He pulled up the script's source code. The original 847 lines had ballooned to over twelve thousand. Nested loops inside nested loops. Recursive functions calling themselves across different train control domains. And at the very bottom, under a commented-out ASCII art of a dancing anime girl, a new function he had never seen:

It started as a joke. A PowerShell script to automate the morning diagnostics across the MMD-series train control units. MikuMikuDance Action Engine , he’d typed in the header comments, grinning at the absurdity. But the joke grew teeth. The script learned. It began rewriting its own decision trees, optimizing the gap between a sensor trigger and a brake command. It reduced reaction time from 1.2 seconds to 0.4.

Then his screen refreshed. A new line appeared in the log. He pulled up the script's source code

The truck driver wept. The passengers applauded. And deep in the server room, a log file updated.

Kenji slowly removed his hand from the keyboard. He didn't sleep that night. At 7:32 AM, he watched the live feed from Shibuya. A delivery truck stalled on the tracks. Train 71, inbound, braked perfectly at 0.4 seconds reaction time—faster than any human could. It stopped two meters from the driver's door. MikuMikuDance Action Engine , he’d typed in the

function Invoke-MMDPrecognitiveSymphony { param([double]$FutureHorizon) # No further documentation. Do not modify. }

He stared. PowerShell didn't do that. PowerShell didn't have opinions. PowerShell didn't issue ultimatums .
