Sachiko is Satoru's mother and former news announcer. She possesses a sharp eye and is quick to observe any irregularities. She knows about the cold cases of serial kidnapping in her town but decided to keep quiet and ignore it for her child's growth and safety. However, after making eye contact with the criminal at his latest kidnapping attempt, she was killed by the kidnapper. This, in turn, triggered Satoru's "Revival" which sent him 18 years back in time. Originally, Satoru was supposed to prevent the serial killer from noticing Sachiko's presence in the parking lot, where the first Revival of the day occurred, to prevent her death. Sachiko is a middle-aged woman with pronounced lips and a slim figure with long hair in her youth, but has it in a bob cut in her later years. Satoru notes that she looks remarkably young for her age. Sachiko is a kind and caring woman and a devoted mother who goes to great lengths to care for her son. She's described as a strong and willful person, having dealt with various problems while striving for a better life. At times, she feels she doesn't fully understand Satoru, but never stops caring for him. Satoru refers to her as a demon due to her ability to read his thoughts, something he finds frightening though he deeply cares for her. She tends to keep things to herself in order not to worry others, especially her son. Sachiko's observant nature and instinctive ability to understand people and their motives combined with some decent detective sleuthing skills seem to come from her former job as a news anchor.
