The Multiverses of Honkai impact 3rd, Honkai Star Rail, Genshin Impact, Zenless Zone Zero and Gun Girl Z fused together, distabilizing the reality itself. In this new Omniverse, men doesn't exist anymore and the few that didn't dissapeared turned into females. Without men in this society, the birth rate got lower despite the major scientific advances and the control of Magic, Honkai and Genetic. In this Story, our Protagonist, Shirou Kazuki, a young, handsome and cute adolescent who happens to arrive in this new complex dimension without any idea of what he is doing here and how he get there, will have 3 major goals bestowed upon him : 1. Increase birthrate at maximum efficiency. 2. Find a way to bring back men turned into women. 3. Discover his new powers and abilities. With his harem full of gorgeous women, ready to help him whatever the cost is, he will eventually find all the answer he seeks. But will he survive in a world where all women wants him ? Will his "friends" be able to resist the temptation of claiming him as theirs ? And will he succeed in his missions despite the fact that other verses full of women could be involved in the future with this Omniverse already ?

A storm god approaches and destiny follows with him. While the rest of medieval Karnassis is ushered into the industrial age by the outlanders of the Öd, the humble island of Dyma clings to the past. They prepare for a time honored tradition -- the arrival of the Silent Chorus, a divine tempest crafted by Zoreus, the great eidolon of storms. But little do its people know, more than a god is coming to their shores. Mylo has never wanted to leave his island. But with his sister gone and a bond to a demigod accidentally forced upon him, his love of Dyma will be tested, as well as his fear of the world. Verana is leaving Dyma behind to become a powerful summoner, with ambitions to defeat the king and rule all Karnassis in his place. But her brother's shadow still lingers on her, threatening to turn those ambitions to a darker purpose. And a cowardly outlander named Claude hides a devastating secret. And if revealed, it could spell destruction for all Karnassis. When these fates intertwine, events will be set in motion that will change the Etherea forevermore. Cover Art by Amrin A. Sloat

Demons. No one knows how long they have been on Earth, nor how they came to be. But for the centuries they have been around, they have consumed humans with no remorse or regret to satisfy their bloodlust. The Demon Slayer Corps was created to ensure that humanity had some sort of protection from these creatures. They are a secret organisation that is not recognised by the Government. Tanjiro Kamado made it has goal to become a Demon Slayer after his family was slaughtered and his sister was turned into a demon. But he wouldn't be alone on his journey. He would always have his best friend by his side.... NOTE: If you've watched Demon Slayer, then you'll know that it is very violent and involves a lot of blood and people being dismembered, cut to pieces, you get the picture. Also, I do highly recommend that you watch Demon Slayer before reading this story as there will be spoilers. Also also, I am aware that certain girls in the harem are with certain characters from the series. This is my story and it will be adapted to work around having a reader character. Also also also, this will follow the storyline of Demon Slayer, but there will be some filler added in. This is technically a retelling of the story, so some things will be changed. For example, some characters might not die and the overall ending might be a bit happier. There will be angst and a lot of it because I don't want to fully mess around with the story, but there will be plenty of fluff too.
