Night in a cyberpunk near-future city. Mio, a high school idol, is dynamically sliding on a hologram stage illuminated by neon lights, holding an SF-style energy rifle in one hand. The rifle is a translucent blue glowing hologram gun, with the muzzle pointed in a safe direction, creating an atmosphere like a hero show's finishing pose rather than an attack. Mio shows a duality with a bright, sun-like smile and a slightly cool gaze. Neon letters "HAPPY BIRTHDAY MIO" and "4th Anniversary" shine on the hologram billboards in the background, and floating holograms of cakes and balloons surround Mio. Her cyberpunk outfit consists of a bodysuit and jacket based on black, neon blue, and neon pink, with glowing lines, knee pads, and boots for sliding.
