Ingrid Sorveig Sorgríms, nicknamed "Ini" by Asuha Tohara, is the seven-year-old Great Sage of Álfheimr, inheriting her title and immense intellect from her 300-year-old father, Sorveig Otto Sorgríms. Anticipating his death, he transferred three centuries of accumulated wisdom into her mind via a specialized ritual, embedding his legacy within her.

Ini’s striking appearance features long light-purple hair tied in bunches, crimson eyes, and a petite frame of 99 cm and 15 kg. She dons a red swimsuit-like garment layered under an oversized blouse—colored dark purple in anime adaptations and black in the manga—accented by a red ribbon and matching shoes.

Raised in seclusion within her father’s ivory tower, Ini’s solitary life shifted upon meeting Naoya Tohara and Asuha, whose encouragement led her to move her tower to Astarotte Ygvar’s estate, embracing newfound social connections. Though intellectually advanced, her limited worldly experience surfaces as earnest curiosity and moments of childlike naivety, tempered by a composed disposition and occasional whimsy.

Asuha remains central to her emotional growth, not only coining her nickname but also guiding her into understanding affection and friendship. Ini’s bond with Naoya deepens into romantic attraction, culminating in an anime kiss and a manga declaration of love, which strains her ties with others.

Her expertise lies in wielding vast scholarly knowledge and potent magic to aid allies, though she avoids physical exertion like swimming and recoils from spicy foods—traces of her sheltered past. Across her journey, Ini evolves from isolated prodigy to an engaged participant in communal life, motivated by deepening relationships and a thirst to explore existence beyond academia.
