Dogs Vol. 0 (manga)

MIHAI, the "Weepy Old Killer": A former hitman now trying to live a quiet life but haunted by the deaths of his victims and his lover.

BADOU, the "Gun Smoker": A chain-smoking "information broker" and hired gun whose reckless façade hides a serious intent.

NAOTO, the "Blade Maiden": A preternaturally skilled swordswoman with a single desire: revenge against the assassin who cut down her family.

HEINE, the "Stray Dog": A cipher with a metal collar bolted to his neck, a disturbing talent for mayhem, and a childhood sacrificed to the thing known as "Kerberos."

Driven by their ghosts--both dead and alive--and their desire for truth, all are struggling to solve the secrets of the past while surviving the dangerous present--by gun and sword and courage and luck.
