Wai! One of my new favorite cels ^_^  Signed by Yuu Watase at AZ 2002 - she even drew a little heart over Yuuhi and Chidori!  I just love it!

Ah, yes, Yuuhi is once again totally thrilled to have Chidori hanging all over him :P  And then of course we have Q-san with a cup on her head...ummm,k.

Matching background, from episode 10.  Also in the flashback sequence in Episode 19.
