Hello1103 is an audiovisual unit consisting of Katsuhiro Hitomi (Trackmaker / Engineer) and yukako (VJ / Vocal). They combine organic digital sounds with visual expressions that manifest the subconscious, creating an otherworldly, immersive space.

Placing strong emphasis on live performance and expression, they go beyond conventional live setups — producing immersive VR live experiences in live venues and special events that merge 3D sound with live performance — pioneering futuristic forms of music through advanced technology.

As a supporting act, they also serve as VJ and manipulator for world’s end girlfriend, contributing to the music’s sensory depth through both visual and auditory dimensions.
Additionally, yukako has provided VJ and visual production for numerous other artists’ live performances.
