Yuko (Japanese: ユウコ Yūko) is a recurring character in the Pokémon Adventures manga.
Yuko debuts in the Black 2 & White 2 chapter as a student in the Aspertia City Trainers' School. Yuko is first seen with Yuki and Maya greeting Blake as he heads to class. When Blake, Leo, and Hugh are punished by the new teacher, Cheren, for disrupting the class, Yuko defends Blake by blaming Hugh for everything. Later, Cheren has the class split into two gendered groups and has them battle each other. Yuko is eventually defeated, but congratulates the new student, Whitley, for winning the girls side and obtaining a Pokédex.
After an attempt to try and get Whitley closer to him fails, Blake returns to the school while everyone is participating in a Berry planting class. Seeing Blake carry Whitley like a princess shocks Yuko and the rest of the class.
Yuko later travels with the class to Pokéstar Studios on a class trip. She, Yuki, Maya, and Whitley browse the area and wonder what kind of movie they should participate in. Although reluctant, Whitley is assisted by Sabrina, who uses a Spoon of Destiny to pick a movie for her. After leaving, Yuko and the others realize that Sabrina is actually a famous actress. Once the trip ended, Yuko and the other girls excitedly wonder what to do for the upcoming culture festival at their school. The girls' chattering annoys Hugh, who questions why they bother attending school if they don't focus on getting stronger. Yuko berates Hugh's abrasive personality, and states that she feels sorry for his younger sister for having such a bad brother. Hearing this infuriates Hugh into attacking the girls with his Vibrava before being stopped by Leo. Yuko and the others angrily leave as they hope that Hugh gets expelled.
Later, Yuko competes in the Autumn Choir Tournament as a member of Team Jigglypuff alongside Blake, Whitley, Hugh, Leo, Yuko, and Maya. After a hard battle against Team Sawsbuck, Team Jigglypuff emerges as the winners of the competition with the help of Blake's Dewott. As a reward for their performance, Roxie has her father take the winning team and their class to Castelia City to participate in the Unova Choir Tournament.
After traveling on Pop Roxie's boat, the class arrives at their destination. Shortly after stepping onto land, Roxie discovers a member of the executive committee for the Unova Choir Tournament whose Karrablast was stolen by a group of people. While Blake, Whitley, Hugh, and Roxie go off to find the thieves, Yuko and the others stay behind to look after the committee member. When the class meets up with each other, Yuko, Maya, and Yuki attempt to tell Cheren about the situation, but are interrupted by Hugh. Hugh reveals to everyone that thieves were actually remnants of Team Plasma that have returned. He also reveals that one of the girls in the class is a member of Team Plasma and presents a pendant containing a picture of N he found as proof. Hugh tells everyone that he plans to leave the Trainers' School to continue his pursuit of Team Plasma, but is stopped by Whitley, who was keeping herself hidden. The class, finding Whitley's behavior suspicious, begin to suspect she may be the person Hugh was talking about, but are put to sleep by Foongy's spores.
Yuko, Cheren, Roxie, and the class later awaken at the Marine Tube. There, they encounter Benga, another student at the Trainers' School who was suspended on the first day of class for picking a fight with Blake, Leo, and Hugh. Benga reveals that he and Marlon took everyone to safety after finding everyone lying unconscious just after witnessing Castelia being frozen by Team Plasma's flying ship, the Plasma Frigate. While Cheren discusses how to deal with Team Plasma with the others, Yuko, Maya, and Yuki assist N's Zorua, who had disguised itself as Whitley to fool the class into thinking she never left. Though they remembered Hugh's earlier claims, the three choose to believe that Whitley isn't a member of Team Plasma under the assumption that she wouldn't be there helping everyone if she was.
