The Fallen Prince’s Pleasure Dungeon: I Won’t Let the Female Adventurers Leave ~ I Was Reincarnated as the Villain in an Eroge, and Even Though I Just Want to Live a Quiet Slow Life, Beautiful Girls Keep Gathering Around Me!?~ - 1

Chapter 1: That’s basically a Medusa!

ーーーーーーーーーーーーーーーーーーーー

“Hiss.”

“That’s basically Medusa!”

Forgive the suddenness. This was the deep layer of a certain dungeon. Because a snake-girl monster was standing right in front of me, I couldn’t help but let out a retort in fake Kansai dialect.

(That person… is me. My name is Alto Raymond, a former prince.)

To go even further back, in my previous life, I was a salaryman working in Japan. The company I unknowingly joined turned out to be a nightmare, and naturally, a “black” work environment awaited me. To make matters worse, while I was working on a holiday—Labor Thanksgiving Day, of all things—I collapsed from overwork and said “sayonara-bye-bye” to that life.

And so… When I reincarnated, I was the third prince of a small kingdom. I was sixteen at the time. Quite handsome, too. Based on the information around me, I realized it immediately.

(Is this “The Fallen Prince’s Pleasure Dungeon”…?!)

It was an indie game I had played during the brief moments of respite from my black company life. Incidentally, it was R-18. The kind of naughty game only adults could enjoy. The situation proceeded exactly according to the scenario. There were many good-for-nothing types among the brothers of the Raymond royal family, and ugly power struggles were a daily occurrence. Having just reincarnated, I was caught up in it—

Not only was I kicked out of the royal family, but my life was targeted as well. With physical strength and magical power that weren’t much to speak of, I—Alto—had no choice but to run.

…That life as a fugitive was a literal hell.

I had to flee while avoiding public notice, and I was pursued not only by assassins sent by my brothers but also by wild dogs, bears, and even monsters. If things went well, I could only obtain decent food once every three days.

That kind of life continued for two whole years…! Even though I had finally reincarnated into a game world, I spent two years on a scenario that was supposed to be nothing more than a prologue…! I didn’t need this kind of realism! Literal hell!!

And so… After nearly dying many times, and when I was finally pushed to the very brink of death, I arrived here—at a cave-like dungeon.

As if invited by something, I crawled along the ground into the cave. There, my strength failed me. But immediately afterward, the evil miasma overflowing in the dungeon enveloped my body, and I transformed into a demon.

The wounds I had sustained during my life as a fugitive were completely healed. My disheveled, overgrown hair turned white, my eyes became red, and my entire body, now brimming with high-concentration mana, took on dark skin. The monsters knelt before me as I stood up, and I could even change the structure of the labyrinth with a single flick of my finger.

Yes. I had become the master of this dungeon. The first thing I thought after becoming the Dungeon Master—or rather, the words I bellowed:

“Dungeons are the best!!!!!!”

The gathered monsters really jumped at my sudden scream… But I couldn’t help it. For me, having grown to hate people during my two years as a fugitive, this space with not a single human in it was paradise. I hadn’t liked socializing since my previous life, and even back then, I would have preferred working from home forever if possible. (Though my company was “black,” so they forced us to come in no matter what…)

While many of the monsters were creepy, they prepared meals for me, and if I ordered them to, they would leave me alone. Unreasonably strict seniors, irresponsible bosses, brothers who thought of nothing but conspiracies… none of them were here. I swore to protect this life.

That was just a short while ago… or rather, it was the day before yesterday.

“Hiss.”

“Oh, sorry, sorry.”

While I was lost in thought, the Medusa girl in front of me grabbed my sleeve as if to say, “Pay attention to me.”

A Medusa in this world was a monster with an appearance that combined a snake and a human woman. The lower body was a giant serpent, while from the waist up, she was a semi-nude woman.

Her most distinctive features were her hair, which consisted of many snakes, and her golden, glowing eyes. She was exactly the “Medusa” I had imagined from my previous life. However, the snakes on her head were pink, giving her a somewhat stylized and charming atmosphere. Her cheeks even looked soft and squishy. Perhaps she was a bit young for a Medusa?

If you are glared at by a Medusa’s golden eyes, you turn to stone—but as the Dungeon Master, I was perfectly fine. Apparently, this Medusa found that delightful.

“Hiss, hiss.”

She showed her fangs and rejoiced.

“Yeah, yeah. Calm down a bit.”

This monster girl was short. When I patted the heads of the snakes, which sat at just the right height for me, she narrowed her eyes in pleasure.

“Hiss… ♪”

Rather than a snake, it felt like I was dealing with a cat—or a kitten. But it seemed that this Medusa was usually avoided by the other monsters. She had actually been surprised and frightened by me when I approached her without hesitation. Well, her appearance was quite intimidating, after all. I didn’t mind it that much, but it seemed even the monsters living in this deep layer were too scared to get close.

(Appearance, huh…)

“That’s right, can I do it if I’m the Dungeon Master?”

After thinking for a moment, I said aloud:

“《Character Creation》.”

When I did, a semi-transparent window floated in mid-air.

“Oh, it appeared!”

This was a function of the game. A feature that allowed you to change a character’s appearance.

“The question is whether it applies to monsters too.”

Originally, it was used to change the appearance of female adventurers who visited the dungeon.

(…Because it’s an eroge, right? You arrange the defaults and change them to an appearance that hits your fetishes.)

(By the way, female adventurers who lose in the dungeon end up having this and that done to them by monsters or by Alto the Dungeon Master—and the player enjoys various situational play. That is what “The Fallen Prince’s Pleasure Dungeon” is all about.)

The “Character Creation” was a flavor element of that. You could change hairstyles, body types, and even clothing.

“Let’s see… Can I try it on you?”

“Hiss?”

“Do you want to look like a human—or rather, like someone of the same race as me?”

“Hiss ♪”

The Medusa girl hopped up and down with her snake tail in joy. The idea of being “the same as me” seemed to strike a chord with her.

“Alright, let’s try it.”

When I held up my index finger, a giant, also semi-transparent “cursor” appeared. I swiped it and aligned it with the Medusa girl.

Ding!

“It worked! Character Creation is good to go!”

“Hiss ♪”

First, the lower body. The snake tail became human legs. Her skin, which was blue overall, became smooth, fresh white skin.

“Ugh… I—I’ll try not to look as much as possible, okay?”

“Hiss?”

This girl was currently stark naked. Her waist, her stomach, and her jiggling breasts. Not just her legs, but her lower abdomen was also that of a smooth human.

(That’s right, this was originally an R-18 game.)

I had no impure intentions, but I averted my eyes. I couldn’t look directly! Because a game and a living body are different…! I was a corporate slave, so I’m a virgin…! (An excuse).

“Ahem.”

The next Character Creation was the face. I kept her charming golden eyes as they were. However, I made her sharp eyes gentle and soft. Yet, I left a light that seemed full of curiosity. It wasn’t so much my preference as it was giving form to the image I had of her.

One more thing: the snakes that were her most prominent feature. I’m sorry, but I had the intimidating snakes “log out” and replaced them with a fluffy short-cut that mimicked the silhouette. The hair color was pink. She turned into quite the beautiful “busty loli” girl.

“Alright, it’s fin—Wait, no!!!”

“?!?”

The Medusa girl jumped at my sudden shout.

“The angle of the eyes is still… no, is it the size of the nostrils? The angle of the eyebrows? Hmmm.”

“?”

Character Creation was a swamp. Once you started, even the slightest difference in facial parts started to bother you.

“The chin? The position of the ears… no, no, no!”

(Aaaah, the more I do it, the deeper I sink!! Changing and fixing, changing and fixing…!)

“Not yet, I haven’t quite captured this girl’s image yet! More like this, fluffy, but with a bubbly feel to it too…!”

“Hiss.”

“Sorry for making you stay with me. But I’ll definitely express the absolute best version of you!”

“Hiss ♪”

(Alright, let’s do this. I’ll do it, a perfect Character Creation…!)

Five Hours Later…

“Huff, huff…!! Th-this is it…!”

“Hiss.”

Standing there was a perfect Medusa girl (Human Ver.)! The ultimate Character Creation that reproduced this girl’s personality 100%! She was a head shorter than me and looked young, but since this was the world of an R-18 game, this girl was also eighteen or older. She had an innocent look and cheeks that looked soft to the touch. The modest fangs peeking out when she smiled were adorable. The smooth curves from her neckline to her shoulders and chest. And the breathtaking bust. They were so ripe you could almost hear the sound effect “boing,” and with a youthfulness that defied gravity, her pink nipples were pointed sharply.

Her stomach looked soft but she had a waist, and her hips, which looked like they would grow into a child-bearing type in the future, were also attractive. A smooth, hairless groin. This part was modeled entirely by relying on skills due to my lack of experience—but within the healthy skin, a faintly pink-tinted slit could be seen peeking out. Her thighs were plump and made me want to be squeezed by them, and both her beautiful legs were flawless down to her toes.

“How is it…!”

“Hiss ♪”

Sensing that I was happy, the Medusa girl (Human Ver.) hugged me.

“Y-you’re naked…!”

The “Evil Dungeon Master”—that was, me—stiffened up completely after being hugged by a beautiful girl around eighteen years old. I was aware there was a “Monster girls should stay monsters!” faction out there, and that they boasted a powerful influence. In fact, I could understand that fetish too.

(But I’m a “Beautiful girls are better, after all!” person!)

This beautiful girl, who was innocent yet drifted with the mysterious atmosphere of a Medusa, was so cute I couldn’t help myself!

“M-Ma… ster…”

“!?!”

(I see, it’s because she now has human vocal cords.)

“Master… love…!”

The Medusa girl (Human Ver.) rubbed against me.

“It’ll be hard to call you that. How about ‘Medi’?”

“Me… di?”

“It’s a name. I’m Alto, and you’re Medi. How’s that?”

“…………!”

Medi suddenly pulled away from me, her golden eyes sparkling.

“Medi… Master, Alto…! Together!”

“That’s right. Together.”

When I patted her head like I did before:

“~~~~~♪ Together, together.”

(What a great smile. She really is different from filthy humans.)

“Phew, I’m exhausted as expected. Should I hit some energy drinks?”

“…E-ner-dy?”

“Yeah, this.”

I pulled a small bottle out of thin air. Inside was a thick green liquid.

“That’s … A recovery, potion, I think.”

“It’s fine. To me, it’s an energy drink.”

“Energy drink… yummy?”

I shook my head at Medi’s question.

“It’s not about whether it’s yummy or not. An energy drink is an energy drink.”

“?”

“Do you want to drink it too, Medi?”

“Medi, drink…!”

I pulled out another bottle, and the two of us stood with our hands on our hips and gulped down the small bottles.

“Puh-haaaa!”

“Puh-haaa!”

The fatigue from character creation was completely recovered!

(This is the one! Dungeons and energy drinks really are the best!!)
