A supernatural romance manga series by Ohmi Tomu. It has been serialized by Shogakukan in the manga magazine Petit Comic since 2006, with chapters collected in six bound volumes as of March 2009. The 34th and final chapter will be published in the May 2009 issue of Petit Comic.

Midnight Secretary follows the relationship between Kaya Satozuki, a private secretary, and her boss, Director Kyouhei Touma of the Touma Company, who is a vampire.

Considered to be the "perfect secretary" yet constantly criticized for her ultra-conservative dress style by the Director, Kaya lives a seemingly normal life until she finds out that her boss is actually a vampire. Despite uncovering his identity, she dedicates herself to serving the Director to the best of her abilities. The early part of the story focuses on the trials and tribulations of Kaya's increasingly hectic workload, then shifts to the developing personal relationship between her and the Director.
