A materials scientist reincarnates on Azeroth sometime before the First War. Naturally, the first order of business is figuring out why the hell his perfectly mundane technology insists on spewing self-defeating ritual magic everywhere. Clearly, the method to Arcane's madness was being deliberately obtuse. The Light, sadly, didn't seem to be in on the joke.

[Rewriting in progress] Emiya Shirou was reborn as Theon Greyjoy. AU

Naruto Self-Insert. Just because you find yourself in Konoha doesn't mean you forget every other anime you've seen. [I'm sorry for the exposition dump. I've been trying for two years to figure out how to do it better but it just bogged down everything too much.]

When I sold my soul to the Devil, I thought I was prepared for anything. I wasn't. I didn't expect him to be a her. Or dressed up as a magical girl carrying a pink wand tipped with a cheerful yellow star. Her being a prankster however didn't come as much of a surprise. You know, the Bible would have been a whole lot more interesting if they included stuff like this. Complete AU

Hello. My name is Natsuki Senju, ninja extraordinaire! I wasn't always like this though. Just a little while ago, I was dying in a sick bed, with a different name, a different face, and a different life. I guess reincarnation has it's perks, not that I always think about it that way. Quasi self-insert fic

Naruto had never thought she would end up in the past. Not even the one who caused her to go back had anticipated she'd be dragged along for the ride. The Kyūbi had been trying to save himself - not her. She'd once said that the hero always arrive late, but this was quite the opposite. Naruto would be very, very early this time. (Fem Naruto story) Hiatus

It was just a simple good luck wish. This innocent moment created a connection between two lonely children years before destiny intended. This unintended new connection will change the course of history.

Surviving in the 78th district of South Rukongai was tough. When you were a ten-year-old girl with a baby to take care of, it was even harder. Getting reincarnated as Kuchiki Hisana after dying of cancer was never part of the plan. SI/OC, Pre-Canon

Due to a paperwork mistake in God's waiting room, I was reincarnated with my memories intact. No pain, no gain, or so they say. But with a bit of luck, this might just turn out alright.

This is a Taylor Hebert centric story, starting just after the locker. Details after that are sketchy ...

I was dead and gone. Nothing was left, and no one would miss me. Everyone I cared about was dead or betrayed me. I never did anything in my life, and all my chances to achieve my goals were gone. So now I will descend into Hell, like I always knew I would, and be tortured for all the wrong I had ever done... Just kidding. Karma's a b*tch!

Life as a ninja. It starts with confusion and terror and doesn't get any better from there. OC Self-insert. No pairings.

Being reborn without the 'reset' button being completely pushed is awkward enough. It's doubly awkward when your father turns out to be a future famous alchemist.

(Paternal!Roy, Future Royai)

I was the first Hyuuga in five generations to be born without a Byakugan. Arranged marriages and clan conspiracies were only the start. In stamping on a few too many unsuspecting butterflies I managed to change more than I bargained for... but, I mean, the Uchiha massacre wasn't that significant, right? SI/OC

Part 1 of 3. No one ever said an SI gets a place in canon events, or that they would be ideally placed at all. How much would you recall if you had decades to go before anything in a long forgotten story comes to be? AU, Thief!SI/OC, Pre!Fated Day Arcobaleno, very Pre!Canon

Tobirama knew bringing back the dead was possible. He knew that anything was possible in the ninja world. That didn't mean, however, that he ever believed in reincarnation. But here he was, with a new family and a ragtag group of friends, in a village he barely recognized, facing the same demons as before. Would he ever find some peace and quiet?
