An interesting concept could be that the square dance in the fanfic is a ritual in an anime world. The characters are initially reluctant to participate but as they start, they find that the dance has a special power. It can heal the land that has been damaged by some dark force. As they dance, the scenery around them starts to transform and become more beautiful.

They could use their unique powers and abilities during the dance, like a character with teleportation powers popping in and out during the formations.
