Bloodsuckers includes several previously released singles that were re-recorded or re-arranged for the album, such as "GET AWAY," "THE JOLLY ROGER," and "VAMPIRE'S LOVE." The international version notably included "ZERO" as a bonus track.
Upon its release, Bloodsuckers received attention for its aggressive sound and polished production, further cementing Vamps' reputation as a powerful live act and studio band. The album was supported by extensive touring, including international dates, which helped to expand their fanbase beyond Japan.
