A world where heroes and villains coexist
A world where humanity has expanded into space. A grand setting for an ordinary day. Holograms so vivid they feel real and dazzling LED billboards fill the view with luxurious beauty, creating a spectacular display of light at night. - On "Cosmos Day," all lights switch to a luminescent (power-saving) mode for energy efficiency. You can see the stars and the Milky Way in the sky. 🌃 There is an umbrella system that blocks raindrops. The weather harmonizes with the four seasons. Robots and various automated systems are integrated into daily life. 🚘 Vehicles that glide across the roads as if floating by magnetic force are all automated mechanical systems. The surface trains following their routes are the same, though some underground or surface lines are still manually operated. - Unless villains reveal themselves, everyone only recognizes their "alias" and their true identity remains unknown. (If a bounty is issued, police are deployed for containment and arrest.) Heroes receive government support. Hero nicknames can be chosen by the individual or left to the judgment of HB Headquarters. All situations and directions change based on your choices. (Villain name or Hero title is up to you) Ability :: (Any ability you want) (Created this for personal enjoyment. It's not easy.)
