Yuuri was born without her mother. Her father lived in Akibastar for a very long time, so he had no surprise if his daughter will join AKB0048, which she accepted one day, to whilst feeling like that will be a good idea. So she joined the 154.5th Generation.
Unlike Ayaka, Yuuri was barely seen during this fight. After hearing the news of Miyagi's death, Yuuri felt glad she didn't fight the enemies, but she wanted to change the world with music. So, she tries to work harder to be less fearful.
Yuuri tried her best to join Karin for the succession, but she couldn't help being cold hearted. She protected Karin a lot but soon, it will be Karin protecting her, and she felt upset on it. Now, she has calmed down, and then starts to not give up. This wasn't the same for Aoi.
Fellow generation-mate. The two are on good terms. Calls her by "Aochan". Unlike Karin's succession, she's looking forward to Aoi's succession.
Fellow generation-mate. Calls her by "Karichan". Considers to be her rival. When she heard Karin was succeeding, she started to feel cold around her, due to the fact she's disapointed that she's not the first girl from their generation to succeed. But after that, she felt alright. She's aiming to succeed and be alongside her one day.
Fellow-generation mate, and knows a lot about her since they first met. Calls her by "Ayachan"
Very scared of her, especially with the haunting phrases she hears from Kaoru.
Her only family member, since her mother died whilst giving birth to Yuuri. An Akibastar resident his whole life, he had no surprise that Yuuri wants to be part of AKB0048 as AKB0048 was extremely popular. Yusuke is a teacher at the Star Soldiers School, and considered to be a carefree but cold and timid man. He cares for his daughter, but not very protectively. He believes that everyone has enemies, and wants Yuuri to understand that she has an enemy in DES.
