Oooh, fanfiction, sure.
Well I’d rec all of Ryuugi’s works.
All of them are super well written with fun characters, great worldbuilding and tons of knowledge. If I had to pull out some stand outs well.
A Dresden Files and Percy Jackson with Percy being reincarnated by Tartarus as a pixie with a monstrous hunger. Ryuugi does a really good job at illustrating Percy’s descent into darkness.
A awesome crossover between Danmachi and Percy Jackson. Unfortunately Bell isn’t here but Percy does a good job of filling his shoes.
One of his actually complete stories. It’s a small crossover between Dresden Files and Tsukihime. It doesn’t really do anything new. But it does everything good.
An old crossover of his, with Percy being summoned as Berserker in F/Z, it’s nice.
Getting into his more recent works this is a pretty good fic. But some might dislike how op Percy is.
If you like chapters full of exposition and op characters styling on plot, you’ll probably like this story. If not, then your probably not going to like this story.
His most recent story, it’s a very good xianxia story.
Getting into fics not by Ryuugi.
A Cthulhu Mythos X Percy Jackson story, Shujin does a good job with worldbuilding.
Already been recc’d but
Virtuous Sons [Greco Roman Xianxia]
Virtuous Sons is a great Greek cultivation story. Griffon and Sol are just such good characters and play off each other really well.
Another amazing Xianxia story with the MC kicking cultivation tropes to the curb and just genuinely being a good guy.
A Fate/Grand Order story with the inclusion of Jesus. Nope that’s not a joke. It’s actually pretty fucking good.
A really good story about Ozma and Salem ending up in the throne of Kill Six Billion Demons. Also one of the only KSBD fics out there.
A place to put all my ideas. Long enough stories will be given their own threads. Updates are according to: Inspiration, Popularity and Reader Requests. Recurring tropes in these works: SIOC | Dimension Travel, Time Travel, Canon Divergence, Fix-It, Crack Taken Seriously and Rare Crossovers...

Everfew’s Takada-chan’s advice is a pretty good Death Note/JJK cross
Villain Notebook for the future is a pretty fun Villain Izuku story actually done right.
A very good JJK/BNHA crossover where Gojo after getting stuck in the Prison Realm gets isekaied to BNHA and hangs around.
A cool crossover between An Impractical Guide To Evil and Percy Jackson, with good worldbuilding and a fucking insane Percy, with an insane plot.
A pretty good MHA and Kamen Rider Build crossover, is a bit to much like canon in the beginning but does diverge soon.
By the same author of Building A Hero, another Kamen Rider crossover is My Hero, Agito. Unlike Building A Hero! The first chapter diverges pretty heavily from canon, unfortunately there’s only one chapter as of yet.
A pretty good Avatar and Percy Jackson crossover.
A very good MHA and Tokyo Ghoul crossover.
Another Tokyo Ghoul fic, this time a RWBY cross.
A really good Re: Zero fic about Subaru’s friends finding out RBD.
A spin off of Forced to Listen, with Subaru leaving the camp due to his issues.
A incredible BNHA/JJK cross with Megumi and Nobara being isekaied to MHA and joining UA to find Yuuji.
A good story about the Sizable Hare.
And I've given up writing my own thoughts right about now. I'll just post links and summaries of my favorite fics.
Summary: A compendium of escapades and lofty labors where Subaru ventures without his faction's knowing across the map, whenever possible. Losing himself in either solving folk's problems, forging mementos with varying people or seeking bombastic stunts in order to quell his morbid fears. Hungering achievements. Greatness, like Wilhelm viewed his loved ones. To prove himself worthy too.
Summary: The Weakest Servant in existence, nothing more than garbage be it a Holy Grail War or any sort of fight. Yet upon gaining a new Master after a hero of justice stopped his corruption and sent to another realm, things just might change. In a land full of Gods and mortals alongside his new Master, maybe Angra can do something with his life. Hero? Villain? Avenger? Only time will tell.
Summary: Bell Cranel was making his way to Orario, an accident occured at which he hit his head. Suddenly, memories of another life came into his mind, the memories of Tomura Shigaraki. Now with the memories of Tomura Shigaraki, but the lifestyle of Bell Cranel, things get a lot more complicated. Well, as long as Tomura gets to destroy, the dungeon should do. But how does he have his quirk?
Summary: Percy broke a promise he made on the River of Styx and has to pay a steep price. Transported to a new world and thrown into another conflict, witness as he struggles to make sense of what's happening, adapts to his new environment, and attempts to unravel the mysteries of yet another monster infested world. Rated M cause I don't want to limit myself.
Summary: Nobody deserves to be alone. To change the fate of the world, and to forever change Natsuki Subaru's fate, everyone will see just what he has suffered. They will finally see his trials, and many will finally learn just what the true essence of their hero is. What will happen? What will change? Let's find those answers for ourselves. Spoilers for EVERYTHING ahead.
Summary: A monster is given a chance of redemption; a new road to follow, filled with new dangers, friends, foes, mysteries, and horrors. Will he succumb to the darkness or find light down this new road? As science and magic collide, a new story is born.
Summary: Karasuba never had any intention of finding her "Destined One"; to spill blood, any Ashikabi would do. With that said, she was never supposed to meet a genocidal maniac as sick and twisted as Emiya Shirou. Maybe romance wasn't dead after all.
Instead of the miracle-bringing Traveller in Aether/Lumine, Teyvat got another outlander. One who was far more useless, albeit influential nonetheless. Natsuki Subaru wakes up in another world and ventures forth to remember the past he had forgotten as well as to find a familiar face from Lugunica. (Spoilers up till Re:Zero Arc 6 and Genshin Impact Theories)
The arrival of a certain young hero shows the world of the Od Laguna just how small it truly is. Basically, Subaru is MCU Spidey and the Re:Zero cast meet Marvel Multiverse madness. Sounds fun, right? (First fic. Shamelessly posting in both regular and crossover sections for reach.)
Living day to day as a messenger in the slums, Ruby thought her life was set out for her. But when a mysterious meeting with an Arcanist draws her into a conspiracy that threatens all she loves, that changes. Wielding the power of a Wildmage and hunted by enemies and Arcanists alike, Ruby must find answers in the one place her kind cannot venture; the Arcane Collegium.
Summary:
Shortly after getting unceremoniously kicked back to Earth, Natsuki Subaru spontaneously combusts. A number of deaths later, he joins the Chaldea Security Organization. And then dies some more.
Minor spoilers for RE:Zero LN, primarily pertaining to Subaru's later powerups.
Summary: Class 1A, and some teachers, are brought to a room by a strange being who has made a deal with them. They will be given information about various secrets and future events, which they could use to save lives, but this information comes at a cost. Every time the 'on screen' version of them experiences pain, they will feel it too. There's no such thing a painless lesson, after all.
Summary: Salem won. Defeated and captured, Ozma was driven into insanity, never to rise against her again. For a thousand years Remnant has lived under the rule of the Eternal Queen, shaped to her whims. Jaune Arc is but a young man suffering from nightmares that aren't his own; driven to fulfil a destiny that isn't his, before the fractured mind of a broken man consumes him entirely.
Summary: With Arc 4 finally having passed, the cast has hopes of never having to watch Subaru die again. While they make plans for what do when they leave, the screen suddenly shows them all a strange meeting that was never meant to take place. An event which answers a few questions and shows what could've happened to Subaru had events played differently in his Past, Present, and Future.
Summary: My name is Jaune Arc and I'm cursed. At least once a week, I am turned into a monster, a beast so horrifying tha- "Guys, Jaune turned into a little puppy again!" "Arf!" Yeah... what she said. (Coverart by KegiSpringfield)
Summary: Being a god, Arceus...
Summary: Louise's summoning of her familiar was supposed to be the ultimate, final proof that she was truly a mage. But, instead she somehow found herself in a place called Raccoon City on an entirely different world. A world where magic didn't exist, and when that world falls apart, she and the boy who was supposed to be her familiar must fight for their lives against the evil around them.
Summary: Remember a time when things made sense? Humans killed Grimm, Grimm killed humans, and criminals could make an honest living? Back before teenagers ruined everything?

Summary: My name is Izuku Midoriya, for most of my life, I was just a Quirkless boy with dreams of being a Hero like my Idol All Might. But I was told without a Quirk, I can't be a Hero. Then I met All Might, inherited his Quirk, and became the Greatest Hero in the World...But before that, I got bit by a spider and now, I can crawl on walls…not how I imagined getting superpowers.
Summary: After the events of Ragnarok. Jin Mori was too weak to continue, but a last-minute save from old friends allowed him to travel to a parallel world to recover. A world with Devils, Dragons, Gods, and...is that...himself?
Summary: The cast from "Watching Him Die Again and Again" by Reactionist, gets to relax after arc 3, however, the warden decides they need to get introduced to the new characters for arc 4. Now Subaru's friends are going to find themselves in the presence of each Witch of Sin which leaves them more confused than ever.
Summary: A non-canon spin-off on the original "Re: Zero Watching Him Die Again and Again" by Reactionist. Cast watches the movie, "The Martian, with Subaru starring as Mark Watney.
Summary: To pick up girls in the Dungeon and form a harem. That is the dream of Bell Cranel, thanks to the tales that his beloved grandfather fondly told him. It is for that reason that he travels to Orario in hope of fulfilling the dream. However, it proved to be more challenging than he thought. After all, how do you fulfill it when you suddenly find yourself married?
Summary: Megumin Potter was always seen as a delusional child who believed that the death of her parents and her mistreatment at the hands of her aunt and uncle were signs that she was destined to be the Chosen One and had dark and terrible powers within herself. Most thought her mad. Unfortunately, she was dead on. Hogwarts will not survive this.
Summary: Da Vinci's latest experiment results in Chaldea mysteriously landing in a brand new world. One where myths and legends are forgotten. For better or worse, Ritsuka Fujimaru is about to revive those fairy tales while simultaneously getting involved in a secret war between an immortal and a witch. Just another day at the office.
Summary: Rin might have convinced him to take the gig, but Shirou had a funny feeling that this wasn't what she had in mind at all. If being a master of Chaldea was dangerous before, then now it was an outright suicide mission. Investigating all of these singularities on his own won't be very fun.
Summary: Momonga, rather than being transported to the new world, is sent to his own real world: the Earth of the year 2138 along with the Great Tomb of Nazarick and with all his powers intact. He just needs to find a way to explain to all of the NPCs that their creators are actually humans- but what will happen when they know of how much their creators have suffered in this real world?
Summary: He awoke in a strange land, remembering only pain and the ravenous desire to search for something lost to him, only to catch the eyes of a passing raven. She thought she had found a priceless weapon, an indispensable tool better than any she could have plundered, in the form of an amnesiac kid. What she received however, was something far more precious.
