Denkurō Tōgō

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.

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

1705: The Ironic Light Orchestra
Denkuro and Zank Rowan enter the city of Lotto Valentino in hopes to stopping the circulation of a certain drug in the city, and after shortly entering they are met by Spanish aristocrats - the Rotten Eggs - who were beating up Elmer C. Albatross and Niki. Inadvertently getting involved because of their odd appearance, they easily dispatch them, while Elmer and Niki escape.

Later they encounter Huey Laforet who agrees to bring them to Dalton. Their they discuss their encounter with The Rotten Eggs, and Aile (whom Dalton doesn't know), while Elmer and Huey eavesdrop on them.

2001: The Children of Bottle
in 2001, Elmer explains what happened to Denkuro ever sense the 1700s. Desiring to return home, while avoiding Szilard, Denkuro opted to take a trek over the North Pole, where he was frozen for many years until he was finally defrosted in the year 2000. When he returned home he met with Elmer.

Trivia

 * Judging from certain novels, it seems like Narita originally planned for Zank to be Denkuro's brother, since he is referred to as Zankuro (in 1934: Prison Episode Alice in Jails) and as Denkuro's brother in another. This idea was retconned.
