As Melba stepped inside the room talking in a relaxed tone, a loud metal noise suddenly rang somewhere clattering.
When the Shesters noticed the sound and were surprised, they heard some loud clock gear spinning in turn.
"... what is this sound!?
Even though Shester raised his voice unexpectedly, the metal sounds overlapped even more varied and played complex sounds like an orchestra.
Then, suddenly, a loud ground sounded and a crack ran in a straight line in the middle of the floor.
And with the roar, the floor slid sideways, and the crack gradually became a big hole.
"Run to the exit!
Shester screams, everyone rushes to the exit.
But in the meantime, there came out those who fled late and were stuck.
It is Comet.
Comet stood up on the spot and solidified, sliding against the wall with the floor.
"... Wow... Ugh..."
Comette didn't know what to do, and even as she hurried and sighed her little groans, her body was finally driven to the wall, and her scaffolding gradually dwindled.
"Comet!"
Elba screamed as she peered into Comet's face from the exit she had escaped.
But Comette could not afford to answer her sister, and she was afraid all the time as she drew her face to fear.
