The oldest sister, and leader of the Red Snappers. Blonde-haired, she is proud and strong. She and Yohko are rivals, both in starship battles and in love. Rouge admires Fluger, and seems to owe him a debt of gratitude for helping her family. Although she almost beat Yohko in their first space battle, she was stopped once Fluger realised she had removed her automatic teleportation module - the device that would teleport her out should her starship be destroyed. Yohko defeats Rouge in their next battle. While the Red Snappers were stranded on the 'Boiled Egg', Rouge is trapped and finds out that Yohko comes from the past. She challenges Yohko to a duel, hoping to keep Yohko in the past. However, due to an emergency, the fight is inconclusive. In the end, they race each other on foot, with Yohko winning. She pilots the Red Snapper Superior, which is equipped with the Ultimate Impulse Cannon, a weapon that is comparable to Yohko's Everblack Cannon. Like the other Red Snappers, her name is related to "red": in this case, rouge is the French word for "red".  Source: Wikipedia

There is an ancient legend on a distant planet which states (among other things) that four goddesses will one day descend from the skies and all will be right with the world. 
Of course meanwhile, Yohko and the rest of the Terra team (with one straggler) have crashed on a backwater world, and they have to figure out a way off before their new charge... gets hungry again! 
Every so often, a celebration takes place in one of the most beautiful places in the Universe... a cosmic Sakura fest! Since the Terra Team has been doing so well, one of them is invited to join the high command as they meet their opposite numbers from NESS. It's a time of celebration and a time of peace... but it seems that someone didn't get the message.

In the year 2999: humanity is split into two factions, Terra and Ness, in a war fought by starships. One of the foremost of the pilots is the cocky teenager Yamamoto Yohko, and during one of her missions, she and her crew are sucked into a temporal anomaly (a la Star Trek) that sends her back to our time. Amnesiac, she only thinks of herself as a typical high school student - until a course of events sends her back to her ship the TA-29, with her newfound friends fighting at her side in a war that looks suspiciously like an arcade game (complete with 100 yen ignition costs!).
