"Year 2150: Eight years after the murder of Akira Kimura, Water City's renowned scientist and anointed "God," the nameless antihero who once risked everything to find Akira's killer is no longer a detective, but a stay-at-home dad. While his wife climbs the corporate ladder of the Water City Police Department, he raises his now nine-year-old daughter and occasionally takes the odd job as a bounty hunter. Water City's domestic bliss is threatened when Ascalon's Scar--the permanent mark left by the elimination of Sessho-seki, an asteroid that nearly wiped out life on Earth--vanishes from the sky and a familiar face thought dead returns from the ocean depths to exact revenge on humanity. What follows is a wild journey, both deep below and high above a Cat City (formerly Osaka, Japan) to the moon and back, all to stop the destruction of the last of the human race."--Provided by publisher.
