Its The Kid

"That voice..." Gradier Xanatus muttered as he stared at Red Shadow.

"It's the kid," Both of them stated at the same time.

They both had looks of confusion and disbelief mixed on their faces.

They were not hearing the voice from their ears, instead they were hearing it within their minds.

-"Gradier Xanatus, Red Shadow can you hear me?"

'Gustav, is that you?' Red Shadow asked internally.

-'Yeah,'

'How are you doing this kid?' Gradier Xanatus questioned within his mind as well.

It turned out a kind of mind link had been created where Red Shadow and Gradier Xanatus could hear each other and converse with Gustav as well.

-'I'm currently at the borders of Luchan City, battling the hoardes of infected,' 

'You came here?' Red Shadow responded with a tone of surprise since he recalled Gustav stating he was busy with something.
