As the screen tells the fans to have lots of fun, Kanon prepares herself, jumps out and begins to sing, starting the concert. Meanwhile, at the Katsuragi household, Elsie is dancing to Kanon's songs and quickly tunes in to Kanon's show. After the show, Elsie hugs the TV, expressing her desire to meet Kanon as she rarely shows up to school. Elsie then sees a newspaper ad for an audition to be Kanon's little sister and excitedly flies to participate. After the concert, Kanon is resting when Okada mentions the audition, which Kanon has been anticipating, expressing she is a little shy about it. Okada also notes Kanon's show has gained her more young girl fans. Kanon then sneezes, and Okada advises her to take a quick shower. Elsie tries to enter the audition but is turned away for not registering earlier and appearing to be Kanon's age. Elsie insists she is at least 300 years older. At this time, Elsie's sensor goes off, and she sees a runaway spirit entering the studio. Elsie tries to enter but is stopped. However, Elsie uses her hagoromo to subdue her subduers.
