Hideyuki Kikuchi's Vampire Hunter D Vol. 6 (manga)

The Nobility have captured a young Frontierswoman named Tae and held her captive for 8 years, and her prison -- the remote Castle Gradinia -- can only be accessed by those brave (or senseless) enough to cross into the no-man's-land known as the Outer Frontier. The mysterious "people finder" Granny Viper has been charged with the recovery of the girl...but can she trust her hired escorts, the notoriously shifty Bullow Brothers? In a race across treacherous terrain, it will be up to D to lead the charge and level all enemies on this rescue mission!
