KI: [The Japanese fans] were very surprised. I think everyone was very surprised when Utena turns into a car. *laughs*

CS: When I first saw the Akio car come out... with Akio sort of...
KI: Riding the hood?
CS: Yes, the part where he gets on the hood. I seriously asked Mr. Ikuhara to explain what it was about. He said, "I wanted to express that he was an adult." (laughter from everyone) I was like, "What?"
KI: I explained to her that an adult rides the hood of a car with his top-half naked.
CS: Yes, and he continued to tell me that he's very rich so he owns a red car. I was like, "What?"
KI: I'm impressed you remember all that.
CS: I remember it quite well because it was such a shocker.
KI: I don't remember it at all. I really said that, didn't I?
CS: Every time these strange symbolisms would come out I would ask for an explanation, and each time I'd ask, he'd answer it with an interesting reply.

HM: So how did the idea of an adult riding a car hood pop up?
KI: You know when you're looking through a magazine or a photo magazine... how do I say this? The majority of people in photo spreads in magazines are people who you'd consider successful. For example, a famous star or a successful sports player. Currently it'd be people like... oh, but Americans might not know who he is because he's a soccer player. Like Nakata or... even Ichiro. These type of people usually ride red Jaguars and take pictures with their Jaguars. Every now and then there'd be someone overdoing it by putting their leg up on the hood. They emanate, "This is success!" or "This is what being an adult is!" There's this image where the ultimate adult would ride one!
CS: Really?
KI: Yeah, yeah! "The red Jaguar and I shall unite!" So he'd probably take his clothes off too!
CS: And how do you conclude taking his clothes off is uniting?
KI: Well, they're going to love one another... (laughter)
KI: With the red car.
CS: I see. So the red car and him are going to love each other?
KI: They're going to be in love.
CS: Do you mean he's going to become one with the car?
KI: Perhaps he is.
CS (more seriously): Do you mean that the symbol of success and him are going to become one?
KI: Yes, yes, yes! Yes, exactly.
CS: By the way, when you were in Los Angeles -- you were living in Los Angeles until recently, right?
KI: Yes, I was. Yes, just until recently.
CS: Didn't you buy a red sports car while you were there?
KI: I did. I bought a red sports car. My dream finally came true.
CS: So you became an adult when you went to the U.S.?
KI: Yes, I did. I rode around Hollywood with my red car?
CS: Did you get naked?
KI: No, I didn't. If I did I'd get arrested. It's too risky to do it.
CS: Oh really?
HM: Did you get on the hood?
KI: Eh?
HM: Did you get on the hood?
KI: I did it in stealth when no one was looking.
HM: I knew it!
KI: Might as well, you got to do it!
CS: But doesn't the hood get scratched when you do that?
KI: I made sure and wiped it later!
CS: Ah!
