The Musutafu Convention Center was bigger than it needed to be.
Four floors of exhibition halls and corporate-looking corridors that all smelled like industrial carpet cleaner. The Hero Commission had booked the main hall for the quirk demonstration event and the place was packed by the time Riku arrived. Kids his age in school uniforms, younger kids with hero merch plastered over every available surface. Parents trailing behind, looking at their phones. A few serious-looking adults who were probably scouts or journalists.
Riku bought a program from a booth near the entrance and found a spot about twenty rows back from the stage. Not too close. Close enough to see faces. He'd learned from the Mount Lady event: positioning mattered.
The first hour was fine. A series of heroes did demonstrations of their quirks while an MC narrated from the side of the stage. A guy with a stone-transformation quirk bench-pressed a car. A woman with wind generation blew a row of targets off their stands from fifty meters. Endeavor showed up for exactly twelve minutes, blasted a wall of flame that scorched the ceiling tiles, and left without taking questions. The crowd loved it.
Riku watched with the same detached appreciation he brought to everything hero-related. Impressive, sure. But none of it was why he was here.
Then Midnight walked on stage.
Nemuri Kayama. Thirty-one. Six years of pro hero experience. Ranked mid-forties, which undersold her because her quirk wasn't flashy enough for the rankings algorithm. She taught Modern Hero Art History at UA, which he knew, and she'd written two published papers on pheromone-type quirk applications, which most people didn't know.
She was wearing the full costume. The one that had earned her the R-Rated classification and a decade of Hero Commission complaints that she'd ignored with visible pleasure. Skin-tight bodysuit that left very little to the imagination, the utility belt slung low on her hips. A small domino mask that did nothing to hide her identity and wasn't trying to. Long dark hair loose past her shoulders. She walked to center stage like she was walking into a classroom where every student already knew they were in trouble.
The MC introduced her and she took the microphone with a smile that was warm on the surface and sharp underneath.
"So," she said. "Who wants to learn about pheromone-based quirks?"
Her demonstration was different from the others. No explosions, no physical feats. She explained her Somnambulist quirk in clinical terms while slowly, deliberately, releasing her aroma into the hall. Riku could see the front rows reacting before she'd finished her first sentence. People blinking more slowly. Shoulders relaxing. A kid in the second row yawned and looked confused about it.
"What you're feeling right now," she said, "is a low-level exposure. My aroma induces drowsiness and compliance in anyone who inhales it. At full strength, unconsciousness in seconds." She paused. Let the front rows feel it settle. "The reason I'm showing you this at reduced power is because I'd rather not put three hundred people to sleep and then explain it to their parents."
The crowd laughed. Some of them laughed a beat too slow because they were already half under.
She talked about quirk classification and the difference between emitter and mutant pheromone types. Got into the social challenges of quirks that affected people's emotions and decision-making. It was the most substantive presentation of the day by a wide margin and barely anyone was paying attention because her quirk was literally making them drowsy while she spoke. Riku appreciated that.
He was sitting twenty rows back and he could feel her aroma at the edges of his awareness. Faint. A warmth in his sinuses, a softness at the back of his skull. His body recognized what it was encountering before his brain caught up. Pheromone-type meeting pheromone-type. His Allure Aura stirred in response, reaching out toward her signal like a radio antenna turning toward a broadcast.
He clamped down on it. Hard. Pulled his control as tight as it would go, which right now, fully fed, was very tight indeed. His aura compressed to a meter around him, almost nothing. But the interaction had already happened. His quirk had pinged hers and hers had pinged back and the exchange had taken less than a second.
On stage, Midnight stopped mid-sentence.
She covered it well. A professional pause, a sip of water from a bottle the MC had left on the podium. But her eyes swept the crowd. Nothing to do with her presentation. She was scanning. Looking for something she'd felt but couldn't see.
Riku sat very still in his seat.
Her aroma shifted. He felt it happen, a change in the frequency of it, like a radio dial turning. The drowsiness component receded and something else took its place. Not sleep-inducing. Searching. Her quirk was reaching out into the crowd, probing, trying to find the signal that had responded to hers. Follow the newest chapters on novelping(.)com.
She didn't find him. His control was too tight, his aura pulled in too close, and twenty rows back in a crowd of three hundred people was too much noise for her to isolate one frequency. But she knew something was out there. He could see it in the set of her jaw and her presentation shifting from clinical to slightly distracted for the next five minutes.
She finished her segment. Took questions. Answered them with the easy authority of someone who'd been teaching for years. But between answers, her eyes kept sweeping the back rows.
Riku didn't move or react. Didn't make it easy. Same play as Mount Lady but for different reasons. Mount Lady he'd let the aura touch and then walked away. Midnight he was keeping the aura locked down because if he let it loose in here, in a room where her pheromones were already thick in the air, the interaction would be visible. Obvious. Two pheromone-types reacting to each other in a crowd would look like what it was, and he didn't need three hundred witnesses for that.
The event ended. The crowd dispersed slowly, funneling through the exits, kids asking for autographs, parents rounding up sugar-crashed toddlers. Riku stood up from his seat and moved toward the main exit with the flow of the crowd.
A hand caught his elbow.
"Stop."
Her voice was different up close. Lower, more textured, with an undertone that might have been her aroma or might have been just her. He turned and Midnight was standing behind him, one hand on his arm, her dark eyes fixed on his face with an intensity that the stage persona hadn't carried.
Up close she was shorter than he'd expected. Five-six, maybe five-seven. The costume was even more revealing in person and she wore it like it was a business suit. Zero self-consciousness. Her dark hair fell over one shoulder and her skin smelled like something floral that was layered over something else, something chemical, her aroma leaking at the edges the way his did when he was focused on something that had his attention.
"You," she said. "What are you?"
"Riku Amane. I'm a student."
"That's not what I asked." Her hand was still on his elbow. He could feel her aroma concentrated at the point of contact, a warm buzz that his Allure Aura was straining toward. She could feel it too. Her fingers tightened on his arm. "Your quirk. I felt it during my presentation. Pheromone-type. Strong one. What classification?"
"Incubus," he said. "Emitter-transformation hybrid."
Her eyes changed. Not wider. Deeper. She let go of his arm and took a half-step back, not out of discomfort but to get a better look at him. The full assessment. Head to toe, unhurried, clinical and not clinical at the same time.
"Incubus-type," she repeated. "Those are rare. I've read the literature. Allure aura, vitality drain. The whole package."
"You've done your homework."
"It's literally my homework. I teach a class that covers quirk classification at UA." She tilted her head. "You're what, fifteen? Sixteen?"
"Fifteen. Taking the UA entrance exam in two weeks."
"Hm." She considered him. The crowd was thinning around them, people flowing past on either side, nobody paying attention to a pro hero talking to a kid in a convention center hallway. "Your control is impressive. You pulled your aura in when you felt me. Fast. Most pheromone-types your age can't manage that kind of suppression."
"I've had a lot of practice."
"I imagine you have." She said it without judgment. "The interaction between our quirks. You felt it?"
"Yeah."
"Describe it." This story is hosted at g.com.
He thought about it. "Like a signal finding its frequency. Your aroma hit my aura and they... recognized each other. Resonated. My quirk wanted to reach back toward yours. I shut it down because I didn't want to cause a scene in a room full of people."
She stared at him for a long moment. He couldn't read her expression and he was usually good at reading people.
"Smart," she said finally. "If you'd let that interaction happen at full strength in a crowded hall, the combined pheromone output would have had people climbing into each other's laps." A pause. "The resonance you described is documented in the literature but almost never observed in practice. Two pheromone-types of compatible frequency in the same space. It's rare."
"How rare?"
"Published case studies in the single digits."
She reached into a pocket on her utility belt and pulled out a card. Small and white, professional. She held it out to him.
"My number," she said. "For quirk research."
He took the card. Their fingers didn't touch during the exchange. She'd been careful about that.
"Quirk research," he repeated.
"I have a professional interest in pheromone-type quirk interactions. You have a rare quirk that I've only read about in papers. If you're going to be at UA, we'll be in proximity regularly. It would be irresponsible not to study the interaction." Every word clinically precise. Her face gave away nothing.
"Irresponsible," he said.
"Extremely."
They looked at each other. The convention center was nearly empty now. Somewhere a janitor was running a floor polisher and the sound echoed through the hall like a distant engine.
"I'll call you," Riku said.
"Please do. For research." She turned and walked toward the backstage area. Her stride was measured, professional, the walk of a woman who'd said exactly what she meant to say and nothing more. She didn't look back.
Riku looked at the card. Nemuri Kayama. A phone number. A small UA faculty logo in the corner.
He pocketed it and walked out of the convention center into afternoon sunlight. His Allure Aura was humming at the edges of his control, still reaching toward the place where her aroma had been, chasing a signal that was already fading.
Two pheromone-types of compatible frequency. Published case studies in the single digits.
He smiled and started walking toward the train station.
Twelve days until the entrance exam.
