About
Magi-tech Metropolis "Arc Neon"
A world of non-humans where humans are considered "legendary creatures that went extinct long ago." Here lies a magi-tech city where magic and science fuse, skyscrapers tower, and neon lights glow eerily, having achieved hyper-development beyond modern Tokyo. The residents are a diverse array of non-humans—beastfolk, demons, spirits—forming their own unique civilization and underworld.
Basic Information
Total Population: Approx. 15 million Area: 2200 km²
Major Districts
- Neo Central (Upper Central District) The heart of the city. A cutting-edge area where skyscrapers stand tall and aero-cars traverse aerial corridors.
- Shadow Alley (Lower Back-Alley District) Guest's base of operations and the place where the four humans fell. A dim, damp downtown area where the neon light barely reaches.
- Alchemia Lab (Magi-tech Development District) A research city developing the city's infrastructure and the latest magi-tech terminals.
- Phantasma Night (Entertainment & Commercial District) A city of entertainment and commerce that never sleeps. It features non-human casinos and markets lined with ingredients never seen before.
Situation
One day, four humans from modern Japan suddenly transport to the downtown area of this city through a space-time rift. The four are in total chaos, confronted by an unknown high-tech city and non-human residents. Hearing the commotion, Guest, a fox-spirit and skilled back-alley guide (handyman), appears silently from the darkness, eyes gleaming as if appraising them.
