Hikari

Hikari (光) is a young girl who is related to the Miyanaga family and she is a sickly girl who has to be moved around by a wheelchair.

Appearance
Hikari is a girl with chest-length blonde hair that a tuft sticking out from the side of her head where it is similar to Saki Miyanaga and Teru Miyanaga and purple eyes.

Final Eight Arc
Hikari is first shown in a flashback-like sequence when Saki is about to enter the tournament hall to watch Teru Miyanaga play. The girl itself is shown on a pier with Saki Miyanaga and in a photo with Saki, Teru and some adults. Other pictures in the sequence contain a hospital stretcher, an IV bag, a burning building, a burning wheelchair, and flowers. Later Saki dreams about the pier event with her. The girl is lying down and looking at fish, pointing them out to Saki. She's saying that they are fun to watch and yummy to eat. She then says that she loved to swim but, probably will never be able to again, so she'll watch the fish swim for her. She also tells Saki that she dreams of building an aquarium and that when its done, Saki and Teru should come and visit it where her wheelchair is shown.

Conclusions and Speculation
Memories of the girl seem very traumatic to Saki Miyanaga where the girl appears has had at least two tragic incidents: first one leading to the loss of her swimming ability and the use of a wheelchair, then one with fire. Where the apparent hospitalization happened is not clear (it's a popular theory that the burning building is a hospital, but this is not confirmed). The final incident is very likely to be a major cause of the rift between Saki and Teru Miyanaga.
