I have tried to match their personality as best as I can, and Yahiko isn't fully in this, Nagato is still controlling him I just have this headcanon where the red head did something to reverse his body to its original state but that was short lived after he realized that he was going back to his weak body but did try and keep in contact with the woman and he didn't really fully explain what was going on to her- but this book is my own idea after I saw that there wasn't many scenarios like this.
