Kayaba brother and the crystal witches(futa/male turn into females harem)

This story will have lots of crossovers and I take no credit for ideas I get from anime and light novels and some video games I use in my stories all credit goes the ones who made them also none of the pictures are using my stories belong to me they belong to the people who made them I find all my pictures on Google Chrome images with that being said I will explain a little bit what to expect in the story as the title says the story is about the brother of Akihiko Kayaba yes in this story he has a brother it's also about a group of witches known as crystal witches the name of Akihiko Kayaba brother is Y/n= your name meaning you can make up your own name for the character of the story but I will see making the story the way I want to I just want to explain to people who didn't know what Y/n means Akihiko Kayaba Brother was trying to prove that he's older brother by one year was losing his mind but no ordinary person believed him he tried to explain his brother had a evil plan with the virtual reality he was creating like he's older brother he also wanted to create an world because he always wanted to go to another world but unlike his brother he didn't want to get anyone hurt he just wanted to make a place where people could be what they want to be in a whole different world the time people finally believed Y/n it was too late the game was already fully made and what was meant to be just a fun reality game turned into a death game people ask Y/n find a way to get everyone out of the death game he told them the way he's older brother made the game only by beating the game would they get out there was nothing he could do without hurting innocent lives in the process The story begins a couple weeks after the death game started in the real world with Y/n who was working on a special project find out what he's working on by reading the book
