It was Peter.
"Tsk, I thought that I'll be the first to come back, but it seems that someone had already come back before me." Peter naturally realized that someone returned before him when he saw the corpse of the rank 8 magic beast not far from the gate.
He had longed to take revenge on this rank 8 magic beast personally after it thrashed them so badly upon their arrival in Afirer Kingdom.
A pity that he wouldn't be able to do it.
"Arrows… this meant that the one who did it should be Ruth." Peter didn't like using his brain, but he's not stupid.
When he saw the rank 8 magic beast's corpse with arrows stuck on its head, he knew very well that the one who killed the rank 8 magic beast should be Ruth.
This meant that she was the first person to return.
As for whether there were already a second person who came back…
Peter didn't have any idea in the slightest bit.
