(This is actually a time-travel novel, but the person traveling through time is not the protagonist) Also known as "The Story of the Tactics of Rogues from Another World"
The ill-tempered Belia Borg was abducted by an unknown group of people when she was four years old and used as a guinea pig in a cruel experiment. As the only survivor of the experiment, Belia sets out to find the person behind her murder. During this period, she met the cheerful Hilo, the humble Ryan, the calm Nisset, and the elusive teacher, the ancient elf Alivia Stargazer. Accompanied by them, Nancy's road to revenge is full of laughter (?).
