The source is actually in the meta data of the webm, "[Doki] No. 6 - 01v2 (1280x720 h264 BD AAC)"
But I don't trust that and think it's actually Blue Submarine No. 6.
But actually, I put it through whatanime.ga and got Towa no Quon, what a journey.

This is the actual source, by the way.
Whoever made that webm is possibly a dick.
