From episode 9. A mysterious force has been destroying structures around the Clamp school. Now, as Nagisa, looking ethereal in her purple kimono, begins her outdoor concert, it strikes again! Fortunately, Suoh is there to rescue her as the surrounding wisteria trellis is ripped apart. Good thing Nokoru "loaned" Suoh's bodyguard services out to help a lady in distress, and how fortunate for the two of them, as well. (Surely Nokoru knew just what he was doing.) ;-)
