To Be Decided

To Be Decided is the twenty-fourth and final episode of the Lucky Star anime.

Plot
Konata and her friends prepare for the school's cultural festival. Patricia decides to have the girls do a cheerleading session set to the show's theme song, which hassles the girls between preparations for their class' cultural displays and preparations for the routine. At first, Patricia has a hard time trying to convince her friends, but then she bribes Konata with a ticket to an Aya Hirano event, where people could shake hands with her. Konata gets her friends to help out, and even though Kagami is initially against it, she becomes the most enthusiastic of the bunch to do the routine. Akira Kogami has been invited to the school as a special guest and Minoru is in charge of showing her around. On stage Akira is doing a performance, but she and Minoru still despise each other and argue in front of the entire audience. At the end of the day, Konata, Tsukasa, Kagami, Miyuki, Ayano, and Misao reflect on their last cultural festival. The next day, at the opening of the festival, the girls get ready emotionally for the dance, and as the curtain rises, the screen fades to white.
