Mobile Operator

Two mysterious guys were standing next to a giant machine. They had been hiding in this city for a while.

"The communication has been cut off," said one of them while checking his device. "Should we begin?"

"…" The other guy maintained his silence while looking at the radar. "How far is the range of this machine again?"

"About ten kilometers. It should be enough to reach the center of the city. Even though it is weak, there is still a chance that the Tier 3 beast will also get disturbed by the sound." 

The man frowned. "That lass from the Renvolt family is moving. It seems that she is trying to stop the jamming device." 

"What? This soon? Does she know where they are?"

"I'm not sure. If I'm not wrong, they have a new operator, right? Who is it?"

"I don't know. I have been trying to find the information, but other than the fact that there is a new operator, I can't get anything else."

"Is it erased?" The guy frowned.
