"That must have been towards the end of the Chivalrous War." Kanhara Kotoba reminisced, "Kocho Ghana in Africa... Do you remember that city? The one Uncle Xiang invested in building... Are there still records of it online?"
The city was also an initiative started by Xiang Shan in the '50s to build a "better future." For Xiang Shan, Africa really was a good place. Superman Enterprise had many large biological experiment zones there. This hot and humid region was the most suitable area on Earth for metal-based lifeforms to thrive. Superman Enterprise also produced several researchers who came from here.
However, the main reason Xiang Shan built his "City of the Future" in central Africa was, cough, the relatively lenient political environment.
