Japan, distant year 1235. Deadly sword fights, unshakable rules of honor, submissive and at the same time strong Japanese women, gangs of robbers, Buddhist monasteries and Shinto shrines, seemingly impregnable castles, unusual clothes and shoes, strange foods and drinks... In this cruel and amazing world there was an airy gymnast Artem Topilsky. It just so happened. The country of Yamato imposes its laws, its values on Artyom, and an unenviable fate is in store for the stranger there. But Artem accepted the challenge of fate. Moreover, he is not going to vegetate as a wordless extra. He simply has to play big.
