As Christmas approaches, Ichigo grows depressed as she thinks about how she is regularly lying to Masaya to hide her being a Mew Mew. Zakuro invites her to go shopping with her and tells Ichigo that since she cannot open her heart, she should give Masaya something that reflects her feelings. Ichigo chooses a necklace called "Tears for Christmas." She is still initially reluctant to face him, but finally arranges to meet him at the big Christmas tree in Odaiba. While she is waiting, the aliens attack. When Ichigo transforms, her emotions cause mew aqua to materialize at the top of the tree. Joined by the others, the Mew Mews prepare to fight the aliens to acquire it. (thetvdb.com)
