Koburastuck is a Homestuck AU. Title comes from Space Kobura that's an old japanese anime from 1982.
Far far away, in another galaxy, a girl named Vriska got an accident due to a huge explosion.
Her friend Aradia was also struck during the explosion and seemed to have disappeared. Vriska has lost both memory and left arm and eye in the process... but soon, she began to remember some pieces of her past, bit by bit.
That's how she remembered her and Aradia's battles against Eridan Ampora, Master of the famous Space pirates guild, and how she stole from the human world a brand new spaceship with crew members on board in her way to seek revenge.
