"I wouldn't know, but I'll take your word for it," Sanae said with a laugh. He'd always thought of the universe as vast, especially given how many dimensions it could fit into itself. But it wasn't as if he'd ever traveled the universe that most people thought of.

He frowned at the Doctor's answer. Many beings like him on Earth...who were alien? How come none of them had ever decided to arrive in Japan--no, Tokyo? That city was probably (if pop culture was to be believed) the likeliest site of alien contact or Armageddon or what have you. "Huh...never knew that."

Sanae shrugged. "There's more 'round the country. We keep to ourselves, ya know, so ya won't meet another one of my type unless ya die and, uh..." How to put this? "...stay dead."
