Although suffering from heart disease, the parents of the young Xiang (voiced by Shenmu Longzhijie) still neglected to care for him. In order to prepare for the upcoming surgery, Xiang came to the home of his aunt (voiced by Takeshita Keiko) in the remote countryside to recuperate. The aunt's house is located in a quiet jungle. This is a European-style villa with a history of hundreds of years. In addition to the aunt and the maid Chun (voiced by Shirin Kiki), there is also a peculiar family of three, the "borrowing family"-the villain Arrietty (voiced by Shida Mirai) and her father (voiced by Miura Tomokazu) and mother (voiced by Otake Shinobu), who live under the floor of the villa, only a few centimeters high, and live a life that is not noticed by humans. When you encounter the daily necessities you need, you will sneak into the kitchen to borrow them in the dead of night. Xiang accidentally glimpsed the figure of Arrietty. He was interested in approaching these legendary villains, but he unknowingly disturbed their lives... This film is adapted from the original work "The Borrower" by British writer Mary Norton, and won the 2011 Japan Academy Award for Best Animation.
