Chapter Text
“The difference between poison and medicine is only a matter of dosage.” Izuku Midoriya said, tapping the syringe as he pocketed the empty vial and looked down at the bruised and bleeding teenager, his jackboot on his throat as he knelt down and increased the pressure.
The young man wore an ancient MRS mask to match the trench coat which completed his ensemble. He couldn’t speak as his eyes locked with Izuku’s who grabbed him by the throat, rubbing his thumb along the carotid artery, the nameless youth could not speak or move from the dendrotoxin dart he had shot him with earlier, only eyes flickered begging for mercy wordlessly.
Izuku didn't need to hear the words in his mind to know he was pleading for his life but he knew that things were too far gone as he stuck the needle into the artery, looking away as he pushed down on the plunger and pulled out the needle, shivering as he capped it and put it back into his pocket for safe disposal later as the pupils in the young man’s eyes dilated and his cocktail took its effect as they went glassy and he waved his hand over them to close them then placed both of the young man’s hands over his chest, leaving a blue rose between them.
The purple fog lifted within minutes and the sirens in the distance grew louder as he heard footsteps from behind yelling out. “We gotta leg it!” before he fell over a body, yelling as the thinning purple fog revealed the horrors it was hiding in the busy mall.
Women, children, men by the hundreds lay dead, all of them blue in the face with varicose veins jutting out in the last moments of hypoxia brought on by the asphyxiating nerve agent they had been exposed to. It was not fast and it was not painless when their lives were taken as their corneas had gone milky.
“Whatever’s in the beyond… I hope it’s better than this.” Izuku grabbed his partner roughly, pulling him to his feet with a coldness in his voice through the rebreather. The sirens in the distance were closing in as he looked over his protege in the dim light as he raised the radio and pressed the button, “Curtain Call Gateboy.” he said before turning it off, knowing the signal would soon be traced as he pocketed it and shook the shivering teenager with both hands.
“I Used to think nothing was colder than death, now I know different Kastuma.” Izuku said more harshly stopping him from looking around at the death that surrounded them. Midoriya's tears pooled in his eyes shook violently as they traced down his cheek, looking at the red haired boy, scrawny as a wire, despite being 15 looked much younger because of his babyface. He wore plain jeans and an All Might shirt that Midoriya had long outgrown, his own rebreather mask an older model as he looked back at him, raising a hand to wipe the tears from Midoriya’s cheek but his hand was swatted away as they heard a hum followed by a short plasmatic burst that ruptured the air around them like a bubble.
The dome widened and a crackling portal opened in the ground below them, its stability in doubt as arcs of plasmatic energy licked the ground, charring bodies it arced on. The sirens had died down as the cars were now parked Midoriya and Katsuma fell through it. A concussive shockwave blew a strong gust of wind in all directions as the portal snapped shut like a rubber band and the cops ran into the atrium by the dozens.
A greyed Tsukaichi who had reluctantly taken on the role of Captain at the ripe young age of 40 looked around at the bodies, scanning them for the tell tale calling card. One of his men yelled for him, waving him over for the exact thing he was looking for as he snapped on an elastic glove and rushed over the bodies, careful not to trip over them as he saw the young man in his trenchcoat and M2 mask holding the blue rose.
“That’s the twelfth one this year sir.” the nameless officer said as Tsukaichi picked up the blue rose. He had collected hundreds since the last decade, never wilting, everlasting, freshest scent even from the first rose he had collected when the killer had come on the scene.
“Kei bagged another one.” he lamented, studying the rose, he had committed hundreds of them to memory that every detail was a facsimile with no deviation from each other, it was as though they had been made in a factory rather than grown, a marriage of nature with the precision of industry.
“Sir he was just a kid.” the officer said somberly as he took off the M2 mask, horrified to see the blonde young man. “Weren’t they?” Tsukaichi clicked back as he waved at the hundreds of dead children in the dim atrium, and the officer looked away. “ “Precision is the difference between a butcher and a surgeon.” Tsukaichi said as he rolled the rose by the stem between his fingers and bagged it to add to the case files, letting the officer chant his prayers as he turned around and sighed.
This quirk singularity had been canceled today but at what cost, Tsukaichi thought to himself as he handed over the bag to his forensic team who were in discussion with each other over their findings. He had been chasing Kei for a decade but his victims had always been quirks that had gone out of control. Wondering if the police had to handle the hundreds of kids he put down, how would they have handled it any better as he looked up at the waxing moon that bathed the atrium in a macabre light that radiated the gloomy scene.
