Sword of Ryonasis (full title: Sword of Ryonasis ~Kirsch in Lewd Labyrinth~) is a 2D side-scrolling action game that leans heavily into the "ryona" and "eroge" subgenres. Developed on an older engine, it features a new knight named Kirsch who ventures into a suspicious cave to find her missing friends. Gameplay Mechanics
Combat: Kirsch primarily uses a broadsword with exceptional reach for massive swings. She also has access to a fireball spell for ranged combat, which consumes mana from a limited magic meter.
Progression: As players defeat enemies, they earn experience points to increase health, speed up mana regeneration, and learn new techniques.
Exploration: While side-scrolling, the game is non-linear and features an overworld that reveals the depth of the cave descent.
Difficulty & Replayability: The game is generally considered easy and short, typically taking between 1 to 2 hours to complete. It lacks a hard mode, which limits its replay value. Visuals and Audio
Art Style: The character designs are described as "thicc," focusing on high-quality artwork for Kirsch and certain bosses. However, some reviewers find the backgrounds to be uninspired or "flash game quality".
Sound: The music is considered decent but suffers from noticeable low-end bass issues. Some assets and sound effects are noted as generic or royalty-free. Content and Theme
Eroge Elements: The game includes 18 unique CGs and various erotic productions. Notably, it features a "Glo Filter" (default OFF) for players who want to avoid more extreme "guro" content.
Language: The game is currently available in Japanese, though it remains playable for non-speakers due to its straightforward action mechanics. Technical Pros & Cons Well-drawn character art
No native fullscreen support (requires external software like Lossless Scaling) Functional combat with both melee and magic Very short duration (under 2 hours) Includes comfort settings like "Glo Filters" Clunky gameplay and unpolished level design
Verdict: According to reviewers from 336GameReviews, the game is a fun experience for fans of the ryona genre but lacks the depth and technical polish for a broader audience. Critics on Steam Community suggest it is a "hard pass" unless found at a significant discount. Lapinoire :: Games - Steam Community

, a knight who ventures into a near-mythical cave where an evil god is rumored to dwell. Historically, elite soldiers entered this labyrinth and never returned, leading many to dismiss the danger as mere folklore.

2. The Apostate Knight, Valdrik Mal’Tor
The most infamous wielder was Valdrik Mal’Tor, a templar who broke his vows to the Solar Orthodoxy. Valdrik stole the Sword of Ryonasis from the Shrine of Hanging Tears after witnessing his king sacrifice children to prolong a drought. Enraged, Valdrik used the sword to cut the concept of kingship out of the royal bloodline. The entire dynasty instantly forgot how to rule, speak, or even stand upright. They devolved into feral, mute creatures within a week. Valdrik’s tragedy? The sword’s backlash erased his memory of why he was angry, leaving him a pacifistic wanderer who wept at the sight of sharp objects.
Properties & Abilities
The Sword of Ryonasis is a Ruin of Justice—a lawful-aligned artifact that despises deception and broken vows. It cannot be wielded for personal gain, assassination, or war. If drawn in anger or for unjust killing, it becomes as heavy as a sundered oath and cannot be lifted.
1. Sever the False (Always Active)
The blade cuts through illusions, glamours, and shape-shifted forms as if they were cobwebs. A creature struck by the flat of the blade (non-lethal) is forced to revert to its true form and cannot lie verbally for one hour.
2. Unmake the Oath (Once per day)
The wielder may point the sword at a visible contract, magical binding, or sworn vow and speak the word “Ryonasis.” The blade emits a low, sorrowful hum. The target oath is severed as if it never existed. This destroys the document, dispels the geas, or frees a creature from a devil’s pact. The wielder suffers one level of exhaustion as a cost.
3. Echo of Regret (When unsheathing)
The first time the sword is drawn in a scene, all creatures within 30 feet who have broken a significant oath in the past year must make a Wisdom saving throw (DC 17). On a failure, they are Stricken with Guilt: they suffer disadvantage on attack rolls and ability checks for 1 minute as they hear the ghostly whispers of those they betrayed.
4. Cannot Draw Blood
The blade passes through living flesh without leaving a mark. It does no physical damage. It can damage undead, constructs, and creatures composed of pure magic or falsehood (e.g., a mimic, a illusion wizard’s projected self).
Powers and Abilities
The powers attributed to the Sword of Ryonasis are as impressive as they are varied. It is said to possess the ability to vanquish any darkness, making it a weapon of choice for heroes and warriors on a quest to defeat evil. The sword is also believed to grant wisdom and clarity to its wielder, allowing for strategic brilliance in times of conflict. Some legends suggest that the sword can channel the elements, summoning wind, fire, or water to aid its wielder in combat.
