A derivative work of Paradise, trying to wake up the sick mosquito. One year, a large-scale epidemic swept the Blue Star, causing the planet's population base to plummet, and coincidentally, the same thing happened in multiple dimensions at the same time. In the same year, in order to cope with the sudden influx of a large number of people, the neutral Void Tree activated the emergency regulation No. 19566: "Reserve Combat Force Realm" (real world). When the "observed units" enter the Paradise camp in advance and in large numbers during non-wartime, each Paradise camp can arrange for the "observed units" to enter directly or temporarily according to their own situation. The "observed persons" who are temporarily suspended must be arranged by the Paradise.
