Description
Yotsuha Miyamizu is the energetic nine-year-old younger sister of Mitsuha Miyamizu, living in Itomori during 2013 with Mitsuha and their grandmother, Hitoha Miyamizu. Born July 2, 2004, she has few memories of her mother, Futaba Miyamizu, who died when Yotsuha was about three. Her father, Toshiki Miyamizu, lives apart pursuing politics, but Yotsuha lacks the complicated feelings toward him that Mitsuha harbors. As a Miyamizu family member, she upholds traditions as a shrine maiden, participating in Shinto rituals like making kuchikamizake and braiding cords, though she sometimes finds these duties tiring.
Level-headed, observant, and responsible beyond her years, Yotsuha routinely wakes Mitsuha and helps with household chores. She is perceptive about behavioral changes, frequently noticing and commenting on Mitsuha's unusual actions during body-swapping incidents, which she teasingly attributes to strangeness or madness. Despite her maturity in daily tasks, she acknowledges her limited worldview as an elementary schooler and actively seeks to learn more. A mischievous or entrepreneurial streak occasionally surfaces, like suggesting selling ceremonial sake for profit—an idea Mitsuha quickly dismisses.
In the original timeline, Yotsuha perishes with Itomori during the comet strike on the autumn festival day. However, interventions by Taki and Mitsuha alter events, evacuating the town and ensuring her survival. Relocating to Tokyo with her family, Yotsuha appears as a 17-18-year-old high school student in 2021–2022, wearing a standard uniform with longer hair styled in twin tails secured by blue hairbands. She retains her spirited demeanor; a manga scene shows her threatening to arrange marriage interviews for Mitsuha if she neglects visiting home. She also briefly appears reacting to sunny weather in Tokyo during August 2021.
Her surname, Miyamizu (宮水), meaning "shrine water," reflects her family's shrine heritage, while her given name, Yotsuha (四葉) or "four leaves," continues the naming pattern shared with grandmother Hitoha ("one leaf"), mother Futaba ("two leaves"), and sister Mitsuha ("three leaves"). Her speech is peppered with the regional "-ya" suffix. Later life circumstances are unspecified, though she likely resides in Tokyo with her father and/or grandmother while Mitsuha lives independently.
