To be honest I can't say much positive things about it. Other than the fact that the original song is pretty much irrecognisable in this version of Neko Mimi Mode, the whole concepts is kind of... let me put it this way:
Let's say a moe denpa song is a cute, innocent 9 year-old girl. In that case, making an extreme metal version of this song would be like a tentacle monster deflowering said cute, innocent 9 year old girl. Now, while I am guilty of being a not4chan regular, I am not a particulary big fan of tentacles. Having a music representation of this is not within my taste.
Since when is Neko Mimi Mode considered denpa, though?
