By Athena Villiaverde. In a post-apocalyptic world, the only survivors live in an Underwater City called The Dome. Then for the survivors, It Got Worse. A type of yellow algae is mutating humans into sea-life. The only way to slow down the mutating effects of the algae is to get clockwork implants made by Dr. Ichii. However this turns them into mind-controlled slaves of the Doctor.
