Legend of DUO

In present day England, a war is being fought. The average citizen does not notice, but vampires are running rampant among the populace, and it's up to the Hellsing organization to contain the bloodsucker threat, using even their own weapons against them.

No one knows much about this mysterious figure fighting against the occult, but things starts to change after he “recruits” a new agent to the establishment...
