Klein is usually very professional and formal with his speech. He speaks loud and clear so that his employers can always understand him and he doesn't have to waste their time repeating things. While he normally can be described as a typical butler, his range of expression is very wide, from happy to angry to bashful, and many others.

I read through the four chapters that make up the Volume 0.5 that is being cast, totaling up the amount of words this role would say, and how long it took me to read them to myself. The estimated word count is that number rounded up to the nearest hundred and the total time rounded up to the nearest minute. As I was keeping time, I would round up by a second or two. So the count and read time aren't exact, but should be very close.
