METEMPSYCHOSIS -Trigun

It takes place in trimax up until it doesn't

Or, a quote from the story
"The morning of the day Vash dies isn't a particularly special one, not compared to the mornings he's spent startled out of sleep by gunshots or attacks. There's nothing special about the day, no anniversaries of particularly tragic deaths or events, no holidays or birthdays. Not even the weather was notable that day."

Reincarnation AU where when Vash eventually dies sometime post manga he gets reincarnated into Tristamp

Includes:
-DAILY UPDATES!! Yay
-Pre-canon, little character mentions besides Knives appearances
-Manga spoilers
-Trans Vash
-Some Milly mentions(she does not exist in tristamp)
-(Vague)Depictions of violence
-DIY top surgery in the way that they're on a desert planet
-No explicit Stampede spoilers, but that's not much when it's still at least vaguely based on the manga, which is totally spoiled basically for all the main points

This was posted as a oneshot on my Ao3 but I've been starving you all so I broke it up and am feeding it to wattpad in order to spread my silly agenda, have fun <3
