A music video work created for the AI creative contest “Corotech supported by LIVE DAM WAO!” hosted by the Nippon Columbia Group (NCG) on February 21–22, 2026. Starting from my own sense of motion graphics, all motifs were individually generated by AI as video assets for chroma key use, then constructed through compositing and synthesis. Rather than generating everything at once, the video was structurally designed through a process of generating, selecting, placing, and animating each element as separate assets. Within the context of an AI contest, I deliberately chose a time-consuming production method in an effort to imbue the video with “brushstrokes” and “life” that cannot be achieved through one-shot generation. Rather than relying on AI’s generative power alone, this work explores the possibilities of expression through collaboration between AI and humans by selecting, composing, and assigning relationships to the materials through human intent. Instead of presenting AI’s inorganic output as is, it aims to create an emotionally resonant visual expression by reconstructing it through human intervention.

A music video created entirely in full CG. Built around the guitar as its central motif, the visual world was constructed from its form and presence. Assuming the piece to be instrumental, the visuals were designed not around the meaning of lyrics, but around the structure, texture, and energy of the sound itself. The dynamics, rhythm, and spatial breadth of the music are visualized through the deformation of forms, light, and motion. Through motion graphics design in Cinema 4D and Redshift, along with highly precise lighting and rendering, we created a full-CG expression in which sound and image are directly connected.

Based on the images inspired by the music, original hand-drawn illustrations were created for each scene and used to construct the music video. The movement within the video was built from those original drawings, incorporating AI technology while preserving the texture and nuances of the hand-drawn work as it was developed into moving images. In addition, these original drawings were compiled into a ZINE as part of the artist’s own body of work and exhibited at “Here is ZINE Tokyo #22,” held in Aoyama, Tokyo, in February 2026. Rather than stopping at completion as a video work, the project expands its world by translating the original drawings born during the production process into an analog medium, crossing the boundary between moving image and printed matter. Starting from the traces of hand drawing, this project developed into a distinctive artwork that moves back and forth between analog and digital through a process that unfolds from still images into time-based expression.

This is an original video work created inspired by Roniit’s song “Purify.” Using CG, I expressed the themes of “life that is born and then fades away” and “a world that is magnificent and beautiful, yet somehow tinged with fragility and irrationality.” A single star is born in a sterile space. The life that emerges from it encounters other forms of life, collides with them, undergoes chemical reactions, and eventually disappears— this entire process is depicted abstractly from the perspective of an unemotional third party. While centering on my strengths in 3DCG and VFX, I also experimentally incorporated AI technology at certain points, blending them together in a subtle way. I made this video with pure feelings as a fan of Roniit, and I was truly delighted to receive a message from Roniit through social media, and even more so to have it shared by them. It has become a very precious work to me.
