Create a highly detailed wide-angle anime sci-fi cityscape inside a completely enclosed {argument name="space habitat type" default="O'Neill cylinder colony"}, viewed from an elevated perspective looking down the length of the cylinder toward a hazy circular vanishing point. The interior surface curves upward on both sides and overhead, packed with dense Japanese-inspired neighborhoods, apartment towers, small houses with red and blue roofs, elevated roads, pedestrian streets, parks, trees, canals, and rail lines. A bright central axial light system runs through the middle of the cylinder as three long glowing white-yellow strips, casting soft atmospheric light and creating a deep sense of scale. Include one visible elevated train on the right foreground track, many tiny pedestrians and vehicles, and warm lit windows throughout. Add readable urban signage including 3 Japanese-style residential district signs, 1 ramen shop sign, and 1 Neo-Kyoto sign, integrated naturally into the city. Use {argument name="visual style" default="clean detailed anime line art"} with crisp ink outlines, cel-shaded colors, intricate architectural detail, slight fisheye perspective, blue atmospheric haze in the distance, and a lively futuristic {argument name="city name" default="Neo-Kyoto"} mood. The scene should feel like an impossible enclosed space colony, not an open sky city, with the full cylinder shell visibly surrounding the entire metropolis.
