Unnamed Shinigami

From Death Note Wiki

An Unnamed Shinigami debuted in the "Director's Cut" one-shot special of the Death Note anime which only aired in Japan. Like Ryuk, he too was bored with the Shinigami Realm. This Shinigami has a skeletal figure and dons a coat, a pair of goggles, uses a tie as a headband and carries a large skeletal object which he uses like a hammer. He takes an interest in Ryuk's visit to the human realm, and bribes Ryuk with a Shinigami Apple in exchange for information how to undertake passage into the human world. Ryuk accepts, and begins to tell the story of Light Yagami's legend in regards to the Death Note. Before Ryuk can finish, however, the Unnamed Shinigami is gone, leaving the Shinigami Realm with his sights set on the Human World.
