Hikozaemon Tokugawa

the middle-aged, balding chief engineer aboard Yamato and an old comrade of Juzo Okita. He left behind a grandchild on Earth of whom he is extremely fond. Determined to remain at his post no matter what happens, he suffocates in the last episode of the second season as the engine room fills with fumes.

His Japanese name comes from shougun Tokugawa Ieyasu.
