Vampire Master Dark Crimson (Vampire Master ダーククリムゾン, Vanpaiya Masutā Dāku Kurimuzon) is a Japanese manga series by Satoshi Urushihara which was serialized in Monthly Magazine Z published by Kodansha.

The story is set from before the dawn of time, since which people (identified as Crimsons) have been under control of a deadly foe (identified as Clients), who considers themselves gods. At the end of the 20th century, the Crimsons still fall under the domain of the Clients, powerful beings who survive by making sacrificial offerings of live human people.

The protagonist is Shion, a child who is half-Client and half-Crimson, i.e. a vampire. He has chosen to fight ceaselessly against the Clients. He is aided by his companion, Rain, a human girl who acts not only as his ally, but also as his source of nourishment and lover. During a mission, Shion meets Helen, a young girl whose family fell victim to the Clients. He makes a blood oath and takes Helen as one of his followers.
