- "Inside me is a list of all the important requests everyone has made. Because let's face it, everyone needs help sometimes. But you can't solve all of them at once. No, no! So I'll help you solve them one by one. You got that?"
- ―Eliza, Rune Factory 4.
They are the Request Box located in Selphia's Town Square. It is made apparent that only Lest, Frey, and Pico can hear their voice, although it is unknown if this ability is exclusive to Earthmates. They imply to the protagonist that the reason they can speak must have been that they were made using materials from the Sharance Tree, indicating that the tree possesses enough earth power to animate them into existence. The player can decide whether Eliza is male or female, as they ask the player after a certain amount of quests have been completed.
Eliza was made from a large tree, suggested to be the Sharance Tree.
- Eliza's Japanese name, Iraiza, is likely a pun on the word "irai," meaning request.
