Chronology Edit

Season 1 Edit

Episode 2-4 Edit

Also, Yuuko is shown to dislike Reina Kousaka from as early on as when Reina plays her trumpet for the first time, probably due to the fact that Reina can play better than Kaori.

Episode 5 Edit

At the Sunrise Festival, Yuuko (along with most band members) feels nervous after she witnesses Rikka High School's performance. Kaori Nakaseko sees this and tells her to take a deep breath. When Reina suddenly blows her trumpet as an attempt to calm everyone down, Yuuko tells Reina that they are not allowed to make noise while waiting for their turn. Reina says "Sorry" and brushes her hair in response. When Kitauji High School Concert Band's turn comes, Yuuko and other band members perform what they have been practicing and manages to surprise the audiences/observers.

Episode 7 Edit

Everyone is preparing for the incoming audition to select a member for competition team, one day after the practice ends, Yuuko asks Kaori Nakaseko to go home with her, but before Kaori can answer, they hear Reina Kousaka play the trumpet solo part of Crescent Moon Dance Yuuko talks to Kaori about why Reina would practice that part when the band already has Kaori for the solo. Kaori tells her that it's okay since there is no rule that prevents the first years from practicing that part and asks Yuuko whether she has been ignoring Reina or being mean to Reina. Yuuko answers no and tells Reina to clean up since practice is over. Later, Yuuko is shown to have a little fight with Natsuki Nakagawa as Yuuko tries to leave the room.  Seeing this, Riko tells Kumiko Oumae that Natsuki and Yuuko don't really get along.

Episode 10 Edit

Yuuko hears the rumor about Noboru Taki knowing Reina Kousaka long before she enrolled at Kitauji High School Concert Band's and Taki-sensei might be biased toward Reina which might explain why Kaori Nakaseko doesn't get to play the solo part. Even though Kaori tells Yuuko to discard that rumor, Yuuko decides to ask Taki-sensei about it in front of all band members. Taki-sensei tells her that he evaluates everyone equally but he confesses that he has known Reina since middle school since he is a friend with her father. 

When Yuuko tries to ask something more, Reina interrupts their conversation and tells Yuko to stop insulting Taki-sensei. Reina says that she got selected because she is better than Kaori. Reina's words greatly enrage Yuuko, leading her to yell at Reina. Kaori manages to stop the fight before things get worse.

Yuuko's action causes an uncomfortable/uneasy atmosphere in the band in the following days and everyone starts to lose their motivation for the competition.

Later, Natsuki Nakagawa tells Yuuko that this situation will only hurt Kaori Nakaseko which makes Yuuko falls deeper into the sadness.

Then, Yuuko bows to Reina and asks Reina to purposely drop the audition. Yuuko explains that in the previous years Kaori didn't get to play a solo part because of the seniority system and this year will be Kaori's last chance to play solo. She also tells Reina that Kaori also tried to resign from the competition in order to stop the first-year members from quitting the band. However, Reina doesn't care about any of this as it doesn't have anything to do about her and walks away.

On the day of re-audition, after Kaori and Reina finish their performance, and the band starts voting, it turns out that only Yuuko and Haruka Ogasawara clap for Kaori while only Kumiko and Hazuki Katou clap for Reina. Taki-sensei then asks Kaori "Will you play the solo part?" Kaori, knowing that Reina is better than her, declines his offer and says that Reina should be the one to play solo part.
