Brother, friend… I earned many titles for a mere copy. But no matter what I’m called, I cannot lose the sight of my duty. My duty is not to live, it is to protect you. I cannot live for the sake of another, but grant me the right to die for a friend and to die for my brother.
Gintoki: Your life is not something you can get rid of it that easily anymore. You’re something more than just someone who protects Tama. All the protection you gave made the people want to protect you. All together, just like leukocytes.
King Leukocyte: I had to be the copy of such a difficult man… Even now I can’t offer any words of gratitude or tears… In a situation like this, what would you do?
Gintoki: I’d smile.
Ep. 170 in the end, when the King is injured and Tama.
