What is Mythos: Book One?
Mythos: Book One is an adult visual novel developed by Nine of Swords that blends supernatural mystery, comedy, and romance into a single interactive experience. Version 1.0.0.0 delivers a complete first chapter where players step into the role of a protagonist—customizable as either male or female—who is thrust into the investigation of their ex-girlfriend Lisa Harrison’s enigmatic death. What begins as a personal tragedy quickly spirals into the discovery of a hidden society of supernatural beings living alongside humans. Some of these creatures mirror ancient legends, while others defy expectations with surprising twists.
The game stands out by offering meaningful choice-driven storytelling. Every decision shapes not only the unfolding investigation but also the romantic and sexual relationships the protagonist forms. Whether you pursue monogamous bonds, build a harem, explore lesbian dynamics, or choose abstinence, the narrative adapts organically. Adult scenes are never gratuitous; they emerge naturally from the paths you select and the bonds you nurture.
Story and Characters in Mythos: Book One
The central mystery revolves around Lisa Harrison’s disappearance, an event that pulls the protagonist into a world where vampires, fae, werewolves, and other beings coexist with ordinary humans. Some supernatural characters remain faithful to folklore, displaying classic strengths and weaknesses, while others subvert expectations with modern personalities and hidden agendas. This contrast fuels both comedic moments and genuine tension.
Characters are richly written and offer varied interaction styles. You’ll encounter beings who are flirtatious, aloof, protective, or outright dangerous. The protagonist’s gender choice opens distinct dialogue branches and relationship opportunities, including interracial pairings and same-sex female routes. Relational depth is emphasized: conversations, shared secrets, and joint investigations determine whether a character becomes a casual lover, a committed partner, or remains an ally without intimacy.
Key Relationship Paths
- Monogamous romance with deep emotional payoff
- Harem-style connections with multiple supernatural partners
- Lesbian and bisexual female-protagonist routes
- Platonic or abstinent alliances focused purely on the mystery
Each path influences the story’s tone, the clues uncovered, and the final resolution of the Lisa Harrison case.
Gameplay Mechanics and Adult Content
Mythos: Book One uses a classic visual-novel framework with branching dialogue trees and multiple endings. Player choices are tracked across chapters, affecting reputation with different supernatural factions and the availability of certain intimate scenes. The investigation elements require careful attention to dialogue options; missing a key conversation can lock entire routes or change the identity of suspects.
Adult scenes are varied and plot-relevant. They include:
- Detailed vaginal and oral encounters
- Creampie sequences with appropriate characters
- First-time intimacy with virgin supernatural partners
- Lesbian scenes between female protagonist and female creatures
These moments adapt to the chosen relationship style. A reserved protagonist experiences more tender, emotionally charged scenes, while bolder playthroughs unlock more explicit and varied encounters. All adult content is fully voiced and animated with smooth transitions that maintain the game’s signature blend of humor and mystery.
Visuals, Production Quality, and Technical Details

Character sprites convey distinct personalities through expressive facial animations and multiple outfit variations. Backgrounds mix everyday city locations with hidden supernatural locales, creating a believable dual world. Lighting and particle effects enhance magical moments without sacrificing performance.
The soundtrack complements the tone perfectly, shifting from lighthearted jazz-infused tracks during comedic beats to suspenseful ambient scores during investigative sequences. Voice acting is present for all major characters, adding immersion to both dialogue and intimate scenes. Version 1.0.0.0 is fully patched, stable, and includes an in-game gallery that unlocks completed scenes for replay.
