Synopsis
The largest bridge in the world between Sado and Niigata. An artificial island towering in the center that was never named-it was abandoned by the recession and turned into a lawless city just like Kowloon Walled City, where illegal immigrants and criminals live. Two men visit the island. Seiichi Tanuki, a weak and quiet boy, feels adventurous with his childhood friend. I hope that the important wanted criminal, Hayato Yui, will be attracted. And they begin to take a completely different path in a lawless area isolated from society. However, the figure was like a dog barking in the mirror.
