Summary
“Did you know that the skies are fake?”
As a nine year-old former Khaenri’an prince, Kaeya knows many things they really shouldn’t. About Gnoses, for example. Their future adoptive family, for another. About the curse that has befallen their people, the secrets of several archons, the birds and the bees, the future of Teyvat as a whole... all thanks to their memories of a past life where they were a hot mess of a college student who had no idea what they were doing and played a certain popular gacha game.
Kaeya still has no idea what they are doing, and this time lives are riding on their decisions. As things stand, their adoptive father is doomed to die on their brother’s eighteenth birthday. So they have to figure out how to prevent a premeditated murder via Fatui Harbinger within eight years, while also hiding nearly every core facet of themself for their entire childhood - because Kaeya is so fundamentally terrified of rejection that they cannot reveal their true self to anyone. Not even the people they love and trust most.
Time does not heal all wounds. Not without proper treatment - and Kaeya, who never lets anyone know them in their entirety, has left theirs to fester.

Summary
Where I will post snippets of self-inserts that are just plot bunnies I can't shake or entertaining enough that they have been officially cleared to leave the deep, dark recesses of what most people will call a 'Google Docs'. This depends entirely on my mood and current fandom of obsession, so some may be single-scene one-shots while others might be vaguely continuous.
The Latest Shitpost:
(Detective Conan)
Shinichi hovers over the body. It’s been hours and it hasn’t stirred. Shinichi isn’t sure if it ever will. It feels weird to call the child lying on the ground an it, but that’s... basically what it is.
Because that’s Shinichi’s body. Ghosts are apparently real, because Shinichi is one now. Somehow, the poison he was force-fed had shrunken his body on top of ejecting his consciousness from it. His body, which is somehow still breathing despite Shinichi not being attached to it.
Then the security guards arrive, and his body wakes up.

Summary
The thing about being a teenaged superhero is that no one ever tells you how much it sucks. None of them would trade the friends they’d found in each other for the world, but it’s unbelievably stressful. Having to keep a secret identity while trying not to flunk out of school is already bad enough. Add on the fact that not even your teammates are allowed to know your identity, your supervillain being able to turn you against the city if you feel too much negative emotions about anything, and his ability to read his victims’ minds?
The heroes will be lucky if they defeat Hawkmoth before any of them graduate.
(Of course, Kaeya already knows his brother is the famous Ladybug hero Scararouge. Really, only a Ragnvindr could pull off that shade of violently red hair.)

Summary
For all my time travel AU's, reincarnation/transmigration-type crossovers, and basically anything that falls under the umbrella of time travel or dimension travel. And just crossovers in general actually.
Current Destination in Spacetime:
(Kimi ga Shine / Genshin Impact)
The Eleventh Fatui Harbinger lies before him, unarmed and completely defenseless. The red key Xingqiu had used to unlock his own restrains weighs heavy in the palm of his hand.
A bitter expression crosses Childe’s face. His empty blue eyes bore into Xingqiu’s very soul. “Ah. So you’re going to let me die.”
Xingqiu’s hands curl into fists. The edges of the key dig into his palm. “I didn’t say that.”
“I can see it on your face, comrade. You’re considering it.” Childe smiles. Xingqiu hates it. He’s seen a plethora of fake smiles from the Harbinger before, but even those had some kind of substance to them. The smile on his face now is just... empty. “I can’t say I blame you.”

Summary
Life as Gamzee Makara isn't exactly the happiest one. It's certainly not the worst, but- it's not great. It doesn't help that they're wholly unaccustomed to the merciless brutality of the Alternian lifestyle, too used to the idyllic peace of a suburban Earth town.
Most trolls are hardened by their harsh circumstances. Violence is natural to them, because they have never known anything else. Gamzee has. They know the world can be better - have lived in a world where things are better - and that makes it difficult to cope.
And as if that weren't enough already, the imminent Doom of the timeline looms over their head - their very existence threatens the lives of everyone they have ever known. If they don't keep things the same, their timeline will diverge from the Alpha and everyone will die. And they will have no one to blame but themself.
No matter how desperately they wish to, they can't save everyone. It's all that Gamzee can do to preserve the livelihoods of the few who are destined to survive.

What it says on the tin.
AKA: somewhere for me to gather all of my posted self-inserts in one place, because i'd never be able to keep track of them all otherwise. (I really need to start branching out into other genres that aren't my well-worn niche of obscure self-inserts lmao.)

Summary
Technically it was the church’s job to make sure the multitude of vampires in Mondstadt were well fed and not about to go feral from starvation. The knights were to step in only when the situation had escalated and a rogue vampire was in need of emergency feeding or worse.
But Kaeya liked to think he was preventing problems before they started
When a new Vampire in town doesn’t eat for a dangerously long time, Kaeya takes it upon himself to prevent a vampire attack.

Summary
"A contract?” said Venti, “Did you just lock me, god of wind and freedom, into a contract?”
Somewhere between the first glass of wine and the last, between a solemn oath and an offering to a god, Venti gets bound in a contract to protect and care for the last of Alberich line. Sure 1000 years ago Venessa had banned him from babysitting, but he can handle this freshly traumatized seven year old.
Crepus would beg to differ. He takes one look at this “irresponsible alcoholic teenager” playing parent and decides he needs to step in.
OR: Papa Alberich gets lost and ends up leaving Kaeya with a friendly bard instead of at the winery. Venti adopts Kaeya…and Crepus adopts them both.
OR: The Anemo Archon, a Khaenri’ahn spy, and a Fatui Harbringer all think they have figured out what is going on but they are all playing very different games.

Summary
Iruma is human. This means a lot of things for him, being the odd one out amongst the demons around him. He doesn't have horns, fangs, or a tail- but it's easy enough to dodge questions about those. Maybe it's unusual to be missing all three, but there's a large variety amongst demons. What's harder to explain away is his lack of wings, which he had been doing so well at hiding...
Except- humans are mythical creatures, to demons; so when Iruma's missing wing roots are discovered, that's not the first thing on anyone's mind. There is, in fact, a reason that a demon might be missing their wings. A horrible, horrible reason.
Never before had Iruma been grateful to have his scars.
