Thanks a lot, is it from a game of sorts? It seems like the novel has gifs too. Seems to be by the same studio as this

If they're games, where can they be bought from? I'm thinking a digital download.

Most are only released in japan so you'd have to find a fan translation patch. Installing and runing them is also not always that easy. Font enc problems mostly.

You can download a trial version of the game here: http://eroge.jp/demo/omegastar/#Biman2
