This is an odd SERP from Bing. The chances are high that this is a glitch and not the result the engineers would want to show.
We see that there are results for the [Attack on Titan] search. None of the results are found on webpages, though. At least that's the interpretation of the categories applied here by the search. Matches are restricted to either images or videos.
We can safely conclude this is a glitch because the rich media results are good for the search. That's what I'd expect to see. Furthermore, Bing clearly knows a lot about the search as it provides related search terms which are pretty much appropriate too.
