Guts Ishimatsu

In 1969, a young man finds an anonymous letter in a glass bottle which foretold of the apocalyptic arrival of a cosmic monster known as Demeking. Since then, he has physically prepared himself in a lone struggle for that fateful day when the monster will arrive.

Four ex-samurai are hired to hunt down deadly ninja infiltrators plotting to destroy the Matsuyama clan in this remake of the 1964 classic.
