Chapter 7 : Integration Protocol
Konami's blade caught me across the chest before I registered she'd moved.
My trion body flickered, destabilized, and I hit the mat hard enough to drive the breath from my lungs. Four seconds. That was the entirety of my sparring debut at Tamakoma Branch — four seconds of futile defense against someone who'd clearly held back the entire time.
"You're slow." Konami's voice carried no malice, just observation. She deactivated her trigger and offered me a hand up. "Also predictable. You telegraph your dodges about half a second before you make them."
I took the hand. My arms were still tingling from the impact. "Noted."
"Don't look so down." She grinned, the kind of fierce joy that came from someone who genuinely loved combat. "Most rookies don't last two seconds. You've got decent instincts — just no power to back them up."
Combat Evolution stirred, filing the exchange. Konami's attack speed. Her footwork patterns. The slight drop in her shoulder before a thrust. Data I couldn't use yet, but data that would matter eventually.
"Konami, stop traumatizing the new recruit." Karasuma emerged from the observation room, expression mild. "He's been here less than an hour."
"Sparring is bonding!"
"Sparring is sparring. Bonding is what happens after they can walk again." Karasuma approached, studying me with the clinical attention of someone who'd trained dozens of agents. "Your form isn't bad, Mikumo. Your trion just can't support it."
"I know." The words came out more bitter than I intended. "Lowest combat score in Border's records."
"That's what the numbers say." He tilted his head slightly. "But numbers don't explain why you lasted four seconds against Konami. She's A-Rank. Most B-Rank agents would've gone down in two."
"Spatial awareness exercises," I said. "I practice perceiving my surroundings without relying on direct sight. Helps me anticipate attacks slightly earlier."
True. Incomplete, but true.
Karasuma's eyes narrowed thoughtfully. "Interesting approach. We should explore that during proper training sessions. But for now—" he glanced at the clock on the training room wall, "—you should meet the rest of the branch. Yōtarō's been asking about you since you arrived."
The name conjured an image: small kid, hyperactive, rode around on a capybara that was secretly Earth's Crown Trigger. One of the details I'd cataloged from the anime without fully understanding its significance.
"The kid with the... animal?"
"Raijinmaru." Karasuma's expression softened slightly. "Don't underestimate either of them."
I found Yōtarō in the common area, sprawled on the floor with a manga volume, Raijinmaru serving as a furry pillow. The capybara's eyes tracked me as I entered — intelligent, assessing, nothing like the dopey expression suggested.
Crown Trigger. The most powerful weapon under Earth's Mother Trigger's control, disguised as a pet. I forced myself not to stare.
"You're the weak one."
Yōtarō's voice held no judgment, just a child's blunt honesty. He sat up, manga forgotten, studying me with the same directness I'd seen in Yūma.
"That's me."
"Konami beat you in four seconds. I counted."
"I'm aware." I settled onto the couch across from him, keeping my body language relaxed. Kids noticed tension. "Did you watch the whole spar?"
"Most of it. Jin-san said you'd be interesting." Yōtarō's head tilted. "Why are you at Border if you're so weak?"
The question hit differently than I expected. Not mocking — genuine curiosity. A child's logic that cut straight to the point adults would dance around.
"Because I can help in ways that don't need strength."
The honest answer surprised me. I'd prepared deflections, careful framings, strategies to manage expectations. But facing Yōtarō's uncomplicated curiosity, the truth came out first.
"Like what?"
"Strategy. Positioning. Knowing where to be so stronger people can do their jobs better." I shrugged. "Someone has to think about the whole picture while the Konamis of the world are hitting things."
Yōtarō considered this. Raijinmaru made a soft sound — not quite a bark, not quite a rumble — and the kid nodded as if receiving counsel.
"Raijinmaru says you're weird."
"He's probably right."
"He says your trion feels funny. Like it's not from here."
My blood chilled. The capybara's eyes met mine, and for an instant I saw something ancient and knowing behind that animal facade. Crown Trigger. Connected to Earth's dimensional foundation. Of course it would sense that my soul came from somewhere else.
"Equipment calibration issue," I said, keeping my voice steady. "Border's medical team noted something similar. Probably just a natural variation."
Yōtarō shrugged, already losing interest. "Can you reach the snacks?"
The shelf in question was mounted high on the wall — child-proof positioning that hadn't accounted for Yōtarō's determination. I stood, grabbed the container of rice crackers, and handed it down.
"Thanks." He immediately offered one to Raijinmaru, who accepted with solemn dignity. "You're not that bad for a weak person."
"High praise."
He went back to his manga, and I retreated before the capybara could sense anything else unusual about me.
Usami found me in the communications room an hour later, reviewing Tamakoma's mission logs with Memory Architecture's hungry attention.
"Captain Mikumo!" She appeared at my elbow without warning, tablet in hand. "You're settling in okay?"
"Just studying branch history. Trying to understand how Tamakoma operates differently from HQ."
"Smart approach!" Her enthusiasm remained undimmed despite my obvious absorption in the files. "Most new members just jump into training without learning the context. Rindō-san appreciates people who do their research."
I filed that information alongside everything else. Political capital through demonstrated diligence. Useful.
"Oh, and reminder — your medical intake is scheduled for tomorrow morning. Nine o'clock, medical bay level two. Standard procedure for branch transfers, but they'll want complete scans since your file is technically still C-Rank."
"Understood."
She paused, studying me with more perception than her cheerful manner suggested. "You seem tense. First day nerves?"
"Something like that." Not a lie — the medical intake was tomorrow, and I had no idea how sensitive Border's equipment would be to my transmigrator signature. The rooftop watcher from weeks ago still haunted my peripheral thoughts, and now Raijinmaru had apparently detected something wrong with my trion.
Evidence was accumulating. I needed to stay ahead of it.
"Don't worry too much." Usami patted my shoulder with genuine warmth. "Tamakoma takes care of its own. Whatever the tests show, you're one of us now."
The kindness landed harder than it should have. After weeks of dismissive instructors and skeptical peers at main branch, someone treating me as a person rather than a statistic felt almost foreign. I'd gotten so used to performing adequacy that I'd forgotten what acceptance felt like.
"Thanks, Usami-san."
"Shiori is fine." She smiled and headed back toward her station. "Get some rest tonight. The machines can tell when you're sleep-deprived."
The bunk room assigned to male members was small but functional — two beds, storage lockers, a window overlooking Tamakoma's garden. Yūma had claimed the bed by the window without discussion, though he wasn't there when I arrived.
I lay on the remaining mattress and stared at the ceiling, running scenarios through Memory Architecture's perfect recall.
Medical intake. Trion signature analysis. The machines would see my out-of-phase frequency — the dimensional displacement left by a soul that didn't originate in this universe. The question was whether they'd recognize it as anomalous or dismiss it as equipment noise.
Deflection strategy: attribute any irregularities to natural variation or equipment calibration. Most technicians defaulted to mundane explanations when faced with unprecedented readings. The alternative — admitting their machines detected something impossible — required institutional courage most people lacked.
But the record would exist. Somewhere in Border's files, a note about Mikumo Osamu's unusual trion signature. Waiting for someone with the right curiosity to find it.
I couldn't prevent that. I could only manage the response.
The ceiling offered no answers. Outside, I heard Yōtarō's laughter and Konami's booming voice arguing about training schedules. Normal sounds. Branch sounds.
Tomorrow the machines would look at my soul. Tonight I practiced breathing evenly, convincing my body that the fear was manageable.
Thirty-five days until the invasion. Medical intake at nine.
I closed my eyes and let Memory Architecture run tomorrow's scenarios while my body pretended to rest.
