What is this Kawaii Metal?

I’ve seen lots of stuff I don’t understand but this particular video has me prisoner because I believe it signifies something of import. Yes, it is a mash-up of Death-Metal, Kawaii, millisecond edits, Jesus, teen-fetish, and intricate over-loaded hand gestures. It may play out as an ephemeral trans-cultural fad. However, I ponder why this artifact came to be.

Perhaps this simply a shallow global marketing effort akin to The Monkees.

Or perhaps it is evidence of something else? Indulge me in over-abstraction wherein a particular signal is selected. Could it be an eruption of latent Japanese pride, of long suppressed nationalism, saying “Hey Western World: Remember us? We were rebuilt in your image and likeness. We gave you Kanban, adoration of technology and sushi. Why have you forsaken us for China?” Japan has experienced a catastrophic housing bubble, outsourcing, and a dankai no setai generational welfare Rubicon. Japan is your future. Japan’s culture is asking us to pay attention.
