Answers to all your questions

Hello, it's me again. Obviously. But to answer what happened to Inuko, Naraku is in the past and used a spell that transported her back to that date. If you want to know what happened to her, wait less then a month and I will have my 3rd story up, and it will cover what happens to her, and what roll she plays. The whole thing about the gun and how I knew what it was, is I used to love going to stores and looking at guns, and researching as much on them as possible. About Hoku, Naraku had a son and he taught him everything about what he did and how he did it. So his son had used a shikon shard that his dad had given him before he died. And although the shikon no tama did not have it, it was still whole. And because of this, he did to Hoku what his dad had done to Sango's little brother, who cowhensidently shared the same name. And before you ask, that was not done on porpose. What happened with my parents is that my dad had gone inside to check on my mom who was being attacked by naraku's son. I had to kill Hoku because he would not back down till one of us went down permently. Feel free to ask any more questions.
