What does this remind you of?
 

It made me think strongly of Pandora Hearts, but I don't think that's it.

You're probably thinking of Elfen Lied.

I've never seen that one.

If that's what you were looking for.

Otherwise, if your thread is an actual topic, then it didn't remind me of anything because of all the random pictures getting in the way.

Wow yeah, that does explain where it came from. I was partially wanting to figure that out, and partially curious what others would think of after reading one of the comments on the actual youtube page.

Maybe because Yuki Kajiura composed the OST for both Noir and Pandora Hearts o:

Oh dang, I didn't know that. Yeah, that's very possible why I thought of Pandora Hearts so strongly.
