Mason and Kira in “Unfinished Business”

Mason

Okay, well, I've been doing some reading on kitsunes...

Kira

[confused] Why?

Mason

'Cause I met one?

Kira

Oh. Right.

Mason

Do you know why people in Japan answer the phone "moshi moshi?"

Kira

"Moshi" means "hello."

Mason

Yeah, but there's a reason why you have to say it twice on the phone. Because, according to Japanese folklore, fox spirits have difficulty with language. And the way that you prove you're not a fox? When you answer the phone, you say "moshi" twice. The important part is "moshi moshi" confuses kitsunes because it's a language trick. So is the book-- you know, it's just one long language trick.

Kira

That's why I can't read it?

Mason

It's affecting the fox part of you, confusing it.

Kira

I swear that wasn't me.
