To date the Crows manga series has never been translated into English.
As far as I know domestic licensing rights have never been secured and it's doubtful they ever will be. Thankfully scanlators have taken the task into
their own hands. Volumes 1 and 2 of Crows originally translated by Delinquent-Manga and
Minna-Scan can be downloaded below.
All Crows chapters starting with Volume 3 are currently being translated
by the scanlation group Paula And Dangerers. All P.A.D. releases are available for direct download. Future releases will also appear on
this page as they become available.
