Transmigrating to the Type-Moon world, Ryougi Shinobu becomes a magician. He initially thought his life would consist of fighting the Holy Grail Wars and occasionally saving humanity, but he gains access to a dimensional forum linking different worlds. Shinobu asks, "Can humans and demons really get along?" Ryougi replies, "Immortal demons are perfect experimental subjects, ideal for mining or working in nuclear-contaminated areas. Isn't that harmonious enough?" Ai Haibara asks, "I work for a cult, and they killed my sister. How can I get revenge?" Ryougi replies, "Take that drug that turns people into children, and I'll immediately scatter their ashes."... Members from different worlds constantly appear on the forum. While helping them solve their problems, Ryougi also collects some local specialties and earns a few hundred million points.

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.
