Lady Noia is a childhood friend of Prince Lumen's. She is impersonated by Beerain in order to sneak into Arachna Castle and steal the Oracle Keys from Hunter. The attempt was thwarted several times because Lumen, who had fallen in love with Noia, was always going to check up on her, giving her no time to sneak away. After Beerain discards her disguise, Lumen continues to pursue her and misses the arrival of the real Lady Noia.
