Our world is full of joy!!

The trio of Rika, Miria, and Kirari make their debut as Dekorationt and even do a tie-in with the fashion brand Pika Pika Pop. The unit does fine with a PR event, but Producer feels they can involve the audience more. While thinking of ways to do just that, the trio takes a breather in Harajuku, but when Producer gets separated from them, both sides look in all the wrong places for each other. The clock is ticking too, since the next event starts soon, so never mind engaging the audience, Dekoration may miss the whole thing!
