Poe is a vampire. Not Bram-related, no, he just has literal vampirism.
Ranpo (+ the perfect crime guy, + the Guild, and/or maybe + the rest of the ADA) figure this out in the funniest way possible.

Not one of those in the cinema, God knows how much he hated Twilight, but a true, actual vampire.
He burnt in the sun, required blood to survive, could turn into a black cat (and a bat, but he truly preferred to be a cat), and would die if he was near silver.
Crosses, he could handle. Thankfully. And most of the blood he drank could be substituted via animal blood or donated blood (even though it tasted starchy and cold when he knew it was supposed to be warm).
Of course, no one else knew.
God knows what would happen if they did. The Guild, well... that wouldn't be too much of a problem, given how Lovecraft was... something, and everyone else seemed to simply figure out ways to ignore the creature's otherness. So they would more than likely simply find ways to work around his inhumanity as well.
Though he would rather not risk it.
It was more his dearest Ranpo he was worried about.
Ranpo's blood sang to him, as if begging to be drank, and Poe just knew it would taste like the sweetest wine man had ever known if he sank his fangs into his dear Ranpo's neck and simply drank. (Perhaps it was because of all the sweets Ranpo constantly ate.)
But of course, he knew better. And if he ever saw Ranpo with those intentions, Poe has no doubt the younger detective would know the instant the older of them walked into the room.
The way Ranpo truly found out about Poe's... condition was positively stupid, if Poe did say so himself.
Apparently, those retched Twilight movies, all 4, had been dubbed over in Japanese. And were being shown back to back in theatres. And Ranpo wished to see them because... well, Ranpo didn't truly know why, but didn't question it. One could simply wish to see a movie with their dearest rival without having ulterior motives. And of course, Mushitaro (or as Fitzgerald called him, Kilimanjaro) got dragged along as well, for some reason or another.
Poe payed for everything, of course. It was only just. He had the most money out of all three of them, and so it was only fair that he payed for his own torment, he supposed.
The first movie was agony. The second was torture. The third was practically a war crime. Poe practically dissociated with the fourth. They were all so... inaccurate. And bad. And just plain awful.
Poe would have rather step into the sun without a parasol than watch those... monstrosities, again.
And so, reasonably, after nearly 8 entire damn hours of watching those godforsaken movies, he was at his wit's end. So when Ranpo asked him what he thought of the movies, he had perhaps... snapped.
"They're awful! They're so awfully inaccurate its nearly offensive! Everyone knows vampires burn in the sun! Hell, if I could go in the sun and just sparkle instead of what, burning alive, I would be at the beach every day of my life! And God above, what is with all of them having super strength?! My bones would have broken if I attempted anything of the sort! Where are the transformations?! The actual lore?! Vampires are practically infertile, everyone knows that! We reproduce via bloodborne contact, not through whatever happened in that 4th piece of-"
Poe stopped himself, realizing Musitaro was staring at him in both confusion and... probably annoyance, while Ranpo himself looked vindicated.
Without missing a beat, the young detective turned to Mushitaro. "I told you he was a vampire! See! My Ultra-Deduction is never wrong!"
Mushitaro scowled. "Did you actually expect me to believe you at first? You burst into my apartment and begin claiming that Poe is a vampire, despite Poe getting squeamish at the sight of blood. You sounded insane."
"And you doubted me. And you were proven wrong. Obviously."
"You truly are both so damn insufferable."
Poe blinked. "You... knew?"
Ranpo grinned. "Obviously! You're really obvious, you know? Now those movies were awful. I need at least... 2 bags of candy to make up for it."
Poe smiled faintly. "Of course, my dearest Ranpo."
