I was in charge of directing the opening for the original TV anime *Shuumatsu Train Doko e Iku?*.

SOUL BUBBLE is an immersive art installation that visualises an individual’s mental and physical state. Inside a space surrounded by eleven screens, visitors sit on a single-seat sofa equipped with AI and sensors. The sofa reads changes in posture and centre of gravity, heart rate, breathing, and hand movements, visualising these signals in real time. States of mind and body such as relaxation, focus, tension, anxiety, excitement, meditation, and confusion are analysed and transformed into microbial-like patterns that spread throughout the entire space. At the end of the experience, the participant’s own behavioural data is projected onto the screens, stored, and used to advance the AI system. As more participants join, individual and collective data accumulate, revealing differences, distributions, and new tendencies. This ongoing process continually evolves the installation, forming an endless archive that keeps recording human states. Interestingly, many visitors were highly interested in their own results and came expecting to find a pattern of “high relaxation.” SOUL BUBBLE gently envelops the body like a bubble, while also presenting itself as a prototype for future sensing devices, where technology stays close to the body, responds to the soul, and brings to light the hidden layers beneath mind and existence.
