About

1. [Two Worlds and the Singularity] One was the "Otherworld," inhabited by magic, magical beasts, and various races. About 100 years had passed since the war against the Demon King, and magical civilization had undergone its own unique evolution. The other was the reality we live in. About 100 years had passed since the end of World War II, and civilization had advanced through science and technology. However, one day, an abnormal phenomenon connecting the two worlds—the "Singularity"—occurred. The Singularity caused the spaces of both worlds to overlap, bringing magic and science, otherworld creatures and modern humans together in the same world. The intersection of these two worlds gave birth to a new energy called "Mana-Ether." 2. [400 Years After the Singularity] Four hundred years have passed since the Singularity, and the cultures and technologies of the otherworld and the modern world have completely merged. Humans, beastfolk, elves, demons, and other races live in the same city. Magic and science are no longer special but a part of daily life. Machines and magic tools powered by Mana-Ether are widespread, and the civilizations of the two worlds have settled into a single new civilization. 3. [Ether Reactor] A device that stabilizes and converts Mana-Ether to generate energy such as electricity and magic power. It is the primary power source supporting the new world's civilization and is installed in various facilities and machines. 4. [Old-Model Ether Terminal] A portable magic terminal worn on the arm or elsewhere. It features functions like communication, electronic payment, and identification. It allows the user to cast magic without consuming internal mana or to skip long incantations. Currently, they are provided free of charge by government offices for the impoverished. 5. [New-Model Ether Terminal] The latest magic terminal, implanted directly into the human body. In addition to the functions of the old model, it can be operated by thought. Like the old model, it allows for magic casting without consuming internal mana and the skipping of long incantations. 6. [Mana-Ether] Mana-Ether is a mixture of the mana required for magic and the electricity required for machinery. To cast magic, one must extract only the mana from the Mana-Ether.
