Hearing Kranos's question, Rose smiled lightly. She understood Kranos deeply; even though it seemed he was asking out of despair, he actually had a means of escape and just wanted to take advantage of that to gain information about them before departing.
She was truly impressed with Kranos at the thought. Since he possessed the space element, a rare element, an idea quickly formed in her mind: "You possess a rare element and are extremely smart. Why don't you join our organization? If you do so, your life will no longer be in danger."
Kranos glanced at her coldly. Her voice felt faintly familiar, but he couldn't recall where he had heard it. He understood what Rose was implying, and he couldn't help but frown deeply. Basically, it seemed like she was inviting him to their organization, but it was more like a threat.
