Shinigami, Karai and others in “Unfinished Business”

Karai, I bring you the red-haired girl's tanto blade.

So, Splinter finally made April a kunoichi, eh? Kind of a shock.

Yes. She seems so frail and clumsy when you first look at her, like a silly red bird.

Well, this kunoichi tracked your butt down, Karai! What are you doing anyway!!?

None of your business! Just go!
