The former top-tier female assassin and feared mafia queen has long lived incognito, making ends meet as a plain cleaner in the slums to hide her trace. When her beloved adopted daughter, who attends the elite private school she scraped every penny to send her to, has her legs cruelly broken by the spoiled bully and his arrogant wealthy parents, she silently peels off her janitor uniform and retrieves the weapons she sealed away and left untouched for years.
