The character in my profile is Raika Grace.
She is but one of many female characters from a long line of ancient Japanese adult PC titles released in the mid to late 90s / early 2000s from a (now non-existent) company called Sogna.
Here is more detail regarding that character:
For more info related to these old, irrelevant, outdated adult titles from yester-year, just visit the Sogna Digital Museum.
(Just a protip, there are far better adult titles available now from Japan that are fully animated and voiced. However if you simply must have the animated GIFs from all of Sogna's releases, you can probably find them on image sharing/dump sites such as Danbooru or Gelbooru. Just Google search them)
