Airing Date plz! Can't remember the scene for now! :ONshock: :-P
Hmmm...Maybe it wasn't Utaban? It was one of the music shows, I'm prolly wrong about which one though.
Rika is graduating and appoints Sayu as her "successor", so Yumi goes on this spiel about how she's the "only true beauty here" and such. I'm sure you've seen it TB, it's been discussed in this thread before but I'm too lazy to dig it up
Anyways...that was the birth of Sayu's self-obsessed character. To me it seems like an obvious joke but it certainly spawned some haters that took it too seriously.
