Kasumi Mayu

The older of the twin sisters. She has a permanent poker face, so no one except for her sister can tell what she's thinking. Despite her expression, she loves playing around with Yuma, pranking people and re-enacting scenes from their favorite mahou shoujo anime Doricchu. She always wears a hat with cat ears and a tail, imitating Doricchu's looks.
Calls the protagonist "Anii".
