Ninja in a Watercolor Subway Tunnel

An agile ninja wearing a dark hood and mask glides through a rain-slick subway tunnel, rendered in soft watercolor. The scene is atmospheric with washes of indigo, teal, and muted pink that bleed into each other. Neon subway lights skim the damp concrete walls, casting glowy reflections on wet tracks and puddles. Faint graffiti blurs in the distance while steam swirls around the ninja's silhouette. Convey dynamic motion with blurred brush strokes and diffuse edges, capturing secrecy and speed in a moody urban setting.
