question

Guys, how is Shisui spelled in the original manga? I know that it can be spelled 死水, (which is hugely ironic,) but does Kishimoto-sensei spell it that way?

I figured I'd ask here since I want to know for the ItaShi story I'm trying to write for the advent calender, but if no one knows I'll ask in one of the general Naruto communities.
