Yuu recounting a conversation with her father Tetsuo about the stars in the sky and the fable associated with the decennial Dream Comet gives way to a news broadcast about the Dream Comet as Yuu finishes making a crepe for Midori that sets the stage for Yuu to prosecute a divergent concourse regarding the existence of Mr. Dream with Toshio who plans to observe the Comet that night with Midori. Later that evening while staring up at the sky, Yuu explains her childhood prologue with Toshio whose detection of the Dream Comet becomes the forum for Mr. Dream to manifest himself before the astonished Yuu as he explains the adventure ahead of her that night. Yuu's adventure with Mr. Dream begins with some elements of »Alice in Wonderland« that enable Toshio to spot Yuu well enough to give chase after her; while unable to follow Yuu to the dimensional area where the secret clubhouse is located, Toshio's anxiety for Yuu's welfare is a potent deus ex machina that ultimately adds enough elements of »Cinderella« to bring the evening excursion to a conclusion that leaves Yuu feeling satisfied with a healthy perspective of the circumstances; even if the complex logistics of reality do not always work out in her favor, Mr. Dream leaves behind a wonderful consolation prize for Yuu: a Toshio that happily accommodates her childish dreams.
Yu attende con ansia l'arrivo del Signore dei sogni, che il padre le ha raccontato anni prima. Caso vuole che la notte stessa una cometa passi per la Terra e il fantomatico uomo regala-sogni invita Yu ad una notte in cui far avverare ciò in cui crede. Al mattino, purtroppo, ogni ricordo sarà svanito.
