"Is there a reason the manga is called Bleach, or is that a secret?"

KT: The Soul Reaper-the color that you associate with the Soul Reaper is black. But "black" is too straightforward. So I thought about "white," but just white is too simple. So if you put "bleach," somebody can associate that with white. So that's how Bleach came.
