Mizukura Risuka, also known as "The Red Witch of Time," is a fifth grader in the Saga Prefecture. At the start of the story, she has been magic hunting for two years, and has worked with classmate Kizutaka Kugi for a year. While she is listed on the elementary school register, she rarely attends, preferring to stay at home transcribing magic tomes and watching sumo wrestling. Born and raised in Moriyashiki City in Nagasaki Prefecture, Risuka but did not learn Japanese until she moved to Saga to search for her father, Shingo. Kizutaka calls her speech "like badly translated German" because she reverses the subject and predicate; for instance, she says, "Not kind to me, that Kizutaka is." Risuka's magic classification is: Element: Water, Type: Time, and Manifestation: Moment. Most of her magic abilities involve shedding her blood and borrowing time. For example, she can appear to heal or move to a place instantly by fast-forwarding her life. When she loses a large amount of blood, she can, for one minute, become 27 years old, which is her prime fighting and magic casting condition, and is very aggressive.
