Chapter 18 : Trigger Theory
The engineering database terminal hummed quietly, its screen filled with trigger configuration diagrams that would have been incomprehensible months ago.
Now Memory Architecture stored them with perfect fidelity while Trigger Adaptation whispered interpretations I couldn't consciously access.
Raygust: Defensive mode generates shield proportional to trion input. Thrust mode converts shield energy to offensive capability. Transition window: 0.3 seconds of vulnerability.
I scrolled through specifications, absorbing data faster than normal reading speed allowed. The anime had shown triggers in action; these documents revealed the engineering beneath — modular components, power routing matrices, safety limiters that prevented configurations outside approved parameters.
Trigger Adaptation stirred with each page, perceiving components as elements that could be rearranged rather than fixed systems locked into standard function.
The ability was waking up. Not fully — not yet — but enough to suggest possibilities the documentation didn't acknowledge.
"Interesting choice of reading material."
The voice came from behind me. I turned to find Tamakoma's equipment engineer — Hayashi, according to the badge — studying my screen with professional curiosity.
"I'm trying to understand my trigger better," I said. "Raygust has capabilities I'm not utilizing fully."
"Most agents don't bother with specifications." Hayashi moved closer, scanning the diagrams I'd been reviewing. "They learn by doing. Trial and error in the field."
"I learn better from understanding principles first." True, and insufficient explanation for someone absorbing classified engineering documents at abnormal speed.
"These particular specifications—" Hayashi's tone shifted, carrying new weight, "—include defensive-offensive threshold theory. That's not public documentation."
The observation landed like cold water. Memory Architecture had supplied the query without flagging its classification level. I'd asked about threshold theory as if it were common knowledge, revealing access to information a C-Rank trainee shouldn't possess.
"I read it somewhere," I said. "Maybe wrong source."
"Maybe." Hayashi's expression had closed off, professional friendliness replaced by cautious assessment. "Threshold theory is development-level material. Engineers discuss it; agents don't study it."
"I'm interested in how things work." The deflection felt desperate even as I delivered it.
"Clearly." He made a note on his tablet — another entry in the informal record of Mikumo Osamu's unusual knowledge. "Let me know if you have other questions. I'll try to answer the ones that aren't above your clearance."
He walked away without waiting for response, leaving me alone with the terminal and the weight of another mistake.
The engineering section emptied as evening shifted toward night. I remained at my terminal, no longer reading specifications but sketching.
Trigger Adaptation flowed through my hands, bypassing conscious thought to produce diagrams I didn't fully understand. Raygust configurations that shouldn't work according to standard parameters — defensive mode channeled through offensive attack vectors, shield energy converted to blade reinforcement without transition vulnerability.
The sketches made no sense to my analytical mind. But something deeper insisted they were possible.
I remembered the rooftop training sessions where Combat Evolution had optimized movements I couldn't consciously track. The same principle applied here: ability operating below conscious awareness, producing results that emerged fully formed rather than developing through deliberate effort.
Trigger Adaptation wanted to modify equipment. My hands sketched modifications before I could evaluate them.
The implications were significant. Standard triggers operated within manufacturer parameters, their capabilities fixed by engineering decisions made before deployment. If Trigger Adaptation could perceive modifications that exceeded those parameters...
I folded the sketches into my notebook, hiding evidence of understanding I couldn't explain.
Not ready to test. The invasion was five days away; experimentation now risked equipment damage that would compromise combat capability when it mattered most.
But soon. After the invasion — assuming survival — I'd have time to explore what Trigger Adaptation was showing me.
The walk back to Tamakoma's main building took me through corridors that had grown familiar over weeks of navigation. My hand ached from hours of sketching; I flexed fingers that had cramped without my noticing.
Six hours. I'd been studying and sketching for six hours without awareness of time passing.
Memory Architecture had done this before — absorbed information so efficiently that hours vanished into processing. Trigger Adaptation apparently worked the same way, capturing my attention so completely that physical needs went unnoticed until ability exhaustion forced awareness back to the body.
Dangerous. If abilities could override basic self-monitoring, pushing them too hard might cause damage before warning signs registered.
I added the observation to the growing list of concerns that had no good solutions.
The common room was empty when I arrived — late enough that even Yūma had retreated to the bunks. I settled onto the couch with my notebook, reviewing sketches that looked like someone else had drawn them.
Raygust modifications. Defensive mode transitions. Shield energy routing that violated standard engineering assumptions.
Trigger Adaptation insisted they would work. I couldn't explain why, couldn't trace the logic that led from standard specifications to experimental configurations.
But I believed it. The ability had never lied to me about what was possible, only about what was practical.
I closed the notebook and let my head fall back against the couch cushions. Exhaustion pressed down — physical, mental, the accumulated weight of preparations that felt inadequate no matter how comprehensive they became.
Five days. The invasion was coming whether I was ready or not.
The notebook's sketches waited in my pocket, theoretical configurations that wouldn't stay theoretical much longer. When combat pushed capabilities to breaking points, experiments became necessities.
I'd built the weapon before needing it. Standard transmigrator strategy: prepare for problems you knew were coming, even when preparation created questions you couldn't answer.
The clock on the wall showed 11:47 PM. Four days and twelve hours, if Memory Architecture's invasion timeline was accurate.
I pushed myself upright and headed for the bunk room, forcing legs to carry me despite their complaints. Sleep was necessary; tomorrow would bring more training, more preparation, more countdown toward the moment when everything changed.
The sketches stayed in my pocket, waiting.
Sometimes you built weapons before you needed them. Sometimes that was the only advantage preparation could provide.
The bunk room was dark except for the faint glow of Yūma's Black Trigger ring. I navigated by Spatial Cognition's passive awareness, finding my bed without disturbing anyone.
Chika slept in the adjacent room, dreaming whatever dreams she had about brothers and guilt and the weight of impossible power. Yūma's small form was still in his bed, though whether Neighbors actually needed sleep remained unclear from canonical sources.
My squadmates. My responsibility. The people I'd fight beside when the invasion came.
I closed my eyes and let exhaustion pull me under, knowing that tomorrow would bring more preparation, more countdown, more weight.
Four days. The number sat in my awareness like a stone, immovable and cold.
The trigger sketches pressed against my chest through the notebook's fabric. Theoretical configurations that would become practical tests when circumstances demanded.
Sleep came eventually, carrying me through hours of rest that never felt sufficient. When morning arrived, I'd continue preparing.
Until then, the darkness held its silence, and the countdown continued whether I watched it or not.
