When Ayame, Bianca, and Winston noticed the green-colored mist, they immediately retreated away from it as they perceived danger from it.
"That mist is poisonous! Likely the ability of an Awakener with poison superpower."
Winston informed Ayame and Bianca after his Eye of Insight saw through the green-colored mist's properties.
The three of them weren't ignorant and they knew that whoever was inside the skyscraper was hostile to them.
Because of that, Ayame no longer hesitated as she used her space manipulation on the skyscraper.
But before she could use gravity manipulation to lift the skyscraper and destroy it, Ayame was shocked to discover that her control over the skyscraper disappeared!
"My superpower seemed to be negated when I wanted to control the skyscraper!"
Hearing Ayame's discovery, Winston wanted to test it so he aimed his two pistols towards the skyscraper.
