Karoline handed him the crystal, and kept dancing around as if she was really waiting for magic to happen. He rolled his eyes, looked at her and didn't say anything when he noticed how excited and happy she was.

He then turned to focus over the crystal he got in his hand. When he saw the little white dots there, he couldn't help but recall the first time he tested his spirit power after coming back from the future.
