The darkness obscured their figure, but Arthur saw them standing atop the mast of a leaving ship. The familiarity grew stronger, and Arthur was sure that it was someone he knew from Earth. Finally, however, they disappeared without a trace, leaving Arthur dazed.
"Who was that?" Arthur wondered, but he couldn't summon the memory. Finally, however, he was sure that it was someone he knew, but he couldn't see their face or figure.
As his detection covered the land, Arthur found no trace of them, only the leaving ships. He grew disheartened again for the loss of a chance to meet someone he knew, but he was somehow relieved and terrified.
At least Arthur wasn't the only person in Alka, but it meant that someone he knew was in this dangerous world. After thinking that he lost them again, Arthur detected an abnormal presence with his mana.
