Kamille glanced at the native without any hint of pressure, but this calmness was precisely the reason the native remained cautious. Zenos could not read or see anything about him.
"This is a gate." Kamille honestly told the native the reason, this was not a secret. This world also had gates, which could help the natives understand the situation.
After glancing once at the unconscious Esper, Kamille did not pay attention to him and instead continued to explain. They were there to gather explanations and not actually to make an enemy of the natives.
That at least was their first intention.
Ignoring the confusion that appeared on the native's face, Kamille spoke unhurriedly. "This world is connected to our world through a special gate. We're here to investigate."
Kamille did not seem bothered whether the native believed him or not. He also spoke in such a concise manner, not really explaining everything.
