BANG!!!
Smoke and dust rose from beneath Killer's shoes, veiling her figure like a thin gauze. Standing at the center, Killer lowered her head slightly and gently brushed the dust off herself.
"Almost lost HP from that fall."
After taking a moment to steady herself, Killer turned her attention to her surroundings-
It looked... a little hard to describe, but if she had to...
A bit like the rabbit hole in Alice in Wonderland?
An endless expanse of pure green grass covered every corner like an enormous plush blanket, as though it meant to wrap up the entire earth.
When she looked up, the ceiling, resembling a blue-and-white sky, was like a crystal-clear sapphire, radiating a mesmerizing glow. The fresh, pleasant air carried the scent of grass.
Killer looked around again and saw that the walls were covered in alternating green and blue wallpaper. The unusual combination of colors lent the place a peaceful yet mysterious feel.
Every detail told her that this was not the Underground world she had originally been in, but somewhere entirely different. In this new environment, everything was so beautiful and peaceful that even time seemed to have stopped.
But on second thought, Killer took it in stride. She was currently in a disorderly space practically synonymous with chaos. In a place where both time and space were scrambled, there was no point dwelling on those earlier questions.
Following the passage, Killer soon found the exit to this strange room-
A wooden door utterly at odds with the beautiful scenery.
"All right. In that case..."
Killer rubbed her hands together, her foot gouging a crack in the ground-
WHOOSH!
CRACK-
The pressure of the air followed Killer's kick, instantly splitting the wooden door in two.
"Squeak squeak squeak squeak squeak squeak squeak squeak squeak squeak!!"
