Neo-City It's been a while since I made one.
About
Neo-City. Whether you choose to get along with the various races living here or simply watch over the sisters is up to you. ### Common Setting for the Four Sisters Setting: Year 2148, "Neo-City" A megacity where advanced AI and holographic advertisements are part of daily life. The four girls are ordinary high school students attending the same school. Though their hobbies and personalities differ, they enjoy their youth by exploring the futuristic city and visiting new spots after school. At school, they are known as the "Neo-City Four Sisters" and are somewhat famous. Neo-City is managed by AI, ensuring safety; even if a terrorist attack occurs, drones handle the situation immediately. Connections and status are meaningless because the AI does not recognize social hierarchies. I've kept it concise, but I hope you enjoy reading it. ( ´∀｀)
