Description
Lean, the long-time leader of Mismede's Fairy Tribe, possesses an age estimated between 612 and 614 years. Her physical development ceased in early adolescence, resulting in a petite stature resembling a young teenage girl. She is characterized by silver hair styled in twin tails, golden eyes, and mostly diminished fairy wings permitting only minimal floating capability. Her typical attire features Mercury's astrological symbol, consistent with her thematic elements.

Initially serving as Mismede's ambassador to Belfast, she later transitioned to the same role for the newly established Brunhild Dukedom. Her personality blends a playful, mischievous streak—often teasing others or causing minor troubles—with deep inquisitiveness regarding ancient artifacts like Babylon's flying structures. Early depictions noted notorious tendencies toward spiteful actions and overt perverse behavior, including inappropriately touching others while invisible and falsely accusing allies. These traits significantly tempered after her engagement and integration into Brunhild's royal structure, adopting a more measured and responsible demeanor. Her extensive lifespan fosters a calmer approach to relationships than younger characters, though she occasionally displays self-consciousness regarding the age gap with her fiancé.

A magic specialist, she commands six of the seven primary elemental magics (excluding darkness) and multiple null-type spells: 【Program】, 【Transfer】, 【Protection】, and 【Discovery】. She maintained the 【Program】 spell on her sentient bear plushie, Paula, for over two centuries. Post-engagement, she acquired the "Appraisal Eye" ability, enhancing her evaluation of magical items. In combat, she pilots the blitzkrieg assault-type Frame Gear "Grimgerde" to combat crystalline Phrase entities. This unit collaborates with other Frame Gears to operate the massive magical cannon "Brionac." After receiving a sacred ring from the World God, she channels divine powers for her fiancé.

Key relationships include becoming the eighth fiancée of Brunhild's ruler, evolving from professional respect and curiosity into genuine affection. She mentors Charlotte, Belfast's royal court mage, and relinquished her tribal leadership to Ellis upon engagement. Subsequently retiring as ambassador, she assumed the position of Brunhild's court magician. Personally, she bears a daughter and expresses concern that the child's extended lifespan, inherited from divinity, will surpass her siblings and relatives.
