Gato, Zabuza and others in “Unfinished Business”

If you're so eager to join your friend, go ahead, but you're not taking me! Not this time!

Zabuza

I won't be joining Haku. Where he's gone, I cannot follow.

Stay back! Stay back!

Zabuza

We wouldn't be welcome where Haku's gone to. Hell is where we're going, Gato! I can't think of a more fitting destination for a demon ninja, can you? I'm told there are many demons down there of all shapes and sizes. Oh yeah, I should fit right in. You on the other hand, Gato, well I fear. You're in for a long and very painful eternity! [kills Gato and turns to Haku's corpse] So this is goodbye at last. Not once did I ever thank you Haku. Forgive me for that. [starts dying]

[To Naruto] Don't turn away. When you live like a warrior, this is how it ends.
