Marnie

Marnie is the titular character of the film When Marnie Was There. It is revealed that she is actually Anna's biological grandmother (specifically the mother of Anna's biological mother).

Biography
Marnie was raised in the Marsh House when she was growing up in a seaside town. She was often mistreated by the maids while her parents were out. Eventually, she met a man named Kazuhiko. Kazuhiko and Marnie spent a lot of time together, often sneaking out. One day, Kazuhiko and Marnie went to the silo that Marnie was deeply afraid of, due to the maids' usage of the location to secretly abuse her. She nearly died while in the silo, before Kazuhiko saved her.

After Marnie grew up, she married her childhood sweetheart, Kazuhiko and had one child, a daughter named Emily. While Emily was still a young child, Kazuhiko died of an unknown illness. The shock of his sudden death caused Marnie to fall ill, and subsequently resulted in her having to be institutionalized in a sanitarium for some time. Marnie's parents had since passed away, and Kazuhiko's family was never mentioned, thus, Emily was sent away to boarding school. Years later, Emily (said to be 13 at the time) returned to her mother's care, but had strong feelings of anger towards her due to her perceived abandonment.

Marnie and Emily's relationship was never salvaged and when Emily was a young adult, presumably in her late-teens or early-twenties, Emily ran away from home after having once last argument with her mother to marry the man who had gotten her pregnant. Marnie was not informed of her daughter's marriage of the birth of her grandchild, Anna. When Anna was two years old, Emily and her husband were killed in a car accident. Marnie took Anna in and did her best to care for her and make sure her granddaughter could never feel alone but she never recovered from Emily's death. Unfortunately, Marnie fell ill and passed away when Anna was still a toddler. Anna was then placed in foster care, where she was taken on and possibly adopted by Yoriko and her husband at the age of five.

After Marnie's passing, her spirit returned to her hometown, mainly to her childhood home and the abandoned silo. The townsfolk eventually noticed her presence and avoided said places.

When Anna was forced to go to the seaside town that Marnie grew up in, she re-lives some of Marnie's memories with Marnie herself (who made herself look like her preteen self) taking the place of Kazuhiko in (most) of the memories and their time together helped Anna to become less introverted and more willing to open up to people.
