Vocaloid Tako Luka is portrayed in a dynamic, stage-ready pose that blends idol energy with underwater whimsy. The figure features long hair tinted with soft pink and teal highlights that cascade around her shoulders, and a pair of stylized octopus tentacles entwine around her arms and waist in a playful, protective embrace. Her outfit fuses futuristic idol styling with marine motifs: a glossy, form-fitting bodice, a multi-layer skirt with translucent accents, and sculpted fins that appear to ripple with every angle of light. The base evokes a coral reef, complete with bubbles and starfish, while subtle color gradients and crisp shading emphasize depth and movement. Attention to detail in the sculpt makes the character feel poised to sing at any moment.

In the Tako Luka storyline, she is a wanderer who bridges two worlds: the concert hall's bright lights and the ocean's quiet depths. She draws energy from fans who chant and clap, transforming that momentum into bioluminescent glow that pulses along her tentacles and hair. Her weapon is a microphone that doubles as a charm, awakening sea creatures and guiding currents during performances. With a curious spirit, she collects sea-glass tokens from each show, weaving memories into her costume. The figure captures a moment when she pauses mid-song to listen to the crowd, her tentacles curling in time with the melody, embodying the harmony of technology, art, and nature that defines the Tako Luka persona.
