Ria is a member of the High Elf race, her particular tribe being devastated by war, with males being "sent away" to other tribes, leaving her and other females forced to fend for themselves and at the risk of being treated poorly by other tribes.
She leads several others female High Elves throughout the world for many years. However, this changes when she befriends Tia, an Angel.
Needing help, as she doesn't want to toil at the newly formed farm alone, Tia brings the High Elves to Hiraku's farm located in the Forest of Death, secretly promising an unaware Hiraku as "breeding" stock to help repopulate the High Elf race.
Ria would later become the leader of the High Elves on the farm, which over time would turn into Taiju Village, as more of her fellow High Elves, as well as other races would join them.
