Blood Bank is a must-read if you like yaoi, BDSM, or vampires.  The main character One is a human banker working in a blood bank.  In this world humans are completed dominated by vampires.  One normal day at work, Shell Overlord, the new leader of the bank, comes in and is instantly fascinated by One.  Their relationship develops from there with some cool role-switching and a very balanced relationship, even if the beginning it is a bit unhealthy.

The characters are very believable and I instantly fell in love with Shell's expressions.  One is more reserved but makes it that much more interesting to find his real feelings and motivations.  The world is decently developed and has a lot of potential for more stories.

The art is beautiful with great color choice and portrays the atmosphere perfectly with little effort.

The story is addicting and hooked me from the 1st chapter all the way to the 59th.  The plot may be forced at times, but the relationship between the main characters masks that well enough.  It's definitely one to pick up.
