'Urotsukidoji' - Legend of The Overfiend' (1989) aka Chôjin densetsu Urotsukidôji – Hideki Takayama.

I can still vividly recall the very first time I saw, Takayama's deliriously devilish, dayglow demented, fiendishly fabulous flesh flayer on my then greatly prized Big Box Manga VHS. This preternaturally perverse, polymorphously weird, wickedly warped anime masterpiece proved to be quite the mesmerisingly malevolent melon twister!!! The splatter-headed, dementedly demon-seeded 'Urotsukidoji' - Legend of The Overfiend' did much to pervert many impressionable young minds, Hideki Takayama's gloriously unfiltered phantasmagoria demonstratively galvanizing my own rabid interest in extreme Asian cinema/manga!!!
