Yami no Aegis

Tate Karito is a freelance bodyguard and former operative of the National Police Agency's Special Assault Team, who's a bit of a Secret Keeper, and has a high-tech artificial metal arm that serves as his weapon of choice. With a shady past and a penchant for protecting anyone, so long as they solve his bosses' riddles and can pay his fee, Tate follows whatever path is laid before him.

"Zero: God created Adam from a lump of earth; Eve was created from Adam's rib. Death is nothing but returning to the start of life. Therefore, I mutter prayers... "Ashes to Ashes, Dust to Dust"."
 * Artificial Limbs
 * As the Good Book Says...: Zero does not quote directly from the bible, but his monologues have biblical motifs.

 * Elites Are More Glamorous: The National Police Agency's Special Assault Team. And yes, they're the elite civilian anti-terrorist/crime unit. Like most elite military/police units, their names are protected so no one knows who they are.
 * Even Evil Has Standards: Zero helping out an ex-hacker by killing the yakuza group after being kidnapped.
 * Uno, an ex-JGSDF soldier who specializes in hunting humans in his officer days, puts down his K-9 dog after being wounded by Tate. He has less respect for humans, however.
