"Wait?!" Astrid gasped, "Those were his scales? Not real clothes?" She looked at Mira and Isdis in shock.
"Yeah, they act like normal clothes though, he just can't take them off." Mira replied. While Arad's scales are morphed into clothes, they must keep a link to him, which takes form in a spot where they are stuck to his body. The advantage to wearing his own scales like this is that they are far more durable than any armor, and would allow him to fight freely without worrying about getting his clothes burned by a fire breath or something like that.
"What worries me…" Tina looked at Astrid with a worried face. "Master Arad's scales are extremely tough and durable. I find it hard to imagine someone leaving him this exhausted."
"Tina is right. Arad should've been able to recover quickly…" Mira glared at Astrid, "Who really is that Kayden? We've seen him before, but is he really that strong?"
