This artwork begins when crows emerge from a space, crossing the boundaries of other artworks, flying in all directions and influencing other works. Then, the crows enter another space and continue as a new artwork.

Flocks of mythical crows (Yatagarasu) drawn with light fly around the space and their trajectories become trails of light, forming Spatial Calligraphy. The chasing crows are eventually chased themselves, and form flowers when they crash into each other, scattering their petals. Although the crows usually avoid crashing into people in the space, when they happen to do so, they similarly form flowers, their petals scattering.
