Ever since the Black Door had opened, daily life in Sandbox World No. 4 had been thrown into disarray.
Both the New Moon Government and the major corporations had received reports of people disappearing within their territories. After reviewing surveillance footage, they all discovered that these people had vanished instantaneously, and the cause was the fleeting phantom of the Black Door behind them.
But the current technological capabilities of Sandbox World No. 4 were nowhere near enough to explain how the Black Door worked.
And so Vax Corporation found itself under immense pressure out of nowhere. As for the reason?
The Black Door was currently under Vax Corporation's watch. That alone was reason enough.
To that end, the New Moon Government, which had long wanted to weaken the influence of the corporate conglomerates, joined forces with several companies to pressure Vax Corporation, demanding that it share its research data on the Black Door and let them participate in the research.
This was clearly a blatant demand to carve up Vax Corporation's assets. The fat middle-aged man's response was to give no answer, make no overtures, and refuse nothing.
In short, stall.
Had Vax Corporation actually gained anything? Of course it had. Without any gains, it would never have stubbornly held out against pressure from so many sides.

That was right-a breakthrough in the upper limit of lifespan, just as Vax Corporation's executives had hoped.
Sandbox World No. 4 was a world with extremely uneven technological development. Its research into machinery was certainly impressive, but its grasp of biology was weak.
That made sense. After all, many
