But what is the ? Is it the most well-produced? The most controversial? The one with the deepest plot?
La Blue Girl arrived during the "Western anime boom" when stores like Suncoast Video and Blockbuster would hide VHS tapes behind the curtain. It was many Westerners' first hentai. The plot is insane: Miko Mido is a shrine maiden from a long line of ninja sex-magicians who must battle demonic creatures called Shikima. Her primary weapon? Sex.
Bible Black succeeded where most hentai fails: it told a genuinely compelling horror story. The plot follows High School student Taki Minase, who discovers a forbidden grimoire that belonged to a witch burned at the stake 200 years prior. Using the book's magic, he can cast spells, but he awakens a demonic entity.
