About The Demon King: Harem

The Demon King: Harem places you in a fantasy world where you inhabit the Demon King’s body and manage his daily duties. A goblin queen reports a human empire attack, launching a quest that expands into rescues, alliances, and confrontations with various villains.

The game blends RPG storytelling with city‑building, letting you reconstruct locations that generate taxes. It runs as a single‑player title on Windows and lists DualShock, DualSense, and partial controller support, as well as Steam Cloud and Family Sharing features.

01 / THE GUIDE

Story Background

The protagonist is unexpectedly transported to a fantasy world, taking over the Demon King’s body and daily affairs. The Goblin Queen reports that her tribe has been attacked by the human empire, prompting the player to investigate and repel the invaders.

This inciting event leads to multiple objectives: rescuing a royal family, befriending harpies, helping trapped adventure sisters, and confronting a seductive witch. The narrative is described as having multiple character storylines that unfold as the adventure progresses.

  • Compare the Goblin Queen’s report with later events to spot narrative clues.
  • Observe how each rescued group expands the world’s context.

Romantic Characters

A range of romantic characters appear in the game, including a Succubus Maid, Goblin Queen, Female Officer, Harpy Harp Chieftain, Human Queen, Swordswoman, Nun, Elf Prophet, and Witch. Each is listed with a title that suggests a role in the storyline.

These characters are described as part of the adventure’s interpersonal elements, and some are tied to exclusive storylines or locations such as the Massage Parlor or tavern, indicating they can be interacted with during gameplay.

  • Note the titles to anticipate each character’s role in dialogues.

City Reconstruction

Players can rebuild several building types: Tavern, Clothing Shop, Item Shop, Church, and Massage Parlor. Each rebuilt building automatically generates taxes, with the total increasing as more structures are added.

Certain buildings also unlock exclusive storylines or characters, linking reconstruction to narrative progression. The tax generation is described as accumulating with the number of buildings, providing a measurable benefit to expansion.

  • Prioritize buildings that unlock exclusive characters for richer interactions.
  • Monitor tax growth as you add more structures to gauge economic impact.

04 / THE GUIDE

Controller Support

The feature list includes DualShock Controller Support, DualSense Controller Support, and Partial Controller Support. This indicates compatibility with PlayStation‑style controllers on the Windows platform during the single‑player experience.

Partial Controller Support suggests that some functions may still require alternative input methods, though the exact scope is not detailed. Players can therefore expect basic gamepad operation but should be prepared for occasional keyboard use.

  • Test both DualShock and DualSense controllers to see which feels more comfortable.
  • Check the partial support note for any functions that may require alternative input.

05 / THE GUIDE

Steam Cloud

Steam Cloud is listed among the game’s features, meaning that game data can be stored online through Steam’s service. This allows progress to be associated with the player’s Steam account.

While the description does not guarantee restoration after reinstalling, the presence of Steam Cloud suggests that players can check sync status after major milestones to confirm that data is being uploaded.

  • Verify cloud sync after major milestones to ensure data is being saved.
  • Use the same Steam account on multiple PCs to continue where you left off.
