Maachi Hisakawa is the Gokujou Seitokai's accommodation "Landlord" and overseer. Being only in the fifth grade, she does not attend Miyagami Academy classes. She is only of 11 years of age. Her duties at the Miyagami Academy are to cook, clean, and do such things a landlord would do. Maachi Hisakawa is proud of what she does, as it's fun and enjoyable to do what she does. In the show, she is almost always seen with a smile on her face and says little more than her trademark giggle, "tee-heh." Being that way, she is liked and cared for by the rest of the council.
