Ninja Assassin (2009)

Ozunu: Weakness compels strength. Betrayal begets blood. This is the law of the Nine Clans.

Tattoo Master: The irizumi does not hide the skin. The tattoo reveals the nature of the man and illuminates the four noble professions in the Book of Five Rings: the warrior, the artist, the merchant, and the farmer. If there is a conflict between the needle and the skin, between the mark and the man, then perhaps the path you have chosen is not the path for which you're suited.

Mika Coretti: I know you can't hear me, so I'm sure this doesn't matter but I'm going to say it anyway. I'm just a forensic researcher. It's like a fancy way of saying I'm a librarian. By myself I can't do anything to help you, but I wanted to thank you for saving my life. And I hope you can forgive me for this.
