Appearing with their group in Saga Rock, they only make a presentation during the episode while Ai watches them, since it was their previous group.

Episode 12
Appearance at the end of episode 12, when Ai sings her part, again indicating a future relationship.

Episode 15
Appearing for the first time in the second part of the episode, Shiori arrives with her group at Saga at Kyushu International Airport, upon arrival she is received by a large fan due to her fame throughout Japan. Her speech in front of her press is inspired by the fact that nothing is eternal in life and that Iron Frill are unique and incomparable, this being an indirect reference to Franchouchou.

She later appears at the end of the episode by following Ai to her place of work and mentions that she has been following Franchochou for a long time (presumably since Arpino) and that she sees that Ai does not want to be in the group because little by little She has been distancing herself from the other girls, without letting Ai Shiori speak, she aggressively proposes to join Iron Frill and leave her old-fashioned group Franchouchou, which will trigger a future drama although she does not know that Ai cannot leave the group because of her undead zombie condition.

Episode 16
Now in the new inaugurated stadium of Saga Arena, she prepares for her new success NOPE!!, proud of herself is interrupted by Yui, the voice of reason from Iron Frill who tells her that she found out that she tried to recruit a number 3 of Franchouchou, Shiori replies that she will not be able to shine in a place like Saga and that with Iron Frill she will be better, Yui tells her that she knows that the reason is her admiration for the late Ai and points out that she leave the past in the past. Before the event, she talks to Ai about Franchouchou's performance to which Ai tells her not to underestimate the group since they have not stopped improving since they started, Shiori doubts this and goes confidently to the concert, however she is surprised by the performance electrifying of Franchouchou and we see that his attitude with number 3 is because it reminds her of her childhood idol Ai Mizuno. Although she later tries to re-recruit her, she is rejected by Franchouchou. After her national tour she recognizes Franchouchou's performance calling them their worthy rival. Shiori/Sipnosis
