Yuuko Yoshikawa (吉川 優子 Yoshikawa Yūko) is a character in the Sound! Euphonium series. She is a second-year student who plays the trumpet.

Appearance

Yuuko is a teenage girl, who looks younger than she actually is, with shoulder-length dirty-blond hair that has evenly cut square bangs, light-bluish-green eyes, and a pale-yellow bow headband.

She wears the standard Kitauji High School uniform.

Personality

Yuuko is a nice, friendly and cheerful person who is also shown to have confidence, determination and a strong personality. She can openly and confidently show others what she is thinking through her actions, her facial expression, and her words.

However, Yuuko is also an emotional person, as she can easily get annoyed or angered when something didn't go in the way she wants it to. Yuuko does acknowledge these flaws of hers and tries to improve herself, and gets over her own pride for the success of the band.

By nature, Yuuko will put great importance in the people she cares about, willing to do anything she can to ensure their happiness and well-being. Sometimes, this leads her to make some mistakes, but other times it elicits very noble actions from her. Conversely, Yuuko behaves acerbically towards individuals she dislikes or someone she perceives as a threat to her cherished friends.

Chronology

Season 1

Episodes 2-4

Yuuko is introduced as a second-year trumpet player who shows a great amount of admiration for Kaori Nakaseko (Yuuko's section senior), as she pounces on every possible opportunity to walk home with Kaori. 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

At the Sunrise Festival, Yuuko (along with most of the 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 apologizes 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 manage to surprise the spectators.

Episode 7

Everyone is preparing for the upcoming audition to select members for the 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, but 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 bullying Reina. Yuuko denies it, and tells Reina to clean up since practice is over. Later, Yuuko is shown to have a little fight with Natsuki Nakagawa on her way out of the room. Seeing this, Riko explains to Kumiko Oumae that Natsuki and Yuuko don't really get along.

Episode 8

On the festival day, when the practice ends, Yuuko tries to invite Mizore Yoroizuka to go to the festival with her, but Mizore declines her offer, so Yuuko ends up going to the festival with Natsuki Nakagawa and Tomoe Kabe instead.

Episode 9

Yuuko passes the audition, but is shocked to learn that Reina Kousaka will get to play the solo part instead of the crowd favorite Kaori Nakaseko.

Episode 10

Yuuko hears the rumor about Noboru Taki knowing Reina Kousaka long before she enrolled at Kitauji High School Concert Band. It means that Taki-sensei might be biased toward Reina, which would explain why Kaori Nakaseko doesn't get to play the solo part. Even though Kaori asks Yuuko to tell the others not to spread that rumor, Yuuko decides to ask Taki-sensei about it in front of all the band members. Taki-sensei tells her that he evaluates everyone without prejudice, but also confesses that he has known Reina since middle school, as their fathers are acquainted.

When Yuuko tries to ask something more, Reina interrupts their conversation and tells Yuuko to stop insulting Taki-sensei. Reina says that she was selected because she plays 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 actions cause an uneasy atmosphere in the band in the following days, and everyone starts to lose their motivation for the competition. Taki-sensei decides to resolve this problem by presenting all the band members a chance for a re-audition. Kaori grabs this chance and asks for re-audition.

Episode 11

Yuuko eavesdrops on Reina Kousaka's play. When Yuuko sees Kumiko Oumae going to invite Reina out for lunch, she asks Kumiko's opinion on Reina's play. Kumiko says that Reina sounds very good and deserves to play the solo. Yuuko agrees with Kumiko, and says that it's unfair that a first-year can play that good, before walking away.

Later, Natsuki Nakagawa warns Yuuko against doing "something stupid", else this situation will only hurt Kaori Nakaseko, which makes Yuuko fall deeper into sadness.

Then, Yuuko confronts Reina, bowing before her and asking her 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 do it. She also tells Reina that Kaori tried to resign from the competition in order to stop the first-year members from quitting the band last year. However, Reina says that it has nothing to do with 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 whether she will play the solo part. Kaori, knowing that Reina plays better than her, declines his offer and says that Reina should be the one to play it. Upon hearing this, Yuuko finally breaks down and cries out loud.

Episode 12

On the morning of one day, Yuuko and Kaori Nakaseko greet Reina Kousaka, who apologizes for her behavior during the audition, and Kaori apologizes to Reina in turn. Yuuko is surprised by Kaori's action. During this time, Natsuki sneaks behind Yuuko and surprises her.
