Eren didn't answer the question right away. He used Identification to check the information on the man before him.

"Hmm?"
A secret appeared before Eren, but it didn't give any useful information to him at all. This was the first time that even the name of the person was filled with question marks in the identification screen.
Looking at the screen, Eren's bad feeling was further solidified. The person in front of him was not someone that he could handle alone.
Even if it was the Ice Maiden Palace, he could at least find a way to leave. But this man was clearly different. He even knew the Sword Emperor, and managed to guess a link in between them.
"I will ask you again. What is your name? And what is your relationship with that man? Why do you carry his sword?"
