Yohko Yamamoto

Starship Girl Yamamoto Yohko (それゆけ!宇宙戦艦ヤマモト・ヨーコ, Soreyuke! Uchū Senkan Yamamoto Yōko?) is a sci-fi anime series based on novels by Shoji Takashi. There have been two 3-episode OVAs from J.C. Staff. The series was released in the United States by The Right Stuf International on DVD in 2003. There also was a 26-episode television series which as of July 2008 has not been licensed in the US.

The series is set in 2999 AD, where two factions - TERRA and NESS - are engaged in a space war game to control planets. They fight with spaceships, which have been made to teleport their pilots back to the mother ship upon destruction. This results in the battles having no true casualties. Since the reflexes of people in the 30th century have greatly deteriorated, a TERRA engineer, Curtis Lawson, uses a time machine to go back 1000 years in time. There, he recruits the four protagonists of the story to fight for TERRA.
