Reborn in Danmachi with memories of 2 past live's & Emiya's Powers

One day a boy who was outcasted from society at a young age due to his inability to socialize finds solace in sports and reading numerous fantasy stories in place of human interaction. He particularly grows fond of a story called Danamchi, going so far as to read the novels, play the games, and read forums and interviews to enjoy it to the greatest extent. Eventually, Truck-kun came to say hello and spelled his end. But it was not yet the end of this anti-social loner, as he soon woke up in the body of a character he was all too familiar with. "I've been reborn as Bell Cranel?!... AND I ALSO HAVE EMIYA'S PROJECTION MAGECRAFT WITH A SYSTEM?! ISN'T THIS TOO MUCH OF A CHEAT?!" Follow our Protagonist as he tries to master the Blade while selfishly doing whatever he wants. Authors note: Hello! This will be my first fanfiction. I'm a big fan of Danmachi, Fate, and type Moon stuff I also recently got inspired to write this fanfic. 1st, this story will mostly be the same as the canon of the original Danmachi with the inclusion of some fate characters and some game elements, and other references from other anime to spice things up. 2nd, I plan to make this story a harem, though I don't intend to make it so that every girl immediately falls in love with the MC for an arbitrary reason. I'll try my best to flesh out each romantic partner in a way that isn't like a stereotypical anime romance. 3rd, The mc isn't going to be some chad thunderc*ck guy, whatever that is. He will have the sensibilities to recognize and acknowledge the horrible stuff in the world, but will not be some innocent snowflake like the original Bell nor some murderous maniac pragmatist, maybe. Lastly, though I included the R18 tag, I am still new to writing lemons. So don't expect too much of those. though I will promise it will happen sometime in the future. Disclaimer: I don't own the cover image! It's an image I got from Google that matches or is similar to the appearance of the MC and will be used until I can have one commissioned. If you want me to take it down just leave a review saying so!
