I will be a biologist!
“Captain, it’s mealtime. Are you going to feed me again?”
“Ah, it’s fine. Just leave it there.”
I’m happy to be fed by Alana. Because she feeds me with her mouth.
It’s tough being fed by Alana. Because her claws pierce my skin when she hugs me.
I’m in my usual spot. The man aiming to be the Pirate King seems to like sitting on the bow, but my usual spot seems to be being hung from the bow.
When Alana brought the food, she seemed to pity me, hanging there, and fed me by mouth from her own mouth.
When I asked her to pull me up, she refused, saying, “Sophia-nee-san is scary,” and Alana came down, holding food in her mouth, using the rope.
Of course, I was being given food for energy, but Alana, trying not to fall into the sea, dug her claws into me to maintain her balance.
As a result, the meal became bloody, and the dripping blood excited the piranha dolphins swimming on the surface, making them repeatedly jump at me.
When they jump high enough to breach the surface, they always swim sideways beforehand. I assume they’re checking what’s on the surface, but if you know that, it’s easy to avoid them. I learned that the hard way, getting bitten three times.
One practical experience is better than a thousand theories. By playing with the piranha dolphins, I was able to learn deeply about their ecology. Someday, I’ll travel the world and write a paper.
I’m not here because I wanted to study the ecology of piranha dolphins. I’m here because I’ve already learned about the ecology of mermaids.
After repelling the Kraken, I, of course, headed to Sophia’s room. The White Lily Corps know her ferocity and wouldn’t interfere. The very people who were supposed to help, the mermaids, interfered.
The mermaids rejoiced. Their sorrow from before had been lifted, so they expressed their joy with their whole bodies. I paid no mind to such things, and as I reached for the door to enter the ship, a fish-person grabbed my hand.
“Gyo gyo…”
Just like a fish, they cried “Gyo gyo.” That’s lame! Let go of my hand! A more terrifying opponent than the Kraken awaits me in the cabin!
The fish-person took my hand and started dancing. This was probably a dance of gratitude and joy, but I felt no emotion seeing a creature with legs and arms like a fish.
I only felt emotion when Sonya embraced me in her human form. Seeing that, the mermaids finally transformed from fish-people into human form. The sight is burned into my memory and unforgettable.
Fish don’t wear clothes. Even when they take human form, they don’t wear clothes. The sight of fully nude women dancing across the deck was somewhat bizarre, but my eyes were happy.
I suppressed my urge to dance with them, hold them, and push them down, trying to calm myself by talking to the captain about the broken ship.
The captain listened to me, but their eyes never met mine. They said they need to bring the ship closer to shore for repairs… Look at me!
We brought the ship closer to shore, and instead of immediate repairs, a celebration was held. It was apparently meant to be food for post-childbirth recovery, but the mermaid leader declared that nothing was more joyous than the Kraken’s demise, and the celebration began.
This is where the biological research finally began. I was very interested in the ecology of mermaids and asked them many things, such as why they didn’t wear clothes that would enhance their beauty.
According to them, the fish-like form is their true form, and the human form is a transformation. It was quite disappointing, but they had no custom of wearing clothes, and they only transformed into human form during childbirth or when coming ashore.
Also, and this is a very important biological point, there are no male mermaids. Mermaids are born hermaphroditic.
Observing them dancing naked, I noticed two types: those with breasts and lower bodies, and those with only breasts. They meet as hermaphrodites, and then decide their gender based on discussion and feeling.
For the mermaid who chooses the male role, their body remains the same, but if they choose the female role, their lower body disappears within about a month, corresponding to the growth of the abdomen.
As a man, it’s a nightmare, but for mermaids, it’s perfectly normal, and they even asked me why it wouldn’t disappear.
After giving birth, they raise their children with their lower bodies still gone for a year, and starting from the second year, their lower bodies gradually reappear, and they live as hermaphrodites.
There are also cases where both choose the female role upon meeting, in which case two hermaphrodites change their gender to two females.
I showed great interest in their peculiar ecology. Sonya willingly answered my questions, greatly contributing to my knowledge as a biologist.
Indeed, even in academics, fieldwork is essential for a biologist. You can gain firsthand knowledge that you can’t get from a desk.
I listened well, I saw well, I touched well, I licked well, I entered well, I moved my hips well, I ejaculated well, and I was shot and hung.
Danger is inherent in fieldwork. I believe that the weapon of knowledge will protect me. However, lasers are another matter…
My report as a biologist will be insufficient with just this alone. I want to convey the living voices from the scene.
“You’re making quite a commotion. Isn’t that giant bonfire too hot for the mermaids?”
“That’s fine. When they’re in human form, they’re strong against heat. So they even use fire for cooking.”
A new discovery. Mermaids use fire. I’d like to try Sonya’s home cooking. It’s bound to be a seafood extravaganza.
Surrounding the large bonfire, the White Lily Corps, the crew, and the mermaids sat and danced, enjoying a luxurious meal.
The young sailors’ eyes were drawn to the naked mermaids, and seeing some of them disappear, I assume they were captivated by the mermaids’ charm or they captivated them… If it’s a consensual party, then it’s okay. Just don’t lay a hand on married women or pregnant women!
“Um… Mermaids don’t wear clothes, right? Aren’t you embarrassed?”
“Not at all. Rather, why do you wear clothes?”
This must be a difference in biological values. However, seeing beautiful naked women in human form makes it difficult to know where to look. That’s why I should look where I want to look. That’s biology.
“How about the cold? Do you feel cold in human form?”
“It’s warm here, so it doesn’t bother us.”
This is a southern country. A paradise for light clothing. There’s no cold, right? Water might even be warmer. I’d love to swim with you, naked… in human form…
“Try touching me.”
My right hand, guided, rested on Sonya’s left shoulder. I see, it feels a bit cold, but is that because she’s a mermaid? And it feels a little wet.
“You seem alright.”
I moved my hand from my left shoulder to my right shoulder, checking the warmth of both shoulders. Then I leaned in to check my entire body’s warmth.
My body temperature seems warmer. But I can’t tell through my clothes. If I had a thermometer, I’d want to measure it, but I don’t. If I don’t have it, I have to think of other ways… hands…
I lowered my right hand, and from under her armpit, my hand slipped forward to the gentle mountains ahead to measure their temperature.
“Ah…”
The peaks of the mountains were soft, and it felt like they would sink with just a light touch. It would be a waste to make them sink. But the soft mountains, which seemed to swallow my entire fingers, stood proudly, making Sonya’s body writhe.
“Ah… Over there…”
Sonya led me away from the campfire. While everyone else was in their own places, talking about love, the beauty of the merman who chose the male role as an hermaphrodite was striking. He looked like a male actor in some opera troupe. I wonder if their facial features change when they take on that role? A new discovery.
Sonya chose a rocky area that was hidden from view, but there were already three couples there, whispering sweet nothings. I didn’t want to intrude, and it was a bit scary to be too close, so I used Godspeed to change locations.
“Here…”
I might have run a bit too far. The fear seemed to naturally increase the speed of Godspeed. But from here, no one can see us or hear us. Of course, no screams or moans.
We kissed, and I began my investigation of her behind. The texture was good! It still feels a bit wet. Is it because she’s a mermaid? And the modest size, is it for swimming?
Sonya wrapped her hands around my neck, but whenever she did, I couldn’t help but feel like she was strangling me. Is this a professional hazard? I extended my left tentacle prosthetic and gave up.
While kissing, my right hand went to her chest, and my extended left fingers went to her private parts. The wetness on my right hand was within expectations, but the amount of love lubricant that my left fingers got entangled with was surprising.
Noticing my partner screaming for release, Sonya gently pulled away and knelt in front of me. She unbuckled her belt and lowered her pants, and my bursting partner hit Sonya’s face.
“I-I’m sorry…”
“It’s fine. Youth is amazing.”
Even though she said that, Sonya looked younger than me, but I decided not to ask a woman her age. In Japan, asking a woman’s age is taboo, but in another world, it’s beyond taboo, it’s dangerous.
Elves have long lives, and dwarves live longer than humans. If mermaids also have long lives, then asking their age might make my partner deflate.
I’m not the type of man to judge by appearance. However, biologically, I have to ask. But depending on the answer, I might have to sacrifice my partner. Am I supposed to risk that?!
“S-Sonya-san, how old are you…?”
Why did I ask?! Is it biological instinct?! Did I consider the consequences of that answer?! Can I take responsibility?! I could hear those voices from my partner, but I asked anyway.
“I-I’m sixty-eight this year… Ah, this magnificent rod…”
Endure it, partner! Grit and determination, and Sonya’s appearance! I must have misheard. Or she’s joking! She looks eighteen, there’s no way she’s sixty-eight! I made my deflating rod take me in, forcing it a bit, and endured with grit, determination, and friction.
I endured and… finished. While telling myself not to rush, the white milky fluid that filled my mouth caused Sonya to cough.
“You… you didn’t have to rush…”
I wasn’t rushing. I was just surprised by the gap between her appearance and her age. The gap between fish and human form is surprising, but eighteen years old, sixty-eight years old…
Suddenly, I remembered. What about the White Lily Corps?! Humans are Christine and Sophia, and there’s Rufina, who sometimes turns young.
Priscilla is a lycanthrope, Alana is a cat demi-human, and Orietta is a quarter-dwarf. How old are these three?
Perhaps Priscilla is over a hundred years old… Maybe Alana is younger than ten… Orietta, judging by her appearance, is hard to tell…
“You’re still young…”
Sonya turned her back to me and placed her hand on a large rock. The visible secret cave invited me, who was confused, urging me to come quickly and insert.
Don’t hesitate, self! Justice is with me! I reprimanded my deflated partner and flowed magic into him. Demon blood turned my partner into a single short sword.
Youthful exuberance, I thrust in without hesitation. Sonya’s lewd voice, louder than the waves, echoed and stirred my heart.
“Ah… you’re starting so soon…”
You wanted me to, didn’t you? The love juices flowed out, as if to remove frictional resistance, making my Godspeed even faster.
“Ah… such a… you’re hitting the very back…”
The short sword possesses sufficient length, thickness, and hardness for humans. But it’s not just about hitting the back.
“It… it scrapes… it scrapes for so long…”
The longer the stroke, the longer the scraping. And with Godspeed. You can’t experience this anywhere else.
“Ah, nngh… Ah, aah… cck, nngh… aah…!”
You can’t even speak anymore, can you? At least savor it until the end. I sprinted through the final lap with Mode Three.
“Nnnnngh, Nngh, nnnnnh, Nguunnguunng!”
I finished, and Sonya finished. Then, from an unseen location, a laser was fired.

Life in Another World Isn’t Easy
異世界に来たって楽じゃない。
Status: Ongoing
After being reincarnated into another world, I was picked up by a mercenary group—and before I knew it, I somehow became their leader.
The members are all troublemakers: a lycanthrope, a walking disaster magnet, a jealousy freak, a necromancer, a cat demi-human, and a mad alchemist. They all love fighting—and they love me so much they might actually kill me someday.
Was it fate that I was chosen as their leader? In this mercenary group that feels more like a chaotic harem, I’ll do my best to survive.
If only it were a normal harem…
If anyone wants to trade places, please be my guest.
This is the story of a reincarnated man who would later be called a hero—
and of how he was nearly killed countless times by his own harem before earning that title.
