Hello everyone! Today, I’d like to introduce “NTR Erotrap Dungeon ~Until Sword Saint Elisa Falls~” (NTRエロトラップダンジョン〜剣聖エリザが堕ちるまで〜), a lighthearted and entertaining NTR adult RPG developed by circle “Munenick Alpha” (むねにっくあるふぁ) and sold on DLsite for 1,980 JPY. Currently, the game only supports Japanese and features no voice acting. In this game, players get to watch a cool and powerful heroine gradually succumb to carnal pleasure. With zero violence or sadism, the story maintains a light and upbeat mood throughout. If you like the heroine’s design or enjoy watching a strong girl get addicted to fleshly desires, I highly recommend giving this title a try!

2. Story & Background: The NTR Tale of a Beautiful Sword Saint and Her Perverted Subordinate
The heroine, Elisa, is the kingdom’s top Sword Saint. Not only does she possess top-tier combat skills and a strong sense of justice, but she also boasts peerless beauty and a jaw-dropping figure. She appears to have a fiancé, and her biggest weakness is her breasts.
You play as Elisa’s subordinate—an ordinary guy with no grand ambitions who just wants to idle away his days. Consequently, you often get scolded by Elisa, though you don’t seem to care at all and love sexually harassing her whenever you get the chance.

One day, while you and Elisa are out on a routine mission, you are suddenly summoned by the Kingdom’s Corps Commander. Expecting that you’ve caused trouble again, Elisa nags you all the way to the commander’s office. Upon arrival, however, she discovers it isn’t about trouble at all—Elisa’s strength and achievements have been recognized by higher-ups, who have decided to promote her as the kingdom’s very first female Division Commander. Elisa is thrilled, as her ultimate goal is to reach the top ranks and reform the decaying kingdom.
Here comes the catch: if Elisa is being promoted, why summon a low-ranking subordinate like you as well? It turns out her promotion comes with a strict condition: “Clear a designated dungeon without any equipment while bringing along one subordinate.” The condition is meant to prove that Elisa can protect a weak companion and overcome hardship in any situation. Although Elisa is thoroughly annoyed at having to bring a useless, perverted subordinate like you, she accepts the condition for the sake of her ambition.
After confiscating Elisa’s gear, the Corps Commander places no special restrictions on you and even thoughtfully hands you a set of equipment to put on. But once you gear up, you realize something is off—these items are way too “overpowered,” far beyond anything a low-level soldier like you should ever lay hands on.
The heroine acts a bit strange after being out of sight for just a moment…?
That’s right—Elisa’s promotion is merely a guise, and the true plot resides within that mysterious “dungeon”…
3. Game Objective: Conquer the Terrifying Dungeon Where Orgasms Weaken You
The goal is straightforward: guide the protagonist and Elisa through the designated dungeon. Naturally, this is no ordinary labyrinth—it is packed with all kinds of monsters, traps, and a core, lethal mechanic: whenever a female reaches climax inside the dungeon, her physical attributes degrade and her level drops. How will Elisa, the kingdom’s strongest beautiful Sword Saint, brave these trials without her gear? And what role do you, the useless subordinate clad in top-tier gear, play in this conspiracy?

Everything will be revealed once you reach the ending.
4. Game Loop: Gathering Materials, Fighting Monsters, and Erotic Traps
The gameplay loop is simple. Each cycle is divided into three phases: Pre-exploration, Dungeon Exploration, and Post-exploration. Pre- and post-exploration offer similar options, with the post-exploration phase adding a dining segment. The main focus remains on clearing the dungeon itself. The dungeon spans six floors, each with different enemies and traps, but the core objective remains constant: gather key items and reach the exit.

Clearing all six floors while satisfying specific conditions will trigger the ending sequence.
5. Interface & Core Mechanics: System Overview
The mechanics are easy to grasp. I’ll break them down into four main parts: Base Overview, Status Screen, Dungeon System, and H-Scenes.
Base Overview
First is the Base, where you spend time before and after daily dungeon runs. Despite being called a base, there aren’t many facilities. The top right features a cooking area, though regular food provides no buffs. Only a special menu item, “Memorable Gratin” (思い出のグラタン), unlocks a hidden feature, which will be detailed in the walkthrough section.
The bed at the bottom right is used to skip to the next day, which has little practical value.
The merchant on the left sells only three items: Potion (ポーション), Refresh Potion (リフレッシュポーション), and Hypnosis Pendant (Strong) (催眠ペンダント(強)). They recover HP, lower Arousal (発情度), and enhance hypnosis functions respectively.
The top left leads to the Punishment Room. If you lose in the dungeon, Elisa will be sent here for punishment. This room can be accessed freely later in the game.
Status Screen
This menu lets you inspect the heroine’s current status and execute special commands. It unlocks after completing Floor 1 and can be accessed by clicking on Elisa’s sprite or dialogue.

There are only two stats you really need to keep an eye on: 1. Level 2. Arousal (発情度).
A lower level makes dungeon exploration significantly harder. Arousal works similarly—the higher it is, the more damage she receives in combat. You can lower it using items or by triggering climaxes, though given the game’s low difficulty, you don’t need to stress over these numbers too much.
Arousal also dictates whether you can initiate intimacy or hypnosis with Elisa; if it’s too low, she may refuse your advances.
As for Dependency (依存度), I haven’t found any noticeable effect on gameplay, so you can safely ignore it.
On the right side, there are six commands: Chat (雑談), Hypnosis (催眠), Fellatio (フェラ), Sex (えっち), Climax Light (アクメライト), and Outfit Change (おきかえ). All functions unlock automatically with story progression. Here is a brief overview:
| Option / Function | Description |
|---|---|
| Chat (雑談) | Talk with the heroine. Dialogue changes according to story progress or Arousal level. |
| Hypnosis (催眠) | Engage in hypnosis play with the heroine. |
| Fellatio (フェラ) | Self-explanatory oral sex interaction. |
| Sex (えっち) | Features three types of sexual play, all unlocked after clearing Floor 6. |
| Climax Light (アクメライト) | A key item acquired during the story that instantly boosts Arousal. |
| Outfit Change (おきかえ) | Change the heroine’s outfit; unlocks automatically as the story progresses. |
Unfortunate that there are only three outfit choices
Dungeon Overview
Dungeon gameplay is very basic: search the map for two keys/crystals to open the door and reach the exit. While each floor features different traps and monsters, combat is resolved instantly by touching enemies on the map, consuming a bit of HP while eliminating the monster.
The core gimmick revolves around the curse: our invincible Sword Saint heroine loses 1 Level every time she reaches climax in the dungeon. As you progress, Elisa—who used to slay monsters effortlessly—will find combat increasingly grueling, and even her proud Sword Saint title will slowly demote.
The lower her level, the more damage she takes
Should she be defeated in the labyrinth, Elisa will be taken to the special Punishment Room to suffer “erotic punishments,” weakening her further. Naturally, there is a deliberate motive behind all of this…

H-Scenes
H-scenes in this game primarily feature simple Live2D animations alongside static CGs. Almost all H-scenes unlock naturally by progressing through the main story without complex requirements. Additionally, a full CG gallery unlocks automatically upon game completion, making it very user-friendly.
6. Walkthrough & Guide: Hidden Features and Ending Branches
Since the game lacks complex systems or demanding controls, the difficulty is fairly easy. You can play at a relaxed pace. Here, I’ll cover a few useful tips, hidden features, and ending branch requirements.
Playthrough Tips
Although the game is easy, I advise against lowering Elisa’s level to rock bottom early on just for fun. Doing so might leave her unable to defeat even a few enemies in later stages. While it won’t permanently brick your save, there’s no need to make things harder for yourself.
Items & Gold
As mentioned before, the shop sells three items: Potion, Refresh Potion, and Hypnosis Pendant (Strong). The first two are combat aids that you don’t really need to buy if you can clear floors smoothly. The third item adds a new hypnosis option and costs 5,000 Gold. Gold is earned by defeating monsters, so beat extra monsters while Elisa’s level is high early on to accumulate 5,000 Gold before she gets weakened.
Hidden Feature Guide
Earlier I mentioned cooking curry, which offers no special effects. However, there is a special dish called “Memorable Gratin” (思い出のグラタン) that acts as the key item to unlock a hidden feature.
During a night event, Elisa complains about eating curry every single day and mentions missing the gratin she used to eat with her fiancé. The next day, our shameless protagonist harasses her as usual, asking to grope her breasts. Elisa brushes him off, saying, “Fine, if you can make that gratin I mentioned yesterday, I’ll let you touch them.”
And thus, a life-risking deal is struck!
In short, gathering the ingredients and preparing the gratin unlocks a hidden touch interaction mode. The three required ingredients are hidden inside specific dungeon floors. Since you cannot re-enter cleared floors, make sure to collect the ingredients before moving to the next floor.
Here is a quick reference table for the three ingredients: Milk (牛乳), Premium Fish (高級魚), and Octopus (たこ).
| Ingredient | Floor | How to Obtain |
|---|---|---|
| Milk (牛乳) | Floor 1 | Obtained from the ranch in the center of the map |
| Premium Fish (高級魚) | Floor 2 | Defeat the “Fish-type monster” in the labyrinth |
| Octopus (たこ) | Floor 6 | Defeat the “Octopus-type monster” in the labyrinth |
Special monsters like this will hide in corners
Since the final ingredient is on Floor 6, the gratin can only be cooked after clearing Floor 6. Preparing it triggers a short event that unlocks the touch feature. Note that this is completely optional and not required to finish the game. As for whether the touch feature is worth the effort… I’ll leave that for you to find out!
Ending Timing & Conditions
After clearing all dungeon floors, you enter free mode. There are no mandatory tasks, and all facilities remain open. Theoretically, you should be able to trigger the ending at any time. However, during my playthrough, I couldn’t trigger the ending exit until I lowered Elisa’s level a bit further. If you get stuck after clearing Floor 6, try reducing her level slightly.
If conditions aren’t met, the game prompts you to keep breaking her
Ending Branches
There are two endings in total. The choice occurs right after exiting the dungeon, without complex prerequisites. The game auto-prompts a save right before the decision, so prior play choices don’t lock you out. Below is a brief summary of both routes with mild spoilers:
Option 1: “Go seek revenge on the Corps Commander” (軍団長に復讐に行く)
Having completely fallen to lust inside the dungeon, Elisa escapes only to find her body thoroughly awakened to pleasure, though her stats slowly begin to recover. Pushing away the protagonist who is still groping her, she storms into the Corps Commander’s office to settle the score.
Unfazed, the Corps Commander calmly tells her that leaving the dungeon was only possible because her mind and body had already surrendered to ecstasy. Pulling out his massive cock right in front of her, Elisa realizes in that instant her true identity, her future, and what she truly desires…
Option 2: “Live as a flesh toilet” (肉便器として生きていく)
Thoroughly broken by your training in the dungeon, Elisa loses all reason and willpower. Desiring nothing more than carnal pleasure from you, her master, she moves in with you to live as your personal sex slave.
Endless sex, climaxes, and pleasure—a simple yet decadent life. The once-mighty Sword Saint Elisa is now nothing more than your obedient pet.
You are her master for life
7. Final Thoughts: A Solid Quality NTR Nukige
What drew me to this title originally was the heroine’s archetype: a blonde, big-breasted, powerful, and beautiful Sword Saint. The in-game sprites and CGs deliver on that promise, showcasing wonderfully erotic artwork. While the total number of scenes isn’t massive, the developers did a great job highlighting her appeal.
The “you’ll pay for harassing me” expression is fantastic
Despite “NTR” in the title, the fiancé/cuckold elements are minimal and only briefly mentioned at the start and end. The primary focus is on the playful, perverted interactions and sex scenes between the protagonist and Elisa in the dungeon. Since the protagonist is a shameless rogue rather than a knight, he takes full advantage of her at every turn. The sequence where he tricks her into stepping on multiple erotic traps had me laughing out loud.
Very little screen time given to the fiancé
Using the heroine as a trap mine-sweeper
If there’s any drawback, it’s the lack of deeper gameplay systems. The setup could have supported more elaborate training or teasing mechanics, which the game doesn’t explore extensively. While the overall experience is smooth, it leaves you wanting a bit more right as things start heating up.
You can probably guess what play style this angle implies
Overall, “NTR Erotrap Dungeon ~Until Sword Saint Elisa Falls~”(NTRエロトラップダンジョン〜剣聖エリザが堕ちるまで〜) is a well-crafted NTR nukige. With no overly complex lore, players can comfortably enjoy beautiful CGs and the heroine’s corruptive downfall. Boasting strong sales and reviews on DLsite, it’s a solid recommendation for fans of the genre and character archetype!
