Arad himself wasn't fully awake, as this entire thing still felt like a dream to him. But being lucid, his mind was still fully aware and conscious. Standing still, feeling the waves of magic those monsters below released, he thought about his next move carefully. This was Pin's body after all, and she wouldn't like him using it to start a fight.
Checking how much power he could access, he was pleasantly surprised to find out that he could access almost 100% of his prior power. That was the catch: right now, his true body was far stronger than his adult form. But that was just this avatar, not his true power.
Pin's cloak turned darker and covered her whole body, and Arad soon pulled the hood over his head, hiding his face. The moment he did that, Pin's entire presence faded inside him, and he was the dominant soul.
