Well dispite similarities to Hellsing, this seems like it could be a pretty intense series. I'm gonna try to check out the manga. The way the main character talks, and the way he handled himself in the cockpit scene gave me a Vash-esque feel.

But anyways, Revquest-AF-F is the way to go. Mahou isn't too bad either but their filesizes are slightly bigger (around 50 MB), plus they don't give that sweet little history lesson.
