Byleth: The Demon of Incest1972
“A boy is blinded with incestuous passion.”
Directed by Leopoldo Savona
The premise
A young man becomes obsessed with Byleth, the demon of incest, and it leads to an unhealthy infatuation with his sister.
Horror Vault's take
In this darkly charged Italian horror relic, a nobleman finds his mind and desires increasingly warped by the influence of Byleth, a demon with a particularly sinister dominion. What begins as a simmering psychological unease slowly poisons his family bonds and erupts into violence and scandal. The film leans into Gothic atmosphere and transgressive subject matter to craft a tale of corruption from within. Fans of early-70s European horror will find a genuinely provocative curio here.
