Rikka loses her special treasure, a necklace that her dad gave her when she entered elementary school, and is desperately retracing her steps in order to find it. Amu and her Guardian Characters all help Rikka out, but Hikaru doesn't understand what all the fuss is about. Hikaru can't comprehend how something as trivial as a gift from someone can be so precious...
These episodes are so different Rikka is EVERYWHERE and you never see Rima or Yaya or Utau or <3Ikuto<3 and you don't see Tadase that much either....it makes me sad
