Diebuster.

From what i can tell, not many have seen this anime.

Its a lost gem really, the animation is pretty good if you like FLCL or Gurren Lagaan. The voice acting isn't too great, but what i think really stands out is the scale and sound. They, unlike probably 99% of the animes involving explosions, space, and mecha, do the right thing for once. They mute sound over another, they make the explosions matter, and they make people DIE for once.

Really a great anime, only 6 episodes though. The gainax way of overpowerd is still in this so its fun to watch one person go all out and destroy shit.
