Tear Jerker: Kaleido Star
In Kaleido Star, when Sora finds out that performing the 'Great Legendary Maneuver' with an almost broken shoulder injured Layla so badly that she won't be able to perform again in the Stage, she starts bawling. It's hard not to join in.
And what about Anna's Day in the Spotlight episode involving her fight with her father? When Jack performs the little trick with the hankie that he invented so many years ago to make little Anna laugh, I cried.
May Wong started as a pushy Spoiled Brat, but the episode featuring her fall from grace and subsequent Heroic BSOD is so well-done that you can't help feeling sorry for her. Then you actually grow to like her and are actually happy for her when she works to reclaim her glory.
Same goes to Leon, when he shows the first signs of his defrostment by panicking as he sees Sora almost being hit by a car just like it happened to his sister Sophie, pulling her away from danger in a Diving Save and, right after this, looking at her tenderly and asking "...Sophie, are you hurt? I'm so glad you're alive...", mistaking Sora for Sophie.
