Hey author-san! I thought of a cool idea/scenario you could implement similar to a side-story. You don't have to since it's your novel, but I think it would add some spice. In this idea/scenario, one of Vahn's clones gets cut off by a mysterious force way more powerful than his body which he can't connect to. The clone would be the main character of this side-story. The twist is that the clone loses most of its powers and becomes as weak as Vahn was at the start of the Fate arc when he just left Danmachi (of course, you adjust it whatever you feel like) without the inner world. I am suggesting this because it would be boring if he was just extremely powerful. I think adding challenges gives interest and meaning rather than just dealing with every problem in a single punch. The clone arrives at some world, like, I don't know, Made in Abyss. I am suggesting this one because I read the entire manga and watched the anime, and I'm in love with it right now. The show is very dark with body horror, so Vahn bringing light into this world would be interesting. Perhaps the Abyss' curse is powerful enough to block off the connection? Of course, my thought pattern would be to throw this clone into a random anime/manga/movie that is not overly popular that other fanfic novels have explored. For example, a recent one like Scarlet Nexus, an old one like Berserk, or maybe even a dark one like Madoka Magica. I am certain no fanfic writer has sent their MC into one of these worlds. Anyway, if you are interested, you could implement this side-story idea into your current novel, or even a new novel if you ever make one. If you don't like my idea, you can just ignore my comment entirely. It's just a random idea I came up with to spice things up.
