I Hatched as a Worm
I open my eyes… No. My eyes won't open.
What the hell? I remember hearing that a new erotic magical girl game starring my absolute favorites had dropped, yanking my pants down and firing up the computer…
I tried calling for help, but it was like I'd forgotten how to make a sound entirely—no voice came out at all. The silver lining was that I could still move, though my senses felt weirdly off. It was like wriggling through a dirt field… Had I been buried? Why?
As I gradually shifted, the gritty texture of soil scraped against me. Naked or simply without clothes, the dirt stung harshly enough that a slick liquid began oozing from my body.
…?
It wasn't the precum that dribbles out when you're jerking off on the floor—this was like salty precum secreting evenly across my entire body, and it filled me with an indescribable unease. On top of that, my hands and feet wouldn't move and I couldn't see a thing, so I'd assumed I was buried. But I could move my body, and I only felt the dirt floor against the underside of it.
Something about my bodily senses was gradually coming alive, so with nothing to see anyway, I focused on what I could feel. Judging by the overall sensation, I felt like a plump, slightly chubby earthworm—a cylindrical form. And I was half-convinced: I had become something that wasn't human.
As I adapted to the unfamiliar body over the next few minutes, I grew used to it surprisingly fast. I lifted the body that had only been crawling, curled myself into a ball, rolled around testing things out—and gradually, my vision seemed to return. My surroundings started coming into view.
Well, if you could call it "seeing." It was like looking through a thermal camera—a world of mixed blues, yellows, and reds. Still, I could make out the outlines of objects well enough to confirm that I'd just broken out of an egg, and that I'd become some freshly hatched worm-like creature, incomplete vision or not.
Holy shit…
I love magical girl stuff—especially the kind where magical girls get taken by tentacles—but I never wanted to be born as a helpless worm like this… If I was going to reincarnate, couldn't I at least have gotten hypnosis or aphrodisiac abilities… or hell, even just been an erotic tentacle that could dissolve clothes with slime?
No. It's too early to give up.
Looking at the current situation from an omniscient fapper's perspective, the odds that I'd become a tentacle from the erotic game I'd been jerking off to right before I died were at least 50,000%. In other words, if I didn't give up here and trained myself properly, doing all those filthy things with magical girls just like in the game shouldn't be out of reach…!
—Coo.
Roll left!
—Coo-coo-coo!!
What rudeness! Charging in without even a greeting—beasts really have no manners. I slightly escaped into fantasy while spinning my brain to get out of this situation.
I'd been curious about my body size, and while I couldn't be sure from the thermal vision, judging by the cry and silhouette it was definitely our neighborhood pest—ugh! the GreenOnionPancakeLover pigeon, no doubt about it.
Gyaaaaah!!
I was shocked once that I was about the same size as a pigeon, and shocked again that pigeons were this fast. They weren't the dumb creatures that just waddle around blankly and only fly off if you seriously threaten them!!
—Tumble tumble tumble.
—Coo coo coo!!
Gyaaaaah! I've never been a goggle-wearing vampire hunter or anything like that!!
"A real man is melee DPS, not some ranged carry…!" Even in this desperate situation, my brilliant ADHD couldn't stop the useless thoughts from flowing—and it shone. They say ADHD is advantageous for survival after all! From those useless thoughts, a brilliant idea flashed.
—Tumble.
—Coo… coo?!
—SMACK!!!
That's right—I was born a melee DPS spoon!
Realizing my true identity, I rolled once more to bait the attack, then immediately went full throttle on my tail muscles and smashed the pigeon right across the cheek!
—Flutter flutter!!
True to form as a dumb pigeon, getting slapped across the face left it completely stunned, and it frantically flapped away in shock.
Heheh, victory is mine…!
If this were a typical isekai, a status window would've popped up and given me experience points or something—but sadly, I was a pathetic low-tier tentacle who had to fight a life-or-death battle with a mere pigeon, so none of that happened.
—Growl.
Whether it was because I'd just been born, or because rolling around with a Rolling Thunder had drained my energy, I felt hunger setting in. I vaguely remembered hearing somewhere that creatures hatching from eggs eat the egg byproducts or the weaker siblings born alongside them, so I glanced around the place I'd woken up—but for some reason, there were no siblings in sight. Only the byproducts of the single egg I'd broken out of sat there alone.
It seemed to be cooling rapidly. In my thermal vision, the outer surface was bluish-green while the inside still held a faint yellow of residual warmth. Setting aside complicated thoughts for now, I started eating the egg byproducts before they cooled any further, to fill my stomach. Fortunately or unfortunately, I couldn't taste anything, but the texture was chewy like the pearls in bubble tea, so it was edible enough.
As I filled my belly and thought about what to do next, a sense of helplessness washed over me. No reincarnation cheat skills to be found, and a body so weak it had to fight a pigeon to the death. Just as I was worrying whether I could ever become like those tentacle seniors from the erotic games, I sensed a presence.
"Ah, it hatched!!"

Just from the voice alone—so bouncy and anime-character-like that if I'd been gender-bent instead of turned into a tentacle and had a voice like that, I could've made a living as a VTuber off the voice alone—it echoed through the cave. Fortunately or unfortunately, I could understand the language, which was a relief. I looked toward the source of the voice—
—Crack!
My eyes went so wide that if I'd had glasses, they would've shattered. Even through thermal vision, I could tell this woman's massive breasts were bigger than her head, and I was stunned.
—Boing boing.
They were so huge I could almost hear sound effects that shouldn't exist. My gaze locked onto them, but sadly I could only gauge their size—I couldn't appreciate them in the high-resolution, high-definition quality of my human days. Her breasts were so overwhelming I almost resented being reborn as a tentacle.
Poke—poke—
"Hehe, thankfully it's healthy~"
The woman carefully poked me as if checking that I was alive.
Aah, a woman shouldn't just poke a man's long thing like that without permission…!
"It's so tiny. I heard tentacle larvae are small, but it looks just like a worm~"
Ugh, tiny…? How can you say something so cruel to a man! I used to be big!! Not that I ever got to use it…
I enjoyed her touch while making excuses that would never reach her. By the way, in the game I used to play, tentacles were classified as monsters and targets for extermination… Was it okay to just stay like this? Judging by the circumstances, it seemed like this woman had placed the egg I came from here separately.
"Hehe, it's soft and feels so nice~ Hmm, I was worried since it hatched first, but it looks like it only just hatched. What a relief~ The mana organ doesn't seem to have formed yet."
Ooh, some fantasy setting details just dropped.
"Alright then, before the mana organ forms… Ugh~ Extracting high-purity mana while keeping the output at minimum is harder than I thought."
She stopped stroking me and started concentrating something at her fingertips, muttering as if troubled. What is that? I could feel something, but even with thermal vision nothing was visible—yet something was definitely gathering at her fingertips. Was that mana?
"Phew~ Done! Come on, little tentacle. Eat this up~"
Muttering to herself, she carefully pressed the hand that had been poking me against the head end of my body. The energy became even clearer. Drawn by that unknown power, I opened my mouth as if entranced, carefully bit down on her finger, and sucked on it like a nursing baby, drawing in the energy.
Compared to the egg scraps I'd eaten to ease my hunger after that life-or-death duel with the pigeon—a once-in-a-lifetime all-in brawl—this was a completely different dimension of satiety, more fantastically delicious than any food I'd eaten as a human.
As I absorbed this unknown energy—mana—in a trance, a sensation similar to a full-body tingle, yet somehow alien, washed over me. I felt my body growing in real time, and simultaneously felt the mana she was supplying flowing into and settling within me—and at the same time, I could sense the pathway through which her mana was flowing into me.
Following the channel from which the mana poured forth: a heart that pulsed and emitted mana, a brain that gathered and condensed the emitted mana according to her will… and finally, a womb that held such overwhelming mana that even the gentle aura seeping from it—independent of both heart and brain—was palpable.
And I realized… that place would become my new home.
