A blind boy named Shinobu lives a peaceful life with the support of his kind teacher and girlfriend Mikoto, who trains daily to learn the ancient martial art of self-defense known as "Mibuchi Toshujutsu". This is so until one day everything is stolen from him when a strange visitor shows up in his dojo. This man defeats both Shinobu and his master and kidnaps them.
Three years have passed, and to get his girlfriend back, Shinobu emerges from the depths of desperation and finds himself in a prison on a remote island that houses the most dangerous criminals. Nothing can stop the wrath of a man whose girlfriend has been stolen! Even blindness has become less of a problem for him!
