Blue Morris Rui Elmitage is both lady-in-waiting and close protector to Princess Minerva, serving within her personal guard unit. Her duties encompass the princess's direct security and participating in missions against threats to the kingdom.

At a tournament where Princess Minerva aimed to win a substantial fortune, Blue Morris enacted a deception, disguising herself as the princess to allow Minerva to compete incognito. This ruse led Dynastar's agents to mistakenly identify Blue Morris as their target. Consequently, she was gagged, bound, and abducted inside a sack intended for Minerva. Held hostage, Blue Morris became leverage to compel Minerva's compliance.

Before these events, Blue Morris had counseled Minerva against directly confronting the sorceress Dynastar. Her abduction inadvertently removed the primary voice urging restraint from the princess's circle.
