Aren, Kurumi, and Logan could hear everything because Aren had left a tiny hole in the wall to observe. After all, he could manipulate the shape of this wall according to his will.
So when they heard the vile thoughts of that bastard, Kurumi said, "Aren, let's save her before she dies. Her barriers will also make our journey easier."
"Yeah," Logan nodded, "if we save her, then she is sure to repay. Our defense will increase a lot with my path and her path powers."
"Alright," Aren nodded, "but we'll have to do it quickly."
Aren then made a slightly larger hole and sent his chain whip gear [Lech] into the hole before controlling it to move towards the woman. Aren had also attached his comm crystal to the chain after activating it.
The chain arrived at the woman and bound her.
"Don't attack it. I sent this chain to save you!"
The woman heard the voice from the comm crystal and relaxed. She would definitely die if she stayed here, so there was no other choice but to go with this.
