——A few moments prior
Outer Bunker Area.
"What's going on…? Can you hear anything?"
"No, it's soundproof."
Aoife answered while massaging her right cheek. It was still hurting, and just thinking about Kiera who had slapped her just a few moments prior, she glared at her.
"What?"
"….You know what you did."
"What did I do...?"
"Hah."
Aoife took a deep and heavy breath to calm herself down. She was really having a hard time. The more she looked at Kiera, the more her hand twitched.
'I'm better than this.'
That's right, she couldn't stoop down to her level.
Rumble! Rumble!
"Uh…?!"
A distant rumbling disrupted Aoife's thoughts. She could feel it through the vibration of the floor. Turning her head, her expression changed.
It wasn't just hers.
