5 episodes left to watch and review! I wonder what math problems are waiting to be solved. :3
This episode starts out with Nina and Sayuri fighting. Supposedly, Sayuri threw the mentaiko bread to Nina, but it ended up flying out of the window instead. Sayuri was just trying to help, but Nina is upset with her. Sayuri ends up saying a whole bunch of mean things about Nina and Nina says Sayuri should apologize to the god of mentaiko. ^_^" (Even though her bread was safe and sound on the window ledge. @.@) Since Sayuri stormed off, Kazuki runs after her and ends up following Sayuri into the "Elite Area". Sayuri wants Nina to apologize to her, but doesn't at the same time since that would be so unlike Nina and Sayuri doesn't want to see that kind of Nina. (What complicated feelings, eh?)
Once Sayuri actually lifts her head and clears her mind a bit, she realizes that they are in forbidden territory, but Kazuki is confused. They try to leave, but get caught in the process by 3 elite students, who are Yotsuya Yuko (played by Hagiwara Mai from ºC-ute), Komaba Satoko (played by Nakajima Saki, also from ºC-ute) and Mita Tomoko (played by Okai Chisato, also from ºC-ute --> This means that all members from ºC-ute have been featured in Suugaku Joshi Gakuen!)
These elite students have classical music playing behind them and lift their glasses with their index finger one by one, saying how they don't permission to be in this special area of the school. Kazuki is still confused and Sayuri begins to explain that the school is divided into Inner Circle and Outer Circle. The elites are part of the Inner Circle and they are very rich (get all the nice stuff: teachers, classrooms, etc), and everyone else is part of the Outer Circle. Because Sayuri wasn't able to explain why they were in their area, Sayuri and Kazuki get tied up. Satoko talks about how Sayuri may be helpful to them for the Intramural Math Battle, which pits the Inner Circle vs the Outer Circle students. Whichever side wins will be able to have additional classrooms, etc. When the elites find out that Kazuki is the "dumb transfer student", they let him go and Kazuki is extremely upset.
