"It hasn't even been ten minutes since we arrived, and Erza has already noticed us!" exclaimed Idan excitedly, addressing Arabel through a mental link.
"System! How is this possible? Do you have any suggestions?"— in this serious situation, Idan did not waste time thinking and immediately turned to a System that had deeper knowledge and could discover what was inaccessible to Idan.
[Host, this System has not detected any tracking devices, spells, or other similar devices on the Hosts.]
This response from the System did not calm Arabel's or Idan's worries.
"But somehow she noticed us!" insisted Arabel.
[Although this System has not detected anything suspicious, it has some assumptions. Perhaps the Hosts have been spotted by another creature that has a blood connection to the one with whom the Host has entered into a symbiotic relationship.]
"What?" exclaimed Arabel.
