"I don't talk about other people's business," Koumyou tells him simply. And it's true, even when it would be a lot easier on him if he did, for any reason... he's just not the type.

"I haven't been Houmei in twenty three years. I'm Koumyou Sanzo, or Sanzo for short."

Saying it that way has led to a lot less people trying to use his holy name by itself. He can count the number of people allowed to do that on one hand, with fingers to spare, and only one of them is on this train.
