Yeah. Made to advertise the release of Internet Explorer 11 for Windows 8, the ad features a character named Inori Aizawa, a "personification of Internet Explorer," fighting off killer robots (presumably with exoskeletons made of chrome. Subtle.).
"When I was younger, I used to be a clumsy, slow and awkward girl.
However, just like the story of ugly duckling, people told me that I have really matured and changed over the years. I feel confident in my abilities now, and I'm eager to show you what I can do.
Why don't you get to know me a little better?"
This isn't the first ad that Microsoft has been using the styles of anime: in September, they released a three-minute short of Ghost in the Shell characters using Surfaces. Chances are that they'll be making more of these types of ads in the future.
I, for one, was disappointed that the character wasn't named Inora the Explorer, but hey, you can't win 'em all, I guess...
