Yuumi stands on a translucent base, mid-leap with her paws tucked under her chest and her tail curling behind her. The Heartseeker Pearl Chroma palette bathes her fur in a pearly white with soft pink accents along the ears, paws, and chest, while a pink heart motif adds a touch of romance to the design. Her eyes are large and glossy, catching light to give her a lively, anime-inspired look. The floating Book of Tells accompanies her, its spine etched with gold runes and a gentle pink glow that hints at magical energy. Her fur sculpting reveals delicate tufts and subtle shading along the coat, and the accessory pieces are finished with clean lines to emphasize finesse. The overall presentation aims for a bright, charming presence that complements the Heartseeker theme without overwhelming the character's playful silhouette.

Yuumi is a magical cat from Runeterra whose stories revolve around companionship and aid. Bound to a living book, she travels with allies rather than leading the charge, projecting her supportive magic to shield and heal while remaining near her chosen comrade. Her charm lies in the way she attaches to friendly champions, sharing her resources and turning battles into cooperative games. In the Heartseeker Pearl Chroma skin, her romance-inspired aesthetic reflects the series’ seasonal themes, yet her core identity as a loyal, curious mentor remains clear. This figure captures that duality: a soft, affectionate presence embodied by the pearly white hues and hearts, and a nimble, mischievous spirit ready to leap into action beside a sworn partner. It celebrates Yuumi’s role as a friendly guide who values connection, empathy, and teamwork.
