So May turned into my biennial swing through Naruto fandom (have I ever seen a single episode? nope), during which I managed to fall down the Madara/Tobirama rabbit hole - which is a very fun time if you enjoy extreme competency and enemies-to-lovers! Also I've got some Kakashi/Iruka fic, and a couple of Guardian fics for Shen Wei/Zhao Yunlan. More recs at Pinboard as well!
NARUTO - FOUNDERS ERA
As Is the Sea Marvelous by blackkat
Tobirama is willing to give absolutely anything for Hashirama and his dream.
AKA the fic that started me down this rabbit hole. Blackkat is so dangerous with the gateway drug fics like that - this is a great canon AU aimed directly at my id where Tobirama surrenders to the Uchiha in hopes of stopping an escalation of the war after he wounds Izuna.
and all the fire's at your fingertips by pandaflower
Tobirama is elbow deep in a stealth mission in Wind Country when he runs into a shinobi squad toting a stolen Uchiha child. Tobirama disapproves.
Charming gen competence porn/kidfic adventure.
With Enemies Like These by sarkasticfics
After a serious and devastating attack, the Uchiha are in desperate need of a sealmaster. Unfortunately for them, the best candidate happens to be from the Senju clan. Fortunately for them, he doesn't seem all that inclined to act like an enemy.
Which is lucky because, as it turns out, there are plenty of other adversaries making moves in Fire Country - both the clans will need to make new friends to survive.
Madara would have been content if his new husband tolerated him and helped his clan stay safe. He doesn't quite know what to do with the fact that his husband doesn't stop there.
Jam-packed with competence and tropes, just the way I like it - and there's some incredibly lovely moments as they reconcile with their clans' bloody pasts.
Count Your Blessings by madmothmadame
The war is over. Tobirama ended it when he put his sword through Izuna's center mass. But where war had united the Senju behind their leader, peace threatened to tear them apart. And who better for the warmongers to look to as a leader than the greatest killer of Uchiha they had ever seen?
There were only two problems with that plan. One, Tobirama would never, ever, betray his elder brother.
Two, he may or may not have a surprisingly not dead Uchiha Izuna in a coma in his guest room, hiding the secret of resurrection that Tobirama needs with everything he is.
Now if only he would wake.
Deliciously epic. The inciting incident is very hand-wavey (having been inspired by another fic), but the follow-through in worldbuilding around Konoha's founding, the metric truckload of feels, and the twisty political intrigue makes for a great read. Be warned, there's like 250K of hurt before it gets to any sort of comfort, so maybe save it for a long rainy day if you don't want to suffer (like me). Also, the ship is pretty background, so don't expect much romance - but the gen relationships are fantastic and crunchy.
NARUTO - CANON ERA
for the record by ohwickedsoul
Asuma looks from Anko, who is laser-focused in a way rarely seen outside missions, and Iruka’s bewildered face.
“Holy shit,” he says. “You’ve seen Kakashi’s face.”
The ending is TRUE ROMANCE, OKAY. And hilarious!
It's Amazing Who You Stumble Into (along the road of life) by vulcanhighblood
Hatake Kakashi and Umino Iruka have been part of each other's lives for a long time. A lot longer than Iruka realizes, anyway. Kakashi recognizes this is something of a problem, but only once it's too late to do anything about it.
OR How To Make Your Secret Identity Friend Your Real-Life Boyfriend: A Shinobi's Guide To How Not To Romance
In which they keep running into each other over the years, complicated by Kakashi being ANBU for the first half of it. I loved the varied assortment of meetings, and the way they kept trading off on helping each other (physically, medically, emotionally).
GUARDIAN
Breaking Point by musicalluna & nightwalker
Zhao Yunlan is having a really terrible week, and it just gets worse when he starts to think Shen Wei has gotten tired of his bullshit.
Fantastic post-canon piece where the boys really need to communicate, and the universe/work is not helping. Excellent characterization and some brutally good relationship fights - but they figure it out in the end.
However deep the Lake by elenothar
Zhao Yunlan finds out a lot earlier that the Envoy isn't as invulnerable as he seems.
Classic h/c story where they're taken captive together in Episode 4.
