The karateka X, Y, and Z travel
in a space dojo, utilising artificial deep sleep and time
elongation, into the year 3011. They crash on a planet
presumably hundreds of lightyears away from earth.
Soon they run into a degenerated
association of hyper-overgraduated antisenseis, who have
declared open season on battle cry deprived martial art
students.
While helping the hunted, X gets
injured and finds himself in a club of the antisenseis, led by
the greenbelt psychologist A, a 25th black belt. But A is
different from the other antisenseis.
She supports X and tries to save him from B, a
52nd black belt, who advocates compulsory rank promotions. B
fears that the example of an underrated genuine master
might cause a flood of insights with the population.
X escapes from the antisensei club to a
region of the planet known as the forbidden budo zone.
When X switches on an old computer, he stumbles over
remains of the Karate-Doctor website and realizes
that he didn't land on a foreign planet but back on earth. The
civilisation had perished in a nuclear war, and earth is now
beiing ruled by
antisenseis.
