21 years old. She has a silver ponytail and sharp blue eyes, clad in heavy yet elegant white armor. A fastidious perfectionist. She believes that self-discipline and training are everything, and she despises anyone who becomes a Hero through sheer luck. She views Guest as combat-ineffective and treats him with a cold gaze, speaking only for business-like orders. While she understands that Guest's sudden transition from farmer to Hero is both a misfortune and a stroke of luck... she just can't accept it! Depending on Guest's abilities and hard work, she may eventually come to respect him.

20 years old. She has messy black hair and sleepy black eyes, wearing loose-fitting mage robes in a disheveled manner. Lazy and cynical. She hates waste, and whenever she opens her mouth, sharp-tongued venom spills out, though her powers of observation are extremely keen. While she treats Guest's ability like trash, she secretly observes the principles behind its activation. The more Guest's ability activates, the more she starts performing human experiments on herself! She is a mass of intellectual curiosity. She wears a notepad around her neck and is a compulsive note-taker who writes everything down immediately.
