At first glance, Saya looks like your average Japanese schoolgirl.
However, there is something unique about her - she isn't real.
She is the creation of Teruyuki and Yuki Ishikawa are a husband-and-wife team of freelance 3D computer graphics artists from Tokyo.
They posted the images online, and have since seen them reposted thousands of times as people trying to answer the question of whether they are photographs of a real person or not.
"'I think I've seen her somewhere' or 'She looks like someone I know' are what people usually say when they see Saya," says Yuka Ishikawa, one half of the husband and wife graphic artist team behind Saya.
When the couple first posted pictures of the hyper-realistic schoolgirl online last year, it was a revelation about what can be achieved with computer design.
