Dragon Knight
Released in 1991. A hentai featuring girls getting gangraped by lizardmen and bugbears in a fantasy setting. And of course, the Sword of Light turns into another girl after the Dark Lord is vanquished. Might cause sanity damage to the weak-willed. At least there are no tentacle beasts.
Remember, demi-humans in hentai are required to gangrape humans at any given oppurtunity.
