Once upon a time, there was a witch named Ireina. In this continuation, the girls connected to her will reappear. The girl who can see the future and the false witch with great fortune, the close-knit sisters who have been drifting apart lately, the duo of schoolgirls who continue their historical explorations, the girl skilled in potion-making and the eloquent correspondent of a certain age, the beautiful woman who understands the language of things known as the "Coal Witch," and the heartbroken "Witch of Incense" and "Witch of Charcoal"... The girls whose lives were dramatically changed by their encounter with the Ash Witch will weave a new story as they sometimes fight and sometimes support each other. "I hope you won't underestimate the traveling witches too much."
