Summary
It was sudden, small. Just five names disappearing from a list.
It’s not anymore, not when the world is breaking to pieces. Not when his soul aches with loss, not when it feels like his own flesh has been gouged out in their absence.
He looks, but cannot find.
He endures. He has to.

Or: fWhip’s an admin, but Last Life took his players and his world is falling apart. He’s having a terrible time.

How to Solve a Murder and Incite a Rebellion by Kastaborous

Summary
In unearthing the Nomu Factory, the Heroes and police of Japan discovered a body. This was not unexpected, but the nationality and uniform of the corpse in question… that was. Because this failed Nomu wore the uniform of Amestris, a war torn nation from the isolated continent of Atossa, where Quirks and modern electronics had never developed and never worked.
Edward Elric hoped he could retire from military service in peace, traveling Amestris while his brother Alphonse went to Xing. This is put on hold when now-Führer Mustang asks him to travel to the Outside, to the world beyond that was barricaded for centuries after the development of something called ‘Quirks’. A soldier has been killed and Amestris needs to know more about the Outside.
…
Or, Edward Elric and Amestris meet the greater world of Heroes and Villains. It remains to be seen who’s more traumatized by the encounter.

Summary
Ed had thought, after the whole Promised Day, homunculus, entire country harvested for alchemical batteries thing, the batshit quotient of his life would have settled down some. He really ought to have topped out the meter with that one. But no. The bullshit is just getting started.
“Are you fucking kidding me,” Ed demands. “The wizards?”

Summary
As Truth leaned forward, Ed's eyes burned, and yet, he couldn’t look away, as if he were a fluttering moth to a candlelight. "Yes, yes – now, I want to believe that you are not so naive to think that reality revolves only around your singular, dispensable timeline, yes?"
…What?
Truth only smiled wider.
--
The Law of Equivalent Exchange is bullshit. That's what Edward Elric decides after he wakes up in a dumpster after he makes a deal with Truth in order to save his brother. Aizawa Shouta's list of problem children just keeps getting longer by the second, and Japan definitely isn't ready for the uncontrollable hurricane of destruction that is the Fullmetal Alchemist.
--
Or; a FMA x BNHA crossover fic that I wrote when I was fourteen that got out of hand. Canon divergence where Ed's gate is only enough to restore Al, not keep him alive and well. Obviously the only next course of action is an isekai.
As of 9/29/2026: I am working slowly on a minor rewrite of this fic as well as the next chapter. Thank you all for the patience! :)
