistakes. She finds joy in life on the surface and often reminds herself, "I am getting carried away." Her job as an apprentice in the cafeteria was also a result of this, and she takes on other part-time jobs during summer vacation. Originally, she was a thirteenth-class witch, the lowest rank, but she has high magical abilities despite her lack of ambition. She feels gratitude towards Shibaki, and special feelings begin to develop between them. Due to her shyness, she often struggles to express her gratitude properly.

In the third part, she is promoted to a second-class witch and supports Lucika and others as a "Special District Inspector for the Ground Witch Management Section of the Demon World Management Bureau." She also infiltrates Lucika's middle school as a chemistry teacher. Her name on the surface is "Majima Moji Rurumo."
