Natsuki had used a spatial barrier to cover the entire side of Ninja Star, blotting out the sky and sun.
This spatial barrier was pitch-black, sealing off the outside into another world.
On the Ninja World's side, the sky suddenly went dark.
All light vanished completely, and the temperature quickly began to drop.
Lights were lit in many places.

Minato and the others could only look toward Natsuki.

Stars came in different sizes, but the one beside Ninja Star was more than a hundred times larger than Ninja Star itself.
Then there were the high temperatures, rays, and radiation—permanent buffs for a star.
If Yōshiki moved that celestial body at all—
The magnetic field changes caused merely by approaching any planet could wipe out all life on it.
And high temperatures, rays, and radiation could kill ordinary people in an instant.
Ordinary methods could not destroy a star at all.
Even for Star God-level experts, destroying a star was a losing proposition.
A dying star would trigger a supernova explosion.
The sudden electromagnetic radiation released during the process could often illuminate the entire galaxy it occupied.
The energy radiated by a supernova during that period could rival the total energy the sun radiated throughout its lifetime.
In this vast stretch of the universe, all life on any celestial body exposed
