I'm happy for the good reception the story is having as well as grateful for the help and suggestions you give to the private. At the rate we are going, my main idea of making this story in One-Shot style, dedicated in the setting of Muramasa's forge gradually receiving new characters, where the main goal is to create the romance of Rimuru and Ciel, is falling apart. There are comments to send the main characters of this story (Muramasa, Rimuru and Ciel) to the universe of Mushoku Tensei. To integrate Ghislaine into a romantic interest for Muramasa. Plus help on where we can place the story within the canon of Tensura, hovering around chapter 150, looking for it's Arc 8. I want to know which is better, the web novel or the light novel. Since I would have to read to know the background of what happens Tensura Volume 8. And look for a way to naturally integrate Muramasa of what would happen in Volume 8. I will continue to continue the story as I had planned, maybe this way Muramasa can naturally integrate what may happen around Rimuru, already having a reason or behavior of wanting to help her (take care of her partner).
If you allow me first to settle the relationship of Muramasa x Rimuru x Ciel, we can easily start the story within the canon in Volume 8. As I mentioned, I had planned to make the story One-Shot style, I did not seriously think of writing the canon of Tensura and not to make too many chapters, in total I had planned between seven and ten chapters.
I look forward to reading your answers.
