Yukihara is a 17-year-old member of Class A. She is voiced by Satsuki Yukino.
Yukihira Sakurako is known as a renowned detective novel author, having published successful books while in high school. Other than that, she received her first award from the police in 3rd grade in elementary school.
At first, she had no plans to be a detective as she wanted to be a myster novel writer. At an unknown period of time, she changed her mind and enrolled to DDS planning to ascend in DDS on her own.
What most people don't know about her is that Sakurako is actually Morihiko Dan's niece.
Fiercely competitive, Sakurako is actually hot-headed despite her pretty look. In addition, she is quite stern on others and herself. She's very proud of her status as Morihiko Dan's niece and boasts that she will be the heir of DDS.
As the series progresses, she begins to gain interest in Kyu (the only one who knows her relationship with Morihiko), seeing him as a potential rival. She eventually gets her chance to challenge Kyu in a certain case. Unfortunately, she is kidnapped by a Meiosei member but Kyu manages to rescue her though not without the help of the rest of Class Q. To add insult to her injury, Kyu is the one who manages to solve the case. Despite that, she accepts her defeat and admits that Kyu is the better detective though she swears that she will challenge him again in another case. It is also hinted that Sakurako has a crush on Kyu. Like Megu, she is annoyed by Kyu's antics, resulting either pinching him on the cheeks or stashing him in a sleeping bag (making it look like a bag).
She eventually becomes good friends with Megumi and Kuniko, a newcomer of Class A, after a certain case in a train station.
