Ten Seconds of Guilt

Taken place in 1898, Mikasa Ackerman is the most feared assassin in Victorian England. She works under the command of Erwin Smith, who happens to be one of the wealthiest yet kindest people known around those parts. With the help of Annie Leonhardt, the headmistress of the Trost Brothel, and Eren Yeager, the lovestruck owner of the Shurke Blacksmith, Mikasa will learn the difference between admiration and love, and how dangerous all of it can really be.
