「正しいヒロインの躾け方〜突然手に入れた“黒魔術”で世界征服を目論む〜」continues its harem dark fantasy premise with a protagonist who has already bent his childhood friend to his will using dark magic, and who now turns that power toward the wider world. The story follows him as he takes up adventuring alongside her, using his dark magic to fight monsters while keeping her bound through contract magic in their day-to-day life.

The central event of this stretch of the story is a mission to hunt down orcs that have taken a princess knight captive. The protagonist and his companion are called up for the operation, and the trail leads them into the orcs' dungeon stronghold, where the captive knight has been subjected to control through contract magic and to abuse at the hands of the monsters holding her.

Readers drawn to this series are likely those who want their fantasy conquest stories unflinching rather than softened, with the protagonist's dominance over the people around him treated as the core engine of the plot rather than something to be undone. The dungeon raid gives the story a clearer adventuring backdrop than simple domestic control, placing the characters in direct physical danger while keeping the same power dynamics running underneath.

The captive princess knight's situation adds a darker edge to the conquest narrative, raising the question of what becomes of her once the protagonist and his companion reach her. Fans of harem dark fantasy who want corruption and domination handled directly, without being swapped out for a gentler romance, will find that tone carried through this stretch of the story.

Overall, this entry keeps the series' established formula intact: a protagonist who treats both monsters and people as targets of his growing power, a loyal companion already remade by his magic, and a new captive whose fate is tied directly to the dungeon's outcome.
