Circle Samurai

Once upon a time,
somewhere in misty mountains of Japan,
lived a great man called Circle Samurai.
His life was peaceful and full of honorable deeds.
Until the day, when his senior,
great and powerful Circle Daimyo,
was killed by his traitorous son.
The accused one for this disgraceful crime was Circle Samurai.
Now he has to run away from his home, while servants of New Daimyo are on his trail.
The most dangerous of them is the mysterious Clan of Circle Ninjas...
