To be honest, I've never watched Code Geass. The timeslot it aired didn't matched my schedule when I was in high school. I've watched Lucky Star and Clannad instead (Lucky Star is my No. 1 anime of all time btw).
On weekends the channel re-airs the five episodes of Code Geass. But I was too late since it's already like, halfway throughout the series. So I didn't bothered watching it. But I saw an episode accidentally and it shows Kallen. The moment I saw her on screen I was like, "Bazinga." Slim tomboy with big fat titties!
I know the premise of Code Geass, though. It's almost like a hypnosis fetish with Lelouch's eye powers. If I have that power I'd use it on Kallen and order her to use them badonkadonks to fuel my knightmare, if you know what I mean.
