I don't know why, since I started reading this work, I had the urge to do a re-imagining of it with a few more characters, they would be two of Izumi's friends who would be brought to this world with him, and would live this story with him (this idea got stronger as I read and imagined these characters interacting, mainly because of the lack of connection of some characters with the MC, like Ruby, who despite seeming like a really great choice, if you look closely you can see that they don't have much in common that would allow them to bond or create a relationship so quickly) I went too deep into this part, let's talk about the two extra characters, they would be, as I said, Izumi's friends from his past life who would come to this world with him, one of them would be Seth who would have the Cu Chulainn Lancer and Berserker class models, and the other would have the Emiya (Archer and Alter) and Kiritsugu Assassin (I love Fate) models assuming the name of Shirou, then I would add the world of Fate/Kaleid to give background context (nothing about the multiverse, much less magical girls and Zelretch), of course it will be adapted. I WILL DO THIS ONLY WITH THE AUTHOR'S PERMISSION, AND THIS IS JUST AN IDEA I DON'T KNOW IF I WILL REALLY DO THIS (CREDITS WILL OBVIOUSLY GO TO THE ORIGINAL AUTHOR)
