Yesterday I found it on a peertube instance. And found it amusing enough to share.

After the initial excitement and an hour of searching, I located the source, assumed the reason, and tried to contact the author.

This guy, at the time of making this video (2014), played a Swedish game about WW2, Hearts of Iron 2: Doomsday Armageddon and was a fan of Idol M@ster anime. He combined two of his passions in a very interesting mix.
He states in the description that the translation to Japanese may not be absolutely correct as he translated it from English. And creeping lines are just his comments with some random noise.
Also, other videos with this song.
Melody is very inspiring, one can pass any agitating text with it.
