Elrena

Elrena is a character from Daybreak Town in Kingdom Hearts Union χ.

Before Kingdom Hearts Union χ
Sometime prior to the Keyblade War, Elrena was chosen by the Keyblade and likely joined one of the five Unions operating in Daybreak Town. Eventually, her aversion to darkness and exceptional abilities attracted the attention of Ava, who extended to Elrena an invitation to join the Dandelions. Elrena then trained under Ava in preparation to venture to the world outside, a world of dreams, and avoid taking part in the Keyblade War alongside the other Dandelions.

When the time came, Elrena left the old world behind and journeyed to the new world, subsequently forgetting everything about the world she'd left behind. Elrena would then relive her past experiences alongside the Dandelions, although unaware of the tragedy of the Keyblade War.

Kingdom Hearts Union χ
In realizing that his younger sister, Strelitzia, is meant to be among the Dandelions, Lauriam begins searching for her, looking towards the data of the Dandelions recorded from their experiences in the data worlds. Without answers, Lauriam approaches Elrena, intent on asking her about his sister.
