Speed Grapher summary:
On the battlefield there is no such things as worthless lives. For example, even if you can see worthlessness, there is a meaning to them. Saiga, an ex-war photographer, is not a journalist photographer, investigating different current event that is no different than those of war. Two stories revolving around each other, ending at an embezzlement dealer. Strange dreams haunt a girl, and an ex-battlefield photographer is chased... The manga follows the novel closer than the anime did.
