My cutie Saiyan twins, Krema and Tamegi, drawn by the lovely <3

Six years before the destruction of Planet Vegeta, a Saiyan Warrior named Niragi discovered the Planet Gyuu and "conquered" it. As masters of ki control and manipulation, Niragi sought to strengthen his bloodline by pairing with one of the native females, a "Gyuuman" named Yoguru. Naively believing that Niragi would stay and join their temple as a monk, Yoguru eagerly accepted. Their pairing bore twin Halfbreed Saiyans, with tails like their father.

Tamegi, born only minutes ahead of her sister, was given a Saiyan name to reflect her heritage. At a young age, she had become a talented fighter, already managing to keep up with her experienced father. The younger twin by only minutes surprised Niragi, who had not been prepared for a second child. Unable to think of a name himself, Yoguru named her Krema, a Gyuuman name. As the two children trained with their father, Niragi found that Krema was disturbingly weak, and yet had mastered flight and energy manipulation astonishingly fast. Regardless, Niragi viewed Krema as a failure, preferring to focus on the more tenacious and prodigious of his daughters. And yet, despite her ferocity and skill, Tamegi could barely maintain flight, let alone summon energy blasts or fight in the air.

On the fifth anniversary of their birth, Niragi showed Tamegi the Saiyan pod he had come to the Planet Gyuu in, and took her to their homeworld, Planet Vegeta, smuggly lying that they would return for Krema with a larger ship at a later time. Tamegi was able to adapt to their homeworld's heavier gravitational pull, but couldn't muster the strength to fly, and was still unable to maintain or wield her ki. Even worse, she was prone to outbursts that caused her to lose all sense in a raging temper tantrum, uncontrollable despite Niragi's best efforts. This only worsened with Lord Frieza's command that all Saiyans return to Planet Vegeta immediately. Despite promising to return for Krema, Niragi made it clear to Tamegi that he viewed her sister as a failure, and was best left forgotten. Enraged, Tamegi mustered the strength to fly just long enough to steal a ship and escape, undetected among the enormous number of other ships entering the atmosphere.

Returning to Planet Gyuu, Tamegi spent time with her mother and sister trying to learn how to control her ki, but to no avail. And yet, Krema's mastery of her ki had only improved tenfold, despite being physically weak. In time, they would discover that together, they would be stronger than either could possibly imagine.
