The group that leads the attack on Nobunaga's castle is made up of characters from throughout time, space and the big screen, so Tomokato must travel all over the Earth and beyond to seek his vengeance (from Japan to Camelot to Valhalla to Mars, to name just a few) in the most violent ways possible, involving the deaths of hundreds of beings.
In the first book, The Adventures of Samurai Cat, Rogers skewers J. R. R. Tolkien's Middle-earth, H. P. Lovecraft's "The Shadow Over Innsmouth", Robert E. Howard's Conan the Barbarian, and Norse mythology.
With the second book, entitled More Adventures of Samurai Cat, Rogers goes after the movies (while still referencing pulp literature), satirizing Indiana Jones, and fusing it with King Arthur and the Knights of the Round Table in the search for the Holy Spad (a biplane armed with two 15 mm machineguns and God's own special effects (Celestial Lights and Magic), complete with 3D glasses for safe viewing).
By the third book, Samurai Cat in the Real World, Rogers take on historical figures like the Third Reich, Chicago gangsters, and finally Joseph Stalin and the Communist Party.
Desperate for work, he reluctantly accepts a job: to kill a supposed white demon cat named Tamanojo, who is said to possess a magical charm that makes its owner completely infatuated.
