Yuki Kei

Japanese name:

有紀蛍

At only sixteen years of age, Kei is nevertheless ranked as one of the Arcadia's staff officers. After assaulting a military officer, she was rescued by Harlock when he raided the ship transporting her back to earth (and prison.) Her own family dead, Kei chooses to remain on the Arcadia and becomes her navigator and science officer. The youngest crew member next to the fourteen-year-old Tadashi Daiba, Kei makes it her business to watch over the hotheaded newcomer and try to keep him out of trouble, saving his life on numerous occasions. While far more levelheaded than he, she's not one to be trifled with, and is a crack shot in a gunfight, as well as a hell of a shamisen player.

Kei also appeared in both 999 films (on the green Arcadia now,) as well the Endless Road SSX series. In SSX, Kei becomes one of Harlock's crew after her father, a newspaper publisher specializing in anti-Illumidas propaganda, sacrifices himself to protect the Arcadia. She becomes a big sister to the young Revi Bentselle, and risks her life to obtain medicine to diagnose Tochiro's worsening medical condition. Within her subconcious, Kei holds the key to the Treasure Island of space, which may contain the secret to earth's salvation.

In the Endless Odyssey series, Kei has moved up the ladder to captain of her own ship and crew, but she is captured early on and used as bait, along with the Arcadia's other alumni, to draw Harlock into a trap. It naturally fails, and Kei afterwards rejoins the crew of the Arcadia.

An early Captain Harlock TV series book, written in english and obviously published before the show had been made, states that Kei has a good understanding of biology, and makes the badly-translated and hilarious assertion that "she helps Harlock biologically." However, she doesn't, either way you interpret it.
