ENEMY OF HUMANS

Growing up to become a typical salaryman, the only joy in Michael's life is playing shooting videogames, especially those wih aliens.

He knows nothing about alternate universes. He never watched an anime or read manga. He doesn't like reading.

So how is he going to survive in a parallel universe as the enemy of humans. We're not talking about aliens taking over earth, but residents of the world, trying to fight for survival.
