Majo to Kyurasu

Long ago, the talented witch Shien helped her apprentice Tama escape from the witch hunts and then disappeared. Hundreds of years later, the two finally reunite in modern-day Japan! However, there is no trace of Shien's former self. She is now a "downer witch" smoking cigarettes by the window...! A decadent comedy about the everyday lives of the diligent Tama and the lethargic Shien!
