Summary
Mastering the art of Fuuinjutsu was the natural path for Iruka. It was the jutsu that the Fourth Hokage used to save his village from the demonic Nine-Tails. Investigating Konoha’s restrictive archives leads him to gain the Tenshigan, allowing him to see the once invisible forgotten ghosts, terrifying spirits, and sadistic demons walking the world and seal them within himself. However, Iruka’s struggle to control these forbidden powers may have cursed himself and his village.

Summary
In which Sakura goes back in time - but it is to the exact moment when her newly appointed sensei opens the classroom door and a chalk-covered eraser falls on his head.
How do you save the world and your loved ones when they’re constantly breathing down your neck? Did her sensei always have nothing better to do besides meddling in others' business before the war? Was her former academy teacher always this perceptive? Had her home always been under the order of such evil men? And…did no one else see the ghosts or hear the trees?

Summary
“Oh, for fuck’s sake.” Iruka smacks a hand against his cheek, feeling rough fabric under his touch. He runs a finger along it, confirming that it covers the bottom half of his face and hooks behind his ears (undoubtedly a medical mask), and then turns his head to where Tsunade is watching him with crossed arms. The movement causes a strand of silver hair to fall into his face. “Where the fuck is Kakashi?”
“Funny. If I were anyone else, I would’ve gotten the impression that I was talking to him.”
(or, iruka and kakashi swap bodies, iruka sees ghosts, dies, comes back and naruto has several mental breakdowns. not in that exact order)

Summary
Kakashi has the vague idea he should be doing something to take care of Minato-sensei's son. He should, right? Maybe get him some kunai? Or shuriken? But when he goes looking for the kid, he finds out the chuunin he said couldn't cut it is already taking care of him. Or trying to, anyway.
Iruka and Naruto share some history; Iruka tries to teach him how to take care of himself, and Kakashi offers the only thing he has to help out.

Summary
“Some rules are too stupid to be followed. If I followed all the rules, I would now be an apprentice carpenter as my parents wanted me to and wouldn’t have met you.” Jiro shrugged back at Naruto. “Also, if you followed all the rules you wouldn’t do all the pranks and life would be too boring.”

Summary
Інколи здавалося, що Ірука завжди був поруч, навіть якщо на периферії, на безпечній відстані. Він також знав, що із кожним днем усе важче було віддалятися, відводити погляд.
Тому, мабуть, добре, що Ірука зробив це першим. Швидко і майже безболісно, понизив його від усміхненого “Какаші!” до “Чим можу допомогти, джьоонін-сан?”. Стер упевненим рухом їхню передісторію.
Або: близьке до канону АУ, де Учіха отримують шанс, розмова на лаві про хлопчика-джінчюурікі відбувається раніше і - уважно слідкуйте за тим, кого записали у слабаки. Усе гірше, ніж здається.

Summary
When rumors surface about a lost forbidden genjutsu, Kakashi is sent to investigate. But it’s a trap. Captured by rogue shinobi, he’s subjected to relentless torment, both physical and psychological. Wounds heal, but scars remain; something fractures, far deeper than they realize. As the lines between illusion and reality blur, one question remains: what becomes of the Copy Ninja when the man beneath the mask is irreparably changed?

Fantastic start of the week if she says so herself.
Kujira Hatake somehow found herself in the past, will she be able to make it home? and how will she react to seeing her parents so young?

Summary
Attachment is not a good trait to have for a shinobi. Infatuation is an even worse one, a miniscule but potentially fatal character flaw that has the slim but not-inexistant opportunity to get in the way of duty one day in a manner that can't be undone. Lucky for Iruka, who doesn't seem to have this problem, all this is or has ever been between them is just really phenomenal sex. Obviously.

Summary
Umino Iruka is off on a new C-Rank mission. He really hopes he can avoid getting injured this time, or at least stay out of his genin team members' way long enough to be helpful. Finding himself trusted with even more confidential information, Iruka's beginning to wish he wasn't. It seems that seeing too much can be as much a curse as taking on a mission sight-unseen.
...are all of Konoha's kekkei genkai monstrous, or is Iruka just unlucky enough to encounter the worst of them one after another?

Slice of life fic that features exasperated older brother Asuma.

Summary
Every year during Golden Week Iruka finds himself waking up to strange dreams that always feel a bit too real for comfort. Smells, sounds, sights; sensations that make him feel like it's not just an accumulation of stress fabricating a crazy world where Hatake Kakashi was his true mate. Him. A beta.
Doesn't help that the waking world isn't much better, with a weird mood and an even weirder Hatake Kakashi making it feel so much stranger.
