Five years in hiding.

Five years in which Professor Kurou has thought only of revenge on the man who left him maimed.

The army is savage. It is deadly. It shows no mercy or remorse.

And at its head is a old foe, a man who will stop at nothing to see Professor Kurou dead.

Perhaps Kurou's chance for revenge will come after all ...
