Age: 10
Info: Aiko is the daughter of Kumiko and Kiyoshi. She's a perfectly healthy child except for the fact that she's mute. The first time she met the other scouts, she was eight; she met Hotaru's daughter, Jirian. Jirian is the one who led Aiko to the old woman who gave her her scout powers. Aiko first becomes Sailor Snow Sprite when she is 10. Aiko eventually kills Jirian. At her mother's death, Aiko and Kiyoshi moved from the Arctic to Neo-Crystal Tokyo where Aiko and the Sailor Sprites take the place of the original scouts and she is given the title of Ingurido (Hero's daughter) for her mother's sacrifice.
