English is my second language, and in my native language I have never written anything resembling a complete work. I write fanfiction to improve my English and writing skills in general. Please be understanding. (I am still open to constructive criticism on any points).

And of course, I do not own danmachi or bloodborn, as well as the original characters for the works.(Found the cover on Google images, if this causes any problems please contact me). I consider only the plot of this particular fanfic and OC to be mine.
