Summary
Indiana sounded like a nowhere kind of place. It sounded like the kind of place that could be quiet, obscure.
Indiana could be where Sirianna Lily Potter keeps her brother, Harry James Potter, safe after the torment they suffered at the hands of the White Coats.
Except, with twice as many Potters, there was twice as much bad luck at play. Instead of finding a normal and small town, it seemed as if the small town had found them. And there was nothing normal about it.

Summary
A self-professed workaholic, Auror In-ho's life is straightforward: catch dark wizards, file paperwork, make sure his prickly best friend hasn't hexed anyone he shouldn't have (again), eat, sleep, repeat.
Everything changes overnight.
Raising a little wizard, even one as sweet and adorable as his six-year-old brother, is NOT for the faint of heart. And just when he's gotten the hang of things, everything changes overnight. Again.
Enter Seong Gi-hun: charming, competent, captivating, delightfully witty, and best of all, is adored by & adores Jun-ho.
For In-ho, it's love at first sight. Now he just needs to find a way to make the epitome of Wizarding Perfection a permanent fixture in their chaotic household. Easy, right?
...
** Cue one smart, sassy little wizard + his beloved Mister Salesman-hyung (who just so happens to be In-ho's best friend) to the rescue

Summary
Everyone and their mother knew Crime Alley sat on a razor's edge- only one slight imbalance away from toppling over, just the barest of embers away from fully igniting. The Bats felt for the residents there- worried for them and helped where they could- but full involvement was too dangerous. (Red Hood didn't give three shits about danger. Crime Alley was his home and if he had to burn it to the ground to make it better he would- and Bats be damned: he did)
Every member of the Justice League knew that The Founders Community was on the verge of another civil war- coexisting never seemed to be in their vocabulary. The situation was monitored of course, but no one wanted to be the one to pull the trigger on one of the largest meta communities in the nation. Fanning the fire would only invite death. (Hadriyan 'Rin' Black had been friends with death since she was an infant, she didn't give three shits about inviting the bastard over for tea. Death was already at home in the Founding, and if she had to lead a civil war to get the rest of the world to see it she would. In doing so, she saved hundreds- if not thousands- of lives)
Now: if only Hermione could get the two red-clad idiots to realize they're in love.

Summary
Just to clarify, this is just another idea that I hope will inspire someone to write a fic for me to read ♥️
What would happen if an OC of Naruto, a former Hokage, was reincarnated in the Harry Potter universe? Well, then the wizarding world would see what a paper-nin (a medic-nin and a master of seals) could do when his Will of Fire is put to the test.
A war against a megalomaniac and his private army? This seems more like a deja-vu from Danzo (may he rest in hell). No matter the world, it seems that Lyra will always have to be the one to take out the trash.I made an English version (it may take longer to update than the Portuguese version) with the same title (https://archiveofourown.org/works/59432233/chapters/151566286#workskin).
