Wonderful Channel is a dream channel where anyone can start simply and become an idol. It is a common dream for girls to open their own channel and become an idol. Momoyama Mirai and Moegi Emu, first-year students at Twinkle Hill Middle School, opened their own channels to compete with the popular idol Anna Akashina in the school. At the same time, Aoba Rinka, an excellent student who is very familiar with Wonderful Channel, also joined the team, and the dream idol channel belonging to the three of them began.
