In the pitch-black universe, a crimson planet
was orbiting the sun along a trajectory opposite to that of the other planets.
Swish, swish.
With a flash of light, two figures appeared out of thin air in the planet's low orbit.
"Look, Venus."
Yu pointed at the crimson planet beneath their "feet." Wrapped in sulfuric acid clouds twenty to thirty kilometers thick, the clouds reflected as much as 70% of the sunlight—far exceeding that blue-and-white planet's 30%. As a result, this planet was the brightest natural object in the night sky, second only to the moon.
Now that Yu and his sister were observing it from so close, it gave off a scorching pale yellow glow as a whole, covered in orange-white streaks that lit up continuously like lava.
"That's the flash produced by Venus's intense lightning activity."
Yu explained it to his sister. After all, this was his "territory," so he was far more familiar with it than his sister, who was here for the first time.
"It looks like a planet made of lava."
His sister, whom Yu had dragged out "traveling," studied the planet below and gave that description.
"Yes, and no."
That was how Yu responded to his sister's words.
On the surface, Venus did indeed look like a lava planet, due to its atmosphere reflecting sunlight and the intense lightning activity. His sister did not possess any eye-type Kekkei Genkai, so she could not see through the sulfuric acid clouds thirty kilometers thick.
But Venus truly was a planet with lava flowing everywhere.
"What we're seeing now is only Venus's atmosphere. The ground is below—"
Holding his sister's hand, Yu flashed away. The two of them passed directly through dozens of kilometers of sulfuric acid clouds and appeared above Venus's "surface."
"Hmm?"
His sister turned her
