Dialogues

• Thug: You're Yakuza, aren't you? What "family" are you with?
  Onizuka: Class 2-C, idiot.
• Kanzaki: Every now and then there are nights when I feel so lonely... and depressed. I wonder why someone like me was born into this world. I even wish I could vanish from this world... and pretend that I never existed...
  Onizuka: Stand up, Kanzaki. When I get negative thoughts like that, it usually means I'm hungry.
