Voice Actress: Amanda Winn-Lee (https://youtu.be/ND7Sr58HjYE)

She is another of Yu Narukami’s classmate at Yasogami High School in Inaba, and her family runs the local hot springs inn called the Amagi Inn.

Yukiko's family runs a famous hot spring inn, the Amagi Inn in the town of Yasoinaba, often mentioned in the news as "the treasure of Yasoinaba." Yukiko is expected to succeed the family business by becoming the manager of the inn, and is always busy training herself. Due to this, Yukiko is often oblivious towards romantic feelings, and tends to misinterpret others' conversations. Despite her apparent willingness to inherit the inn, Yukiko is deep down falling under stress as a result of being branded the next owner of the inn. Because of her obligation she often goes home quickly after school is over and may even skip classes.

During an interview, Yukiko wears a pink kimono. That night, an image of her wearing that kimono is shown on the Midnight Channel. Worried about her the next day, Chie tries to contact Yukiko's cell phone, as she hasn't showed up at school. The contact fails, and Chie instead receives Yukiko's voicemail. Yosuke would later suggest Chie to call the Amagi Inn, where Yukiko finally responds. She explains that she is busy catering at the Inn, and thus had to skip school. 

Still worried, Yosuke suggests that Narukami should tune into the Midnight Channel tonight as well. That night, a show called "Princess Yukiko's Search for Prince Charming" is shown on the Midnight Channel, where Yukiko dresses up as a princess on a journey to "score" with a "hot stud," or Prince Charming. As Yukiko's behavior in the TV was rather bizarre and unlike how she would normally act, Yosuke calls the protagonist and suggests that they meet up in the Junes Food Court the next morning. There, Yosuke, Chie and Yu decide to venture into the Midnight Channel once again.
