Yahagi Sayuri tends to be pretty black & white when it comes to chemistry with other personalities. It either works, or it doesn't. When it doesn't work, she's pretty low tension. For whatever reason, Itou Kanae raises her energy level, so they work well together. It's strange because Itou Kanae isn't trying to cause this. In fact, she's often perplexed as to why Yahagi Sayuri gets into high tension mode.
This has nothing to do with this CD, but these two, and probably many more, are somewhat traumatized by working with Kaneda Tomoko. For example, many fear doing a radio show with her, or appearing at an event with her. Why? Because Kaneda Tomoko is uncontrollable. Listening to these two shiver in fear of the upcoming event made me realize how well Mikami Shiori handled her as a guest in another radio show.
