Kuroinu: Chapter 1 - The Dark Elf Queen, Loyal Subject, and Married Holy Knight

Kuroinu: Chapter 1 - The Dark Elf Queen, Loyal Subject, and Married Holy Knight is the first of three visual novels which together form a "director's cut" version of the Japanese adult fantasy visual novel Kuroinu: Kedakaki Seijo wa Hakudaku ni Somaru. Like the original game, Kuroinu: Chapter 1 has a focus on strong sexual content with an emphasis on non-consensual sex, degradation, and corruption. It features voice acting for female characters only.

The game takes place in the fantasy lands of Eos, located in the west of the continent of Serenus. A war raged between the Alliance, which consisted of both human and elven forces, and the Legion led by the dark elves. To end the war, the leaders of the Alliance hired a group of mercenaries known as the Black Dogs led by a gifted strategist named Vult to invade the Legion's territories and cripple them from within. The Black Dogs did as the Alliance requested, but rather than dismantle the Legion, Vult took control of their armies and turned them against the Alliance, betraying them. As the Alliance crumbled in the face of the Black Dogs' new power, Vult declared the founding of a new nation, aptly named the "Cuntry", where all women would be obligated to satisfy the sexual needs of the male citizens, especially Vult and his army.

The player controls Vult, a despicable man with a penchant for raping the women of the lands he has conquered. Chapter 1 features three heroines whose stories can be explored: the former dark elf queen Olga Discordia, her first knight Chloe, and a married human knight from the Alliance named Claudia Levantine. As prisoners of Vult, their lives are in his hands, and it is up to the player to determine their fates and the outcome of the story.
