In the distant future of planet cracking, VR distraction, and corporate greed, grieving private detective Ryoma LeBeau takes what seems to be a simple job on the opulent casino planetoid of Scylla. Captivated by a chance meeting with the cybernetic musician Guin, he finds himself drawn to the smoky anachronistic lounge bar where they perform. But it seems there's a lot more to both Guin and this case and Ryoma can't help but pull at the threads of mystery leading him to the depths of conspiracy and memory. Inspired by Philip K Dick novels and Ghost in the Shell, Synthetic Sea is a cyberpunk noir entwined with queer romance.
