Karasu from Hololive in the La+ Darknesss portrayal is rendered as a striking 1/7 scale figure. The character stands in a poised, dynamic pose, one foot resting on a stylized stone pedestal that suggests a moonlit stage. Her attire blends gothic elegance with feathered accents: a flowing black cloak trimmed with iridescent feathers, a high-collared bodice, lace sleeves, and layered skirts that cascade in wind-swept folds. Subtle crimson ribbons weave through the outfit, and metallic buckles and jewelry catch the light. Her hair is sculpted in glossy dark locks that frame a piercing gaze, with crow-themed headpieces completing the silhouette. The base features carved talons and a wind motif, enhancing the dramatic presence and sense of motion.

In Hololive's broader lore, Karasu, channeling the La+ Darknesss persona, is a mysterious guide of nocturnal stages. Born from a whispered legend of a crow spirit who thrives where lantern light wanes, she moves unseen between fans and fates. This figure embodies that dual nature: elegant, aloof, yet playful when the moment calls for mischief. On stage she casts shadows that seem to bend to her will, while off stage she guards hallways of memory, collecting moments of fans' cheers like gleaming talismans. Her La+ Darknesss identity hints at a darker, more enigmatic persona that surfaces during special events, inviting collectors to explore the boundary between performance and myth, while celebrating the connection between character and audience.
