The kaiju swung and Riku ducked.
Not a tactical decision — pure instinct, the kind that bypasses thought entirely and goes straight from stimulus to motion. The fist, if you could call it that, a dense mass of calcified hide and knuckle-bone the size of a delivery truck, passed over his head close enough that the displacement of air hit him like a wall and sent him sliding three meters across the cracked asphalt.
He caught himself. Straightened. Looked up.
The kaiju was already pulling back for another swing.
*Okay,* Riku thought, with the particular calm of someone whose brain had decided panic was temporarily unavailable. *Okay. Think.*
The system prompt still hovered at the edge of his vision, patient and unbothered.
**MISSION: SURVIVE**
**Objective: Remain alive until Defense Force arrival.**
**Time remaining: 05:11**
Five minutes. He could survive five minutes.
The kaiju's second swing came faster than the first. Riku broke left, felt the shockwave as the fist impacted the building behind him, and kept moving. Debris rained down — chunks of concrete and glass that bounced off his armor like gravel. He registered the impacts but not the pain. The Hollow Frame absorbed it, distributed it, turned what should have been injury into nothing more than information.
*So that's what it does.*
He filed that away and kept running, putting distance between himself and the kaiju's immediate reach. The creature turned to follow him, slow in its pivoting but inevitable, the way something that large didn't need to be fast because nothing in its experience had ever successfully run from it.
Riku stopped at the end of the block and faced it.
The kaiju was forty-three meters. He was one-point-seven-eight. The math was, objectively, terrible. But the system had given him a mission to survive, not a mission to win, and right now surviving meant keeping this thing's attention on him and away from whatever stragglers were still moving through the evacuation corridors to the north.
He needed to be annoying. He could do that.
"Hey." He said it out loud, which was arguably pointless since kaiju didn't process language, but it helped him think. "Over here."
The kaiju's four eyes tracked him. Its jaw split and a sound came out — not a roar exactly, more like pressure, like standing too close to a speaker playing a frequency humans weren't designed to hear. Riku's armor vibrated faintly in response.
Then the system chimed.
*"KAI resonance detected. Passive scan complete."*
*"Target analysis available."*
New text appeared, overlaid on the kaiju like a diagnostic readout.
**KAIJU — UNCLASSIFIED / ESTIMATED RANK: MEDIUM**
Structural weakness: Lateral joint, left rear leg.
Recommended engagement: Evasion and disruption. Do not engage core mass directly.
*"You are not strong enough for that yet, No. 0."*
That last line didn't feel like information. It felt like the system was editorializing.
"I wasn't planning to," Riku muttered.
He moved before the kaiju's next strike landed, breaking right this time, cutting across the street in a diagonal sprint that brought him closer rather than farther. The kaiju tracked him but its reaction time worked against it — by the time it recalibrated, Riku was inside its reach, too close for the big swings, moving along its left flank.
He hit the lateral joint of its rear left leg with a running strike, palm-heel, everything the Hollow Frame's reinforced density could put behind it.
The kaiju stumbled.
Not much. Not dramatically. But one leg buckled slightly and the creature's balance shifted and for two full seconds it was occupied with not falling over rather than occupied with killing him. Riku was already clear, back across the street, watching.
**MISSION: SURVIVE**
**Time remaining: 03:44**
Three minutes forty. He could do this.
---
He kept moving.
That was the strategy, such as it was — keep moving, keep the kaiju chasing, hit the weak point whenever an opening appeared, never stop long enough to become a stationary target. It wasn't elegant. It wasn't the kind of combat the Defense Force trained for, all coordinated squad movements and specialized anti-kaiju weaponry. It was just a man in borrowed armor making himself an irritant to something that could level a building by leaning on it.
But it was working.
The kaiju had stopped progressing northeast. It was fully turned on Riku now, all four eyes locked on, jaw cycling open and closed with that subsonic pressure-sound. It had tried three more major strikes and connected with none of them. The street between them was cratered and scattered with debris, every impact a testament to how close it had been.
Riku's arms were getting tired.
That surprised him — he'd assumed the armor handled that too. But the Hollow Frame reinforced him, it didn't replace him, and the body underneath was still twenty-two years old and running on convenience store coffee and six hours of sleep. His legs were fine. His cardio was fine. His arms, which had been absorbing the feedback from every strike he'd thrown at the kaiju's weak point, were singing.
He noted it. Adjusted. Stopped throwing strikes and focused purely on movement.
**MISSION: SURVIVE**
**Time remaining: 01:58**
Almost there.
The kaiju changed tactics.
Instead of swinging, it simply stepped forward and brought its full weight down toward him, a stomp that turned a two-meter section of road into a crater. Riku was already moving but the shockwave caught him mid-stride and sent him airborne — not gracefully, not intentionally, just suddenly off the ground and then very suddenly back on it, rolling across asphalt that scraped against his armor with a sound like grinding metal.
He came to a stop against an overturned vending machine. Lay there for a moment, staring up at the ash-grey sky.
The kaiju loomed over him, jaw open.
*Okay,* he thought again. *Less okay than before.*
The system, apparently sensing the shift in circumstances, chimed with what might have been urgency if it were capable of anything as human as that.
*"Mission parameter update."*
*"Survival is still the objective."*
*"Recommend immediate evasive action, No. 0."*
"Working on it," he said, and rolled left as the kaiju's jaw came down and snapped shut on the space his head had been occupying a half-second earlier.
He was back on his feet before the creature could recalibrate. Armor still intact — the fall had done nothing to it. His own body was bruised underneath, he could tell that much, but bruised was fine. Bruised was survivable.
**MISSION: SURVIVE**
**Time remaining: 00:41**
Forty-one seconds.
The kaiju raised its foot again.
Riku ran — not away, sideways, along the building line, keeping close to the facades so the creature couldn't get a clean stomp angle without risking bringing the structures down on itself. It followed, slower now, the damage to its left rear joint accumulating into a visible hitch in its movement.
Thirty seconds.
He heard it before he saw it — the distinctive engine drone of Defense Force dropships, low and fast, coming in from the southwest. A sound he'd grown up hearing from a distance, always someone else's fight.
Twenty seconds.
The kaiju heard it too. Its four eyes broke from Riku and swept upward. Something in its behavior shifted — not fear, kaiju didn't process fear the way anything else did, but a recalibration, a recognition that the variables had changed.
Ten seconds.
The dropships crested the roofline, three of them in combat formation, and the radio frequencies that Riku's armor was apparently capable of receiving without his permission crackled to life with Defense Force tactical chatter.
*"Target confirmed, Grid 7-B. All units prepare for engagement. And —"* a pause, *"— what is that on the ground?"*
The mission prompt updated one final time.
**MISSION: SURVIVE**
**STATUS: COMPLETE**
**Reward: 500 XP | STR +2 | AGI +2**
**New mission available.**
Riku looked up at the dropships. Looked down at his armored hands. Looked at the kaiju, which was now splitting its attention between him and the aircraft above.
*Right.*
He was still transformed. Standing in the middle of a combat zone in full kaiju-derived armor while three Defense Force dropships hovered overhead with their weapons systems absolutely pointed in his direction.
The system offered, with what Riku was increasingly convinced was deliberate timing:
*"Recommendation: Disengage Hollow Frame."*
He released the transformation. The armor receded the same way it had come — quietly, completely, like a tide going out. In two seconds he was standing in the street in his debris cleanup vest and hard hat, scanner still clipped to his hip, looking up at the dropships with the expression of a man who had absolutely not just been doing something deeply unusual.
The tactical channel crackled again.
*"Ground contact — identify yourself."*
Riku reached up and clicked his radio on.
"Shiro Riku," he said. "Disaster Prevention Corp, cleanup division. I got separated from my team during evacuation." A beat. "The kaiju has a weak point in its left rear lateral joint. Thought you should know."
Silence on the channel. Then, dryly:
*"...Copy that, civilian. Fall back to the northern rally point immediately."*
"Yes sir." He clipped the radio off and turned north.
Behind him, the Defense Force opened up on the kaiju. The sounds of actual combat — weapons designed for this, people trained for this — filled the air. Riku walked away from it with his hands in his pockets and his heart rate slowly returning to something that wouldn't concern a doctor.
The system chimed softly in his ear.
*"New mission unlocked: Enlist."*
*"Objective: Pass the Defense Force entrance examination."*
*"Third attempt recommended."*
Riku stopped walking. Stared at nothing for a moment.
"You're serious," he said quietly.
The system did not respond. It never responded to things that weren't questions it felt like answering.
He started walking again.
Third attempt. After two failures, after eight months of telling himself he was done with that particular dream, after building an entire architecture of acceptance around the fact that he simply wasn't cut out for it —
The system thought he should try again.
And the thing was, walking away from a forty-three meter kaiju that he'd kept occupied for over five minutes using nothing but the armor on his back and stubbornness —
He was starting to think the system might have a point.
