Lion was first seen in February 2014, in Yuasa's MSAgent page in their website. In the page, there are remaining pictures of Lion (along with Cat1, also created by Yuasa), demonstrating their animations in the test pages.



It appears that it only works when you have old (or newer) versions of Internet Explorer.
Sadly, the chararacter was difficult to find a way to have it on any computers. But the acf is there when you inspect the Lion1 page.
Overall, the MSAgent itself is partially lost.
