Vocaloids

A blonde anime girl with cat ears smiles with her hands on her cheeks against a brick wall, followed by a white-haired girl with cat ears laughing with her eyes closed in front of a bright circular light, then a red-haired girl with a snorkel swimming in water, then the same girl floating in a red and white inflatable ring, then a red-haired girl with a yellow headband looking forward, and finally three girls in school uniforms, one with blonde hair clasping her hands and smiling while the other two look on.
