Lots of great moments in this episode. I'm glad Sei is sticking around - she brings out the best in Yumi (and vice versa).

I wonder how many more episodes will pass before graduation? It's not that I'm ready to see Sei, Youko, and Eriko out of the picture; it's just that, until the three graduate, Yumi and Sachiko's relationship will probably continue to stagnate. That, and I'm looking forward to meeting the new characters.
