Zombie Groove

A new virus that reproduces through dopamine in the brain has emerged. Once infected by the virus, the humans become dancing zombies due to excessive dopamine secretion. When I finaly opened my eyes, I am in an hopistal, surrounded by dancing zombies as I also almost turned into one. Fortunately, a special device attached to my body suppresses the virus' growth, but energy extracted from the zombies is required to maintain the device. It is now my fate to constantly hunt zombiers in order to not turn into one myself.
