Creature Girls: A Hands-On Field Journal in Another World (2025)

"Whether they're part cat, part horse, or part spider, Daisuke has always been fascinated with the uniquely exotic beauty of monster girls. When he finds himself whisked away to a fantastic world full of all manner of demihuman life, he swiftly gets to work meeting (and analyzing!) as many as he can. There's really only one logical thing for this stranded scientist to do: he's going to become the creature girl harem king!"

"DO IT FOR SCIENCE! When he landed in a new world full of monster-folk, science graduate Daisuke had exactly two goals: learn everything he could about them and add one of each to his own personal monster-girl harem! With a harpy at his side and the whole tribe of Arachne spider-women now among his allies, everything's looking up for Daisuke, even in the face of hostile monsters. Unfortunately, another Earthling is out there somewhere in this new world who may have a slightly tougher time..."

"Kurimusubi Daisuke, a man fascinated by the complex zoology of monster girls in fiction, one day finds himself transported to a world full of them! When he encounters an arachne named Neya who needs his help, Daisuke rushes to help her-which begins his new life of meeting (and researching) the beautiful creatures around him. These monstrous ladies show him that he has a lot to learn, and Daisuke never dreamed he'd be able to satisfy his passion for monster girls like this!"

"A MENACE RISES FROM THE DEEP Science graduate Kurimusubi Daisuke has brought peace and prosperity to the fantasy world he now calls home. Plus he's making excellent progress on creating a creature girl harem, studying the anatomy of every species of monster girl he comes across! But suddenly, as he's investigating the body of the merfolk clan's princess, their village is attacked! These mysterious, hostile entities are known only as 'Deep Ones,' and there isn't much time to rally the village. It's finally time for the Harem King to lead his creature girls into battle!"

"Thrown into a strange fantasy world alongside his best friend Daisuke, Taishi Oritasue has a laundry list of problems: a strained relationship with his maids, having to flee his kingdom, and then an encounter with a group of particularly hostile goblins! He does his best to settle down into goblin life, but when adventurers come knocking, he's in for even more upheaval! It's time for Taishi to get some of that otherworldly harem action!"

THE HAREM KING IN THE LAND OF CENTAURSDaisuke Kurimusubi wants to be the Creature Girl Harem King, and the next candidate to join his coterie of demi-human beauties is a centaur maiden. But winning her over requires winning over her tribe! Despite the centaurs' deeply unorthodox approach to sexuality and gender roles, Daisuke's managed to establish a position for himself in the centaur village and win a little bit of their respect. The looming problem, however, is the horde of minotaurs plaguing the nearby grasslands. Before Daisuke can find the right way to deal with them, conflict suddenly breaks out! It's a battle between the minotaurs and a band of trolls and orcs!

THE HAREM KING AND THE KING OF DARKNESSWhile Daisuke Kurimusubi wants to be the king of a monster-girl harem, his old friend and fellow earthling Taishi Oritsue has become something closer to a Demon Lord. Between rounds of carnal debauchery, Oritsue has overcome even the mighty basilisk and begun innovating on all sorts of unorthodox inventions. What's more, the maids who once looked down upon him now desperately wish to bear his children. The nation under Oritsue's control grows more powerful by the day! And out at the centaur village, Daisuke's quality time with Nea is interrupted by the emergence of a mysterious "headless woman" from out of the darkness...

GETTING HEADLESSDaisuke is living large as the Creature Girl Harem King. After helping Yura get her revenge on the manticore that ripped off her head, he's added the Dullahan woman to his ever-growing group of wives. There's certainly something strange and special about a woman who can remove her head anytime she likes, and Daisuke's inner scientist can't wait for a hands-on examination! Meanwhile, Oritsue is staring down an incredibly intelligent dragon, one whose uncanny wit is matched only by its nation-destroying strength. It'll take every piece of tenacity and warrior prowess Oritsue has to survive the encounter!

A MERMAID PRINCESS AND HER MAIDSAs the Creature Girl Harem King, Daisuke is always looking for new monster girls for both his scientific and erotic explorations. His latest tryst is with mermaid princess Kana's fish-tailed maids, who are only too happy to get their hands (and fins) on an otherworlder like him. Daisuke's continuously using his modern scientific knowledge to create new contraptions, this time creating vehicles never-before-seen in the world he now calls home, and the local ladies love him all the more for it. Meanwhile, as winter settles over the Death Mountains, Daisuke's old friend Oritsue prepares to negotiate an alliance with several nearby demihuman species...

A BLOODY REUNION IN ANOTHER WORLD!Not long after Daisuke and Oritsue were transported to an entirely different world, their fellow university student Fuechi wound up there too. Fuechi happens to be an expert in the Oritsue family style of martial arts, and he's found a comfortable place for himself teaching the fine points of combat to Repuburiku's elite forces. Their soldiers have been tasked with taming the wild places of the Death Mountains--bringing them into inevitable conflict with Oritsue himself, who rules over the Mountains as the master of the Midori goblin tribe. Human forces grapple for supremacy against the newly-formed Demon Lord's Army!

FORBIDDEN SCIENCE AND FORBIDDEN DESIRES!Much to Daisuke's amazement, a pair of genuine, pointy-eared elves have arrived at the Ra Clan village. The two of them are mother and daughter, and they hope to obtain some of Daisuke's otherworldly scientific knowledge. High elves like them are the product of countless generations of carefully-managed breeding, a program designed to produce immensely intelligent minds. But in a world where technology has been mysteriously suppressed, there are still many questions even living computers like them can't hope to answer. In a private meeting with Daisuke, they reveal shocking truths about their world...and soon after, they give him an erotic experience he'll never forget!

ONCE A NERD, NOW A DEMON LORD--AND MASTER OF ALL HE SURVEYS!Thanks to his scientific knowledge and tremendous martial arts expertise, Taishi Oritsue has transformed the Midori goblin clan into a dreadful fighting force worthy of being called "the Demon Lord's army." Despite living in the horrifying Death Mountains, they live a comfortable life with amenities--and orgies--the outside world can only dream of. Yet they may have met an unexpectedly strong opponent in the forces of the human Republic. Their tenacious soldiers are trained by a man who practices the very same Earth-world martial arts as Oritsue himself!

THE POWER OF "CUTE" CANNOT BE DENIED...DO NOT RESIST!Daisuke has gathered an eager harem of all kinds of monster girls, and his scientific know-how is hard at work keeping the winter cold at bay. The appearance of some mollusks and slimes in the village seems like a minor nuisance...until the sudden arrival of three irresistibly cute individuals who call themselves "slime girls"! Daisuke's very excited to see one of his favorite fantasy tropes come to life, but might there be more to these slime girls than meets the eye...?
