Denkurō Tōgō

Denkurō Tōgō (東郷 田九郎) is one of the original immortals from the Advenna 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 mentioned as being the only Asian on the Advenna 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 who would later also become immortals) Zank Rowan and Nile.

Personality
Denkurō speaks in a very formal manner, calling everyone "Master" or "Mistress" and referring to himself in the third person.
