It is the year 2500. After several years of war, the space colonies and earth have made a breakthrough in peace to further advance humanity and let it flourish. One of their first acts is to make other planets habitable so humans can live more comfortably and find new methods of energy as fossil fuels ran out long ago. After several decades Saturn is made hospitable as are several other planets. Soon more than 6 planets are made hospitable but peace seems to have only lasted so long. A new form of metal is found on Saturn and is stronger than any metal on earth. Its properties are similar to gundanium but still less powerful and less durable. Earth claims that since it started the project that the new metal dubbed "Star Stone" is rightfully its and the Space Colonies. The settlers believe it to be theirs after all the work and searching they did to uncover the metal. After a few of the Earth's military soldiers come to take the Star Stone are attacked by anti-earth radicals, Earth declares war on the new planets. While the fighting is going, Katze Akechi a 19 year old ace pilot, and his best friend and girl friend, Amy Yawamoto an 18 year old medic and mechanic, have started an underground resistance movement. Katze goes to several military bases and steals multiple mobile suit blue prints as well as the mobile suits themselves. After several successful raids Katze steals 4 Gundams. Katze himself chooses a red one who's specialty is close range combat but is accurate with a gun as well whom he nick names Red Devil. They plan to end the war, by force is necessary before things get out of control and irrevocable mistakes get made.

Katze sighs as he opens his eyes and sits up while on his bed. He sleepily hits the off button on his alarm and stretches. "Another day, another mission." He says to himself sleepily as he looks out the window to see all the mobile suits he stole. There were only 100 suits but there was no one to pilot them. "We really need to get some recruits soon. Otherwise we won't have a shot at ending the war let alone surviving it." He said to himself before knocking on the door across from his room. "Amy, time to wake up and check if the word got out. I'm going to go train with Red Devil." He said with a slight smirk. He was hoping that the secret message Amy put out to the resistance got through and they would send over a few mobile suit pilots. He was also happy to be able to test out Red Devil. It was only a month ago he stole it and he hadn't used it due to the fact a search was out for it. That was until Amy made a fake Red Devil and had a video leaked that showed it being blown up by a masked stranger. Now that the Earth's military was no longer searching for it he knew a spot he could train. "Not so fast Katze." Amy said with a stern sounding voice. "Before you even think about piloting that thing you have to eat and suit up first." Katze sighed as he got some cereal and started to eat. "I don't see what the big deal is. A gundam is just a stronger mobile suit and I can handle those in my sleep." He said cockily before she smacked the back of his head. "No it isn't Katze. They are more advanced and more dangerous. Last thing I need is to see you come back in a body bag…" She said before turning his back to him. Katze then got up and hugged her from behind. "Listen….I know you worry about me and I appreciate it. But you don't have to worry so much because soon this war will be over and we can live top side again and make lots of friends and have a family. I know you're upset because we lost our parents but we are still alive. I won't allow their sacrifices to be in vain and I know you won't so for you I'll take it easy this one time." He said with a small smile before kissing her cheek lightly. Amy smiled and turned to him. "Alright, but if you get hurt you have to cook dinner and clean every mobile suit and make them shine." She said with a playful smile. Katze laughed a bit and winked at her. "You got it." He then quickly put the dishes in the sink and put on his red and black space suit and carried his red and black helmet to the cockpit. "Alright Red Devil, Time to get to know one another." Katze then put on his helmet and started up the gundam. "Red Devil launching."He shouted before taking off into space with an eager smile. Amy shook her head and chuckled. "Katze you're such a kid." She said to herself before checking the email. After reading a few junk mail she saw an anonymous email responding to her cry for help. She smiled and knew Katze would be happy but decided he would go get them in case it was a trap. She then leaned back and saw Katze had left the dishes in the sink and some food out. A small vein appeared on her head as she started to clean. "If it's not a trap and he comes back alive with some troops I'm going to show them what happens if they don't pull their weight by making an example out of him." She said angrily to herself.
