character: kikirara_vivi, A medium shot, eye-level portrait of Kikirara Vivi from hololive, centered in the frame against a festive, soft-toned background. She is beaming with a wide, joyful smile, her blue eyes sparkling with happiness. Her very long, multicolored purple and pink hair is styled into voluminous twintails tied with bows, with colorful streaks flowing around her. She is dressed in gyaru-inspired attire consisting of a white shoulder-cutout crop top that reveals a glimpse of her black bra, paired with detached sleeves and polished nail polish. She is gesturing cheerfully with her hands, as if celebrating, while "Happy Birthday" is written in decorative, celebratory lettering in the surrounding space. The visual style features clean linework, smooth and glossy skin tones, and gentle, pastel colors, creating a bright and celebratory atmosphere with a focus on her expressive, vivid eyes.
