宇宙活動 / ハイテクノロジー

A donut-shaped space colony supported by Tokugawa. It is a smaller-scale colony, with a maximum population of around 10,000 people. Also known as the Tokugawa model, since it has been created almost solely by technology developed by Tokugawa. All space colonies currently under construction are torus colonies, the largest torus colony built so far consisting of 4 levels.
