character: mizumiya_su_(1st_costume). This is a medium shot, 3/4 view from the front-left, featuring Mizumiya Su sitting on an outdoor stone staircase. She is positioned with her legs drawn in, knees pointing inward in an "inward-turned" (uchimata) pose, resting her hands casually on the step beside her. She has long, multicolored blue and pink hair with distinct streaks, styled into low twin braids with a lightning-shaped ahoge. She is dressed in her signature outfit: a white jacket worn over a blue shirt, paired with short blue shorts and a black thigh strap. Her expression is calm and natural as she looks toward the viewer. The environment consists of a sunlit outdoor staircase with weathered stone textures, flanked by soft greenery and daylight filtering through nearby trees. The visual style is a high-quality anime illustration with clean line art, vibrant colors, and a bright, airy atmosphere.
