The class representative witch. Her nature is to remain an onlooker. Using the spiderlike threads which she vomits forth, she created a school for herself alone within the sky of her barrier and endlessly acts out an ordinary daily student life there. If you ring the going-home bell, this witch will likely return to her house somewhere.
The class representative witch's minions. Their role is to be her classmates. Although the skates on their feet allow them to glide gracefully along the threads, all of them are actually controlled by the witch using her threads, and they have no will of their own.
