Babymetal. I assume a Japanese metal band. Imagine a mix of vocaloid, speed metal, and thrash metal. There's just such a dissonance between the happy female vocals and the heavy brootal guitar riffs and face melting tapping solos that it's just what is this i dont even.
What's more crazy is their music videos. I have no idea what is happening.
Well it's obvious what's happening to me. This Japanese schoolgirl is mourning the loss of a loved one who happened to be the lead of a heavy metal girlband when all of a sudden Lilith took favor upon the girl and gave her a neckbrace filled with powers akin to the serpentine necklace of the maiden Harmonia that the mute Isaac stole for her when Lilith chose the nun Victoria to be her avatar in the Dark Ages, a decision which lead to the beginnings of true corruption and decadence within the Vatican and the Catholic church due to Lilith's decision to make sure that even the Pope knelt before a woman of power. Lilith favors the schoolgirl because her loss reminds Adam's first wife, the mother of the lilim, the betrothed of the angel of death Samael and the mother of the patron saint of witches and heretics the goat-headed hermaphrodite Baphomet, of how her first love Cain, the biblical brother-killer who God cursed to become the world's first vampire, spurned her advances and betrayed her after she had taught him the secrets of both Heaven and Hell that she learned after divorcing herself from Adam due to her spurning of his bumpkin ideas of courtship and patriarchy which dictate that woman must serve under man. This leads to the girl becoming an adorable advocate for darkness and the base hedonistic nature of humanity as she decides to spurn what society dictates to be her responsibilities and instead chooses to live life to it's fullest as an agent of the Dark Mother herself. She manages to in the process gain powers of summoning and brings her friend back from the abyss so that she may use her power to become a herald of Gehenna and the end of days.
Or you know, it's just Japan being Japan. They brought us Hello Kitty AK-47s, vending machines that dispense panties, and the inspiration for 4chan. Babymetal is pretty vanilla for them.
