Harem King

Well met, traveler.

I’m Yoguruto, and I’m proud to present the alpha version of Harem King.

Harem King is a medieval fantasy adult visual novel built in Ren’Py using Koikatsu, focused on character relationships, political pressure, and the quiet cost of authority.

The Premise

You play as Isaac, a man who deliberately chose a small, peaceful life in a chaotic world—working as a carpenter alongside his father, far removed from court politics, despite being the nephew of King Mikhail of Aurelion.

That peace ends abruptly.

With the king’s sudden death and no other viable heirs, the crown is forced upon you. A looming invasion from the Dark Territory leaves no time to grieve, no time to hesitate, and no margin for failure.

You must learn—slowly, imperfectly—how to rule.
How to stabilize a kingdom on the brink.
And how to navigate bonds, desire, and loyalty when fate ties more than one heart to yours.

This is not a power fantasy.
It’s a story about responsibility, consequence, and the fragile balance between duty and intimacy.

Characters (Alpha)

• Isaac – The reluctant king. Thrust into power far beyond his preparation, forced to grow or fracture under pressure.

• Anastasia – The queen by circumstance. Sharp-tongued, self-destructive, and far more perceptive than she lets on.

• Etsuko – The boisterous elder princess. Familiar, playful, and dangerously honest.

• Keiko – The younger princess. Gentle, devoted, and quietly resolute.

• Yuzuki – A gossiping kitsune who somehow became palace steward. She still treats you like a child—and knows far too much.

• Suzume – The former king’s concubine, chosen by tradition rather than love, and left behind in the wake of his death.

All characters depicted sexually in this game are adults.

Current Features (Alpha)

• Custom cinematic cutscenes

• Original Soundtrack

• Expansive world map (early implementation)

• Quest system

• H-scenes and animations

• Relationship paths and bond gallery (in progress)

• Affection system (in progress)

Expect placeholder assets, unfinished routes, and rough edges. Core systems and narrative foundations are in place, but content is not final.

Inspirations

This project is shaped by character-driven stories that prioritize consequence, restraint, and quiet emotional weight over spectacle.

Narrative touchstones include Attack on Titan (particularly its later arcs) and selective themes from Sword Art Online, especially around responsibility and survival within rigid systems.

Visual novel influences include Goddesses' Whim and Broken Dreams.

These works are points of reference—not promises of scope or scale.

Development Note

I’ll be stepping away for an extended period starting this summer. This alpha release is meant to gather feedback and set direction before that pause. Development will resume afterward.
