Denkurō Tōgō (東郷 田九郎) is one of the original immortals from the Advena Avis. Though he was first mentioned in the first volume and later in the fifth volume, his actual appearance and introduction was not until the eleventh volume during the 1700s timeline. He was the only Asian aboard the Advena Avis, and is one of the ten surviving immortals in the 2002 timeline. He is an alchemist from Japan, who studied along with his good friends (and fellow immortals) Zank Rowan and Nile under the tutelage of Majeedah Batutah.
