Once upon a time, there was a witch named Ireina. Unusually, she is enjoying a leisurely journey with her mentor, Fran. This time, she encounters a variety of characters: a captain and a record keeper living in a mysterious diner, two female students dedicated to historical exploration, a charcoal witch and her talented assistant, a girl infatuated with a prince and her bewildered family, as well as a girl from a prestigious family of magicians and her orphan friend. What kind of salvation will the encounter with the witch bring to them? "Sensei, let's definitely accomplish this request!" This is the tale of the two witches of "Ash" and "Stardust," their journey, and a story of "parting" that creates the future.
