Bow Wow! Two Dog Night

is the first volume of the Etsusa Ohashi light novel series, written by Ryogo Narita and Illustrated by Yasuda Suzuhito. It was released under the Dengeki Bunko Imprint in December 2003.

Synopsis
A story presented by the combination of Ryogo Narita and Suzuhito Yasuda, who enjoys life while struggling in a lawless city.

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 Komagi, a weak and quiet boy, feels adventurous with his childhood friend. The important wanted criminal, Hayato Yui, should be attracted. And they begin to take a completely different path in a lawless zone isolated from society. However, the figure was like a dog barking in the mirror.
