Dream Festival!

Kanade Amamiya, a high school student known for his cheerful personality, is scouted into the idol industry by Haruto Mikami, a well-established figure in the business. He joins D-4 Production and meets his fellow classmates Shin Oikawa, Junya Sasaki, Itsuki Katagiri, and Chizuru Sawamura, all of whom share his aspirations to become idols. The agency groups them together for the Dream Festival, where they compete against other artists for the audience's attention and support. To succeed, they must collect Dorika cards from the audience to create their stage outfits and build a strong bond of friendship and trust.
