Sector 10 is a futuristic metropolitan city set years after a political quarrel sent the entire world into divided chaos. Silver, the platinum-haired assassin has lived in Sector 10 for many years now. Working for a member of the criminal-run syndicate, she executes employers almost every day without another thought. In Sector 10, high pay meant high risk. After a mysterious incident that happened years ago, Silver has lost all dignity and struggles to even keep up a conversation with anyone. Until a particular night, when she encounters a magnate named Jonathon, a man Silver labelled as "too soft-hearted for a place like this." Being the first person that Silver has let into her life for a while, she must balance out her life as an assassin and her relationship with Jonathon as gloom-ridden past experiences constantly flood back to her.
