Summary
"I despise of many things but...I despise you the most, All Might"
After a life-changing incident that leaves his image of hero society askew, he takes matters into his own hands.
Even with a quirk that wasn't all too powerful in it of itself, he still made heroes struggle, unable to figure out just who he is.
He somehow always knew their next move, but why?Was it his quirk or just his sheer intelligence...?
He became the heroes' biggest problem, yet remained unknown.
Just who was he...?
No one would ever believe it was a mere 15 year old.
Or a high schooler that had been attending the most prestigious highschool in all of Japan...So what did they do when it happened to be the case?

Summary
Yuri gave a lonely child a teddy bear once, then spent years avoiding what he became. After the Chunin Exams leave Suna vulnerable and Gaara improbably becomes Kazekage, her alchemy kekkei genkai and sealing expertise make her essential to the village's survival - which means working closely with the boy who never forgot her kindness. Rebuilding a desert village and navigating intelligence missions is complicated enough without confronting a shared past neither of them knows how to talk about.
[An OC-centric fic set in Sunagakure. MC specializes in alchemy kekkei genkai (pottery/ceramics) and sealing ninjutsu. Features intelligence squad missions, agricultural innovation, village politics, and slow burn Gaara/OC romance. OC is not a reincarnation or self-insert.]

Summary
As they passed a few initiates, he took a breath. They were in front of the door, waiting to go in, when he felt pure dread slide down his spine. The feeling was similar to trying to wash off melted rubber from gloves, sticky and slow but uncomfortably slippery at the same time. Before he could tell Mace about this, however, he ignited his ‘saber and opened the door.

Ponds isn't supposed to be special. None of the clones are. But it turns out the Force has a sense of humor.

Summary
"There is a reason why Ahsoka Tano, former jedi padawan, always wore some fashion of skirt or dress as part of her daily clothing. Looking at her slender and almost frail-looking body—her perfectly smooth orange skin fated by her Togruta ancestry to remain forever hairless—one would never expect to find, upon lifting said skirt, a massive bulge barely constrained by her specially tailored panties."
Ahsoka Tano has a secret she has been hiding for years, one which she might not have to hide anymore after leaving the Jedi Order. Perhaps she should go out on the streets of Coruscant and try and have some fun? In the process, she might even encounter an old friend...

Summary
Izuku Midoriya didn’t expect to be the first human to make contact with an alien species. He also didn’t expect that contact to be an immortal, shapeshifting sex alien named Shoko Todoroki from a six-billion-year-old species devoted exclusively to using the powers of gene editing, shapeshifting, and sloppy breeding sex to create a universe of eternal xenophilia, but hey, it’s a little hard to argue with an immortal shapeshifting sex alien who wants you to fuck every hot girl you’ve ever met, and a bunch of hot alien women she found along the way.

Summary
She is aware with a sudden terrible clarity, that she has received an Uchiha family heirloom.
She slumps at her desk, swearing as her face falls into the palms of her hands.
She screams into the cage of her fingers, elbows sliding forward. The patient files Tsunade had asked her to review, towed by her frustration – near the edge of her desk. Sakura stomps her feet. The heels of her boots beat the furious staccato of a war-drum. She has had it with that stubborn-ass Uchiha who refuses to accept a two-letter word as a valid answer.
The conceited prick.
Their shared history does not mean that they should be dating.

Summary
Damian Desmond, a well-known senator has a meticulously structured life. Every hour is scheduled, every habit controlled, every emotion restrained. The only unstructured part of his routine is his law mandated therapy sessions, though even there he maintains a carefully measured distance.
His composure completely shatters when he receives threatening messages containing explicit photos of himself with a woman from a one-night encounter, the very same girl from his past—who once meant more to him than he ever admitted. She had disappeared from his life eight years ago, but resurfaced briefly two months earlier, spent a single night with him, and vanished again the next morning.

Summary
To him, it was always Min-su. Min-su before everything. Min-su before the job, before sleeping, eating and drinking. If Min-su got plagued by the nightmares, full of blood and gunpowder and fear, Gyeong-su would've sacrificed his own sleep to ensure Min-su could at least close his eyes that night. He was no martyr for that, and these weren't really sacrifices. Compromises, of sorts. One night, it's he who's guarding his lover's sleep, the other night it's Min-su. Easy as that. An agreement that needed no words to be made, sealed with a single look in the eye and a tender kiss pressed to a wrist.
A story of a sword and a shield, of the one who sees and the one who is seen.

Summary
“President, as much as I respect you and your authority, I don't believe it to be a good idea for those two to be sent on a mission.”
“And it is partially for that reason that you will go with them.”
“We can't afford to lose three agency members at one time. How important could this possibly be? The agency will be losing three of its members for nearly an entire year. This doesn't work at all with any schedule we could figure out. It will be pure chaos!”
“It could be the potential downfall of Japan if not more of the world.”
With a sigh Kunikida took the folders from the Presidents’ desk. “I will go meet with them, when shall we leave?”
“The sooner the better, hopefully today.”
