1x20 - Shugo Chara!

Kukai introduces Amu, Nadeshiko, and Yaya to his childhood friend, Sion. Sion is an aspiring pianist and will be leaving town soon to challenge her skills. On the way home from School, Kukai runs into Sion as she searches for a four-leaf clover. The next day, Amu encounters Kukai at a mall as he looks for a farewell gift for Sion. While they look for a gift, the two Guardians run into Sion. Meanwhile, Utau puts on a concert at the mall, and several X Eggs are extracted from the crowd, including Sion's. Amu runs into Utau and meets with Utau's Guardian Character, Il, while Kukai is busy rounding up the eggs. Amu finds Kukai and Character Transforms into Amulet Spade to cleanse the eggs. Just before Sion leaves for her studies, Kukai arrives and gives Sion her farewell gift, a four-leaf clover.
