Description

Welcome to a Sexy, Open World
A brand new title from MOONSTONE Cherry, the creators of Imouto Paradise - Welcome to a Sexy, Open World!

When the young Sejima Seiya tries to rescue a dog, the passing truck winds up sending him straight into a completely different world! In this brand new world, Seiya finds himself caught up in an ancient prophecy that someone from another world will arrive to give birth to the legendary heroes that will end the wars plaguing the lands. What is Seiya to do as key women from every major nation in this new world start accosting him for his baby batter in an attempt to ensure their nation holds the most influence over the heroes destined to be born?! Worse yet - even if Seiya wanted to avoid becoming a stud, it turns out that if he doesn't create a child to bind his presence in this new world, then he'll be pushed out of it and sent back to the moment of that fateful accident! Luckily for the unwitting father of heroes, coming to this world has given him the power to know when a woman is at her peak fertility!

Description
When he awakens from a terrible accident, Sejima Seiya finds himself in another world—Laurentide.

A world with a legend, long held by its people:

──The seed that shall give birth to heroes and end the era of war shall come from another world.──

Seiya has that seed within him.
And despite being viewed as breeding stock, he still wishes to have sex.
But now the father of the future heroes could become king of the world.

So...

Drawn by the legend, beautiful women gather from across the world, seeking his seed.

──Or perhaps some harbor the ambition of unifying the world under their motherland.
──Or perhaps some simply desire sex with Seiya.

Regardless, Seiya's days of getting milked by beautiful women have begun...

Description

The proud female knight of the Empire.

Profession: Knight of the Imperial Guard
Country: The Holy Imperium, Valhalla
Race: Human
Height: Slightly tall
Breast size: Big

Under instruction from their gods, the great western empire of Valhalla seeks to broaden its' lands.
In Valhalla, Alencia holds the vaulted position of "Head of the First Order of Imperial Knights, in Guard of Her Royal Princess", which is to say she is the strongest knight.
In order to further spread the influence of Valhalla's gods across the world, she travels to Laurentia, to take the hero's seed.

Her pride is excessive, to say the least, and her tendency to shout "I'll kill you for that!" at the slightest provocation tends to make those around her quite ill at ease.
While she was rather curt with the protagonist at the start, after he saved her from an energetic orc, she quickly finds herself falling for him.

「Though I know it's for the Empire, to have to take the seed of a pitiful man such as yourself... I'd just as soon kill you.」

Description

The beauty who's a genuine star, yet still manages to be good humored and kind

Profession: Dancer
Country: The Center of the World, Laurentia
Race: Human (Quarter Nymph)
Height: Tall
Breast size: Extremely big.

The biggest theater in Essenbaum (and thus also the biggest theatre in the entire world) is the "Golden Theatre".
To take the stage there is the highest honor a performer could hope to achieve, and of all the theatre's performers, its number one star is Elda, the Dancer.
Up until now, the stage was all that Elda ever thought about, to the point that she avoided associating with men.
However, on meeting the hero she starts to think "Marriage and having children, maybe those could be good, too?"

She is Anna's elder sister, and the two have a really good relationship together.
Since she's a quarter forest nymph, there are some who theorize it's her magical Nymph charm which makes her dancing as appealing as it is.

「If it's for you, and for your child, I have no problem giving up my life as a dancer.」

Description

The listless Princess who has an immense interest in the erotic?

Profession: Princess
Country: The distant realm of Elfheim
Race: Elf
Height: Tall
Breast size: Smaller than others, yes, but still quite big

In the far off kingdom of Elfheim, the elves live in peace and harmony. Under instruction from the King who desires nothing but peace, the princess Eritte arrives to receive the seed of the hero.

Though rather somber and always bringing a downer mood to those around her, Eritte actually really loves lewd things.
She also really loves the protagonist, who managed to become her very first partner.

Elves being elves, they spend most of their time living in the forest... which makes them a little lacking when it comes to common sense. As a member of Royalty, she bears no family name.

「Guess there's no way around it... It's for the peace of the world and all that. I'll bear your child...」

Description

The tough female swordswoman with the urge to breed♥

Profession: Samurai
Country: The island of the rising sun, Akitsushima
Race: Human
Height: A little short
Breast Size: Big

While the country does not boast much in the way of power, the people of Akitsushima are a warrior race, who hold pride in the fact that their country has never once been defeated since its' creation. In all of Akitsushima, the girl Kashima Hikari alone is feared as the strongest at the sword. For the sake of her country, she has traveled to Laurentia to steal the seed of the hero.

She challenges the hero to a duel, but the power of the hero reaches directly to her (to her womb), and she inadvertently drops her katana. But for samurai of Akitsushima, one's katana is an object more important than their life. As such, Hikari admits her defeat.

「The man who knocks me up, he must be none other than the strongest man in all the world!」

Country: The promised land of Sumerian
Race: Diva (demigod)
Height: Average
Breast size: Extremely big

Long, long ago, before humanity even knew how to write, existed Sumerian. The land granted by the gods. In that land, prostitutes are revered as priests...
But even though that is true, Madorie still would rather not embrace a man she does not love. And so, possessing only the clothes on her back, she fled from Sumerian, all the way to Essenbaum. There she has her fated encounter with the protagonist.

With an existence like that of a goddess, Diva women have given up on men as husbands, yet still seem to possess overflowing love and maternal affection...

Description

The wandering fortune teller.

Profession: Fortune Teller
Country: The Women's Autonomous Commune of Yoshinohara
Race: Youko
Height: A little short
Breasts: Big

Whatever a man's heredity or position may be, whatever his rank or social status may be, the moment he steps foot past the gate to Yoshinohara he is stripped of all of them until he is nothing more than yet another naked male. In this autonomous community of Yoshinohara, Yuuna befriends the prostitutes whose troubles are so many, and runs a business at divination and fortune telling. Her magical abilities are so strong, she has gained a reputation at being able to divine most anything; from the identity of your lover's adulterous partner to that thing you lost and have been looking for, she can find it all.

As a native of Yoshinohara, Yuuna's speech tends to reflect that used by the courtesans and prostitutes she lives with, though she herself is no lady of the night. She hears rumors about the Hero Who'd Be a Father, and decides head to Laurentia to maybe go tell him his fortune. Though... for all her ability at telling the fortune's of others, she has never been able to tell her own future.

「If it's you and I, master, no doubt I'll give birth to a beautiful gem of a child.」
