Because it was senshuraku, everyone got a penlight when they entered the theater, along with instructions to wave it during a certain part during the finale.  It was red and said “Le Rouge et le Noir.”  I love these sorts of things *g*  I was a bit surprised since I thought it only happened at a top star’s sayonara show, but I’m certainly not complaining.  Apparently the Tokyo branch of Touko’s club organized it ^^
