Amu and Tadase are on their way home when Yoru sends Amu a picture of Ikuto sleeping, and causes her to blush. When Tadase asks Amu to join him to the park, she tries to hide her nervousness. Ran then Character Changes with Amu to help her express her honesty, and inefficiently catches Rikka's attention. Rikka learns about Character Changing and views Amu's different personality changes: Su turns Amu into a girly maiden, Miki turns her into an artist. Then, they ask Diamond to Character Change with Amu, because they had never seen it before. Diamond fulfills their request and Character Changes with Amu, thus turning her into a sparkling person, much to their disappointment. Later, Amu runs to the park to meet Tadase. Tadase expresses his feelings to Amu. Ran then Character Changes with Amu to make her express her feelings just as Rikka arrives to watch the occasion, but Amu accidentally destroys a sand castle that two kids had made. Miki then Character Changes with Amu again to remake the sand castle, but her passion to art causes her to make an overwhelmingly big castle. Rikka grabed and asks Miki to help her finish an artistic homework of clay by Character Changing with her. Miki then tells her that Guardian Characters can only use Character Change on their masters, which disappoints Rikka. Just then, Amu, Tadase and their Guardian Characters arrive. Amu volunteers to help Rikka with her homework. And though Rikka felt hopeless at first, Tadase tells her how Amu's desire to do her best makes her special, which encourages Rikka to direct her energy into doing her best. Eventually, Rikka is able to make a catfish out of clay. Rikka accidentally says the word "prince" in front of Tadase, and unwittingly triggers his Character Change. The changed Tadase forces Rikka to give him ´massage, and Rikka finds the scary side of Character Changing, despite she found it fun at first.
