What if there was a manga named Harriet Potter about a teen sorceress who got into magical imbroglios with her studious friend Hermes* and lovably incompetent gal pal Rhonda?
Then it would look not unlike Maaria Laurinen's Rule 63 take — "For every given male character, there is a female version of that character. For every given female character, there is a male version of that character." — on J.K. Rowling's coming-of-mage tale. Behold the Valentine's Day romance between Luno and Nevillette and the eldritch gaze of She-Who-Must-Not-Be-Named, Valeriemort.
*Save Harriet Potter, all of the characters' names were unofficially and half-assedly promulgated by yours truly.
