Yuuko became a successor when she was at least 14 years old. Along with the rest of AKB0048, she holds a secret concert in an abandoned mine on Lancastar. DES tried to stop them, but was quickly defeated. During the performance of Shoujotachi Yo, she seemed to notice Nagisa, Orine, Yuka, and Chieri and waved to the girls. She also took an active role in combating the forces of DES, throwing bombs at them and attacking with spirit.
4 years later, Yuuko and the rest of AKB0048 appeared on a hologram card that Yuka had received, telling them how to auditions.
Later, her and the rest of AKB0048 came to the rescue of the auditioners when DES took over a ship in order to search and capture the auditioners. She managed to save Chieri from a fallen chandelier that had trapped her and lifted the it with ease just by singing the Heavy Rotation.

In Episode 7, she trained Chieri as her stand-in. During the lunch break, it is shown that she likes green steak peppers made by Chef Papa. Hearing that, Chieri asks for extra pepper even though she doesn't like them because she wants to be more like Yuuko. She then follows Yuuko walking around the city. Yuuko then later goes to unknown place. Later on, her Mayuyu and Yukirin hear Takamina saying that Kanata should be a successor and that she'd tell Tsubasu-san. Yuuko hugs her and kisses her cheek, saying that she will join her, too. Yukirin and Mayuyu alos join her. When they arrive at the holy grounds, they see the kirara of success. Then, images of the the them and the original member that they have succeed appear.After the original Takamina appeared, instead of showing , Kanata appeared.

Yuuko got very angry from what Tsubasu and yelled at her stating that No one could ever replace Takamina. Then all of them exit.
In the next episode, Yuuko is seen when Takamina wakes up from her long-sleep.
Season 2 - Next StageEdit
Yuuko takes a more prominant position in Season 2. Her desire to become Center Nova only grows with the announcement of the return of the position and the return of the General Elections. Early in the season she declares all members of AKB0048 (successors and understudies) to be her rivals and adds emphasis to Chieri and Nagisa. In the early results of the General Elections, she ranks 2nd losing to Takamina. In conclusion to the General Elections, Yuuko ranks 1st and vows to become Center Nova and outshine Acchan the 13th.
After the elections, she begins to doubt herself because of the radiance produced by Nagisa and Chieri. When the rumor is revealed that someone will succeed Acchan, she begins to doubt herself. As a test to see who has a chance of becoming Center Nova and/or Acchan, she takes pictures of all of the members only to find nothing (meaning she could have no competition or that she is not meant to be Center Nova and as such can't detect other members who will take the rank).
On the attack on Akibastar, she became Center Nova, but is unable to control the power and energy of Center Nova and disappears to the other world, where Acchan and the others are.
In Episode 26, Niji no Ressha is performed, Yuuko admits to Acchan the 13th that becoming Center Nova was never her true goal, and that she in reality, she just wanted to sing alongside her heroine, Atsuko Maeda. Acchan says that Atsuko Maeda has always been by her side. Later it is revealed that Nagisa is in fact Maeda Atsuko the 14th. She is then later overheard singing along to Kaze wa Fuiteiru, and appears through the kilala drive-like gate and continues singing with the successors and understudies.
