"So... Ichigo is human, and Hollow, and Shinigami, and Quincies?" Sounds like a protagonist.

His face twists a little at the mention of imploding, though. That sounds graphic. "Because you're both... I mean, he's not being hurt by it? He can live normally?"

There might be something else special, like being super powerful and stuff. But it sounds like the real fascination is that he's just not plain dead like that. He's not sure how he feels about just destroying souls, either. If Shinigami can fix them, isn't it better to leave the job to them?
