Kakihara: Wow... this is great!
Kakihara: Yup. That's Boss Anjo's, all right.
Kakihara: Listen, when you're giving pain to someone, don't think about the pain that person is feeling. Just concentrate on how good it feels to be causing someone pain. That's the best thing you can do for a true masochist!

Kakihara: Damn... Nobody left to kill me.
Ichi: From now on, I'll beat you up.
Sailor: You will?
