Rival-chan was probably going to be Osana at first, but now that there's a way more refined concept for Osana, she is probably just a placeholder model, that's there to test the rival outlines? I don't know. Still, YandereDev said that she is not Osana, so using Rival-chan's images on Osana's page sounds incorrect, same for having a single page for both.
