During WW2, the Nazi and the Japanese were well known for conducting Human experiments.

While we have had many Hollywood movies regarding the Nazis experiment, the cruel Japanese human experiments and its unit were much more secretive.

Regardless, this show is basically a What if the Japanese had succeeded in creating monsters.

Besides this, not more of the cruelties and war crimes were shown or mentioned, showing a rather tame and orderly Japanese occupation when this was not the reality of the occupation.

The show is packed with action if you skip episode 1, which really has no purpose besides setting the background of the world and the characters purposes for taking action.

Typical of an action drama, the plot is nothing to write home about but the action scenes are well worth your time

If you skip episode 1, you're in a really good action drama.
