He didn't know the first thing about running a school, nor fixing a political disaster spanning all of Remnant. Hell, he didn't even know how to deal with the world-ending conspiracy in the background, let alone a former-headmaster-possessed child. Yet here he was, leading Beacon Academy into a new age of glory. Or ruin. Definitely a fair chance of the latter…

He was an anomaly not meant to be in this world, yet fate would deem otherwise. After all, the fate of the world just may hang in the balance.

Issei Hyoudou is the Sekiryutei. Not many people knew how powerful he is, or what he's done. And he's perfectly fine with that. He's done with people. All he wants to do is sit back, relax, and watch porn without being bothered by school or homework or devils or fallen angels or annoying conspiracies and why the hell won't they just leave him alone already! Perv OP Issei Harem.

Sea Kings, sea-sickness, sunburns, a 95% genocidal Navy and more than a million and one other assorted ways to die. It's official: Being inserted into an anime sucks ass... Buuut I guess it could be worse. I mean, look on the bright side: At least I'm sailing with the future king of the pirates. (Self-Insert)

Even the Gods and Goddesses of Olympus needed a day off. Sometime's they needed time away from the constant bickering and never-ending controversies of their family. On one such day, Wisdom and Moon found themselves discovering a hidden gem within the city that never slept, and meeting a familiar blonde knucklehead with a penchant for the colour orange.

He was a hopeless man, a man who would amount to a little more than a fool. Yet this man pursued an endless dream, a dream in which he could hold her again... (A Shirou medieval Britain Fic-beginning before Saber drew Caliburn)

Time travel, based on the Anime. So, the world ended. That's bad news. Who best to get to fix it? Well, there is this guy with a track record in world saving... Not entirely serious. T rating may be overdoing it.

As Shirou was dragged into the hole left behind by the grail, the grail itself reaches out to him, acknowledging him as the true winner of the Fifth Holy Grail war. His wish of becoming a Hero is closer to being granted than he originally thought. Now in a world where being a Hero is a feasible profession, will he become a true ally of justice?

Constant Akuma attacks have created a far more strict school system, one that uses corporal punishment. And a new principal who doesn't think twice about taking advantage of it (especially on the girls) makes Marinette's already chaotic life even more difficult. All characters are eighteen and up. This Spankfic. It contains spanking. Don't like, don't read.

With his final breath, he destroyed the Holy Grail. Devoid of purpose after discarding his ideals, he laid down to die. Through the work of fate Emiya Shirou does not die, but instead awakes in a new world. Now, he who no longer wishes to be a hero will have to forge his path once again in a world in need of heroes.

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

Hitsugaya Toushiro is in another sticky situation. He's stranded across dimensions without a way home, and he'll do anything to return - even turn to crime. But the UA and a kind green-haired boy won't let him side with the villains, no matter what happens. Because every broken soul deserves healing and Izuku is just too good for this world. Post-TYBW War, PTSD. Slow updates.

Look, he didn't ask for this. He just wanted a date. And while it was fortunate that he saw a girl's breasts, the burning hole in his stomach wasn't really worth it. And now he had to deal with sexy girls trying to kill him, from God knows how many fantasy species. Actually God's probably clueless about that too. Immortality must have some perks... right? (Cover Image isn't mine)

When Shirou destroyed the Grail, he wasn't expecting it to grant his wish anyways by turning into a rocket and spiriting him away. In a new world, filled with monsters called Grimm and superheroes called Huntsmen, he's finally able to pursue his dream to become a hero! Of course, Grail-kun isn't going to make it easy for him. Semi-serious Carnival Phantasm crossover!

Gaia had, at last, slain Alaya but has yet to achieve victory. In its last cry to save humanity, Alaya spreads its dying embers all over the globe. Emiya Shirou is one such fragment, an incarnation to Alaya's expression of Blade. But as the fires of the Fourth War wash away this aspect of humanity, what remains of Shirou? (Contains some original lore, Predator!Shirou)

Forced to admit that Crocea Mors didn't feel right in his hands—no matter how he held it—Jaune Arc struggled to overcome this obstacle through the insane idea that Aura could become more than just the armor that protected him. Barriers broke as he pushed past the limits of what Aura was capable of, creating and forging his very own weapons from the manifestation of his soul.

Jaune was only worried about two things in life; graduating from high school and dodging his hated bully. He didn't care about the supernatural, nor believe in it. But a chance encounter with a mysterious girl in red will open his eyes to a world that lives beside our own, a dangerous and deadly secret. But beware, child, for eyes once opened to the truth may never again be closed.

No one likes self-inserts. Never knew why. So imagine my surprise when I die and am given the chance to continue living with a new life on Remnant. And with what I know of what's to come, should I try to stop it? CAN I stop it? Or am I in over my head? Well...there's only one way to find out. Time to see what all the fuss is about. (SI/OC) (Colt/?) (DISCONTINUED; REWRITE IS OUT)

If you think about it, self-inserts are technically a form of Isekai genre written by the fans. Depending on the work used. In this case, the work is RWBY. When he dies and is sent to Remnant by two deities with a seemingly impossible task, the Protagonist must tread carefully. Lest he find himself fighting both Salem AND Ozpin. "Oh well...time to be an Isekai Protagonist." (SI/OC)

Izuku Midoriya thought he didn't have a quirk. Deciding that if he couldn't be a Hero in real life he would do it at the table, he sets out on a journey as the worlds one and only Gamer.

The first Fate/Stay Night-Campione! crossover. A Heavens Feel Shirou finds that himself and Illya have been pulled into another world by a corrupted Grail. There his actions lead to him becoming the Eighth god killing Devil King. Now he has to deal with becoming someone who rules where he walks, even if he doesn't want to. That and trying to find a way back home.

Nagisa could've been the God of Death, but as he looks through the classroom the answer is clear.
