This is the 5th song in the series "Star Girl and the Illusory Musical"
A kiddish girl who is sick of growing up wishes to forget the adult world and become a carefree child again. The city grants her wish and, after accessing the core of the city, she returns to being a kid. After a "shooting star" grants her and her friends wish to have something to play, she and her friends begin to use the junk received to build a paradise for the kids. They do this without realizing that they were repeating the system and world of the adults. In the end, while trying to return to her childish world, she ends up jumping into a sewer that was under construction. While in parallel, Rho and Lambda, the two from ANTI THE∞HOLiC, contemplate how the events unfold while commenting about them.
