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.
