筒井康隆
is a 2006 Japanese-animated science fiction romance film produced by Madhouse, directed by Mamoru Hosoda and written by Satoko Okudera. Released by Kadokawa Herald Pictures, the film is a loose sequel to the 1967 novel of the same name by Yasutaka Tsutsui and shares the basic premise of a young girl who gains the power of time travel and repeatedly relives the same day in a time loop, but with a different story and characters than the novel. Riisa Naka voices teenager Makoto Konno, who learns from Kazuko Yoshiyama, Makoto's aunt and the protagonist to the original story, that Makoto has the power to travel through time. Makoto begins using the time-leaps frivolously to fix problems.
