In 91 AS., Kishiro Technologies achieved a breakthrough in the development of quantum circuitry that revolutionized the entire economy almost overnight. Just as its founder had originally planned, Kishiro products found their way into almost every consumer, commercial, or military product on the market -- including those made by Samura. With their new found capital, Kishiro Technologies rapidly expanded their manufacturing capabilities and established the Yukawa Shipyard within the nearby Honshu system, devoted almost exclusively to the construction of ships to be used in gas mining operations in the nearby Crow Nebula.
The second company had far more humble origins. In 10 AS., a small research company, headed by Katsuhiro Kishiro, genetically modified an existing earth fish species and introduced a super-breed optimized for life in New Tokyo's alien ocean waters. He also tackled the rice problem. The soil conditions were quite different than Earth, lacking certain nutrients that rice brought on the sleeper ship needed. Again, Kishiro came to the rescue, this time with a new rice strain that could handle the harsh growing conditions found planet side. Kishiro won the adulation of the Kusari imperial family, and thus began the second of the two industrial dynasties of Kusari. Adapting the name Kishiro Technologies for his company, Kishiro espoused a progressive research oriented environment that relied more on brains than sheer size and intimidation, unlike his primary rival, Samura.
Kishiro thought he’d finished the series in the 1990s — ending that novel-like storyline with a lovely, satisfying Gally-saves-the-world finale — and had moved on to other books.
