The Arduous Path of Truth! Kairi Returns!.The students are taking a trip to a summit for two days. Amu at first doesn't want to go, but thinks about the things she'll be able to do with Tadase and changes her mind. It turns out one of the Chairmen is Kairi. Tadase, Amu, and Kairi sit in silence. The Guardian Characters break the tension. After that, they decide to go to the lake the next day. While Kairi gets water, he overhears some girls saying that Tadase and Amu are a cute couple. Later, Amu overhears Kairi saying he doesn't want to see Amu anymore, because of what he lacks. Amu gets angered by this, and asks why he can't stay the way he is. At the lake, a little boy, Saito, ends up getting lost. Kairi, who recovered and took Amu's advice, starts searching for him, while Amu and Tadase already were. Amu finds Saito later. A storm comes, and a tree falls over, resulting in a log targeting Amu, Tadase, and Saito. Kairi then Character Changes in time. Tadase and Kairi transform into Platinum Royale and Samurai Soul to stop the logs. The summit ends with everyone safe. Kairi apologizes to Amu, and Amu starts blushing again. Kairi tells Tadase that even though he's far away, he shouldn't let his guard down.
