Touka Miyashita (宮下 藤花, Miyashita Tōka) is the alternate protagonist of the Boogiepop Series. She is an ordinary student at Shinyo Academy, the girlfriend of Keiji Takeda and a good friend of Kazuko Suema. Unbeknownst to most, though, including herself, Touka hosts the mysterious entity known as Boogiepop inside her mind.
Touka is a young girl with shoulder-length dark brown hair and brown eyes. She is most often seen wearing the Shinyo Academy female; a white sailor uniform with a yellow cardigan over it and a short, dark blue skirt. She also often unconsciously carries around a Spalding bag, inside of which is the Boogiepop outfit.
In the anime, Touka has reddish-brown hair styled in a bob haircut, blue eyes and she wears the female Shinyo Academy school uniform, which is a white shirt with a red ribbon tied around the collar, over which she wears a yellow cardigan and blue blazer and a pale blue short skirt.
Unlike Boogiepop, Touka is an outstandingly normal person who has a cheerful and mischievous personality, and easily gets along with other people. Judging by how she paid no mind to the negative rumors about Nagi Kirima and spoke to her normally, it can be said that she is brave, and a good-natured person. She isn't very smart, having to constantly rely on Kazuko Suema's tutoring just to pass the exam. Even so, she never seems particularly worried about not passing, even occasionally saying that she wouldn't go to college, though not in a serious manner. She is hopelessly in love with Keiji Takeda, and, although he wasn't able to spend that much time with her because of his job as a designer, he also loves Touka very much. In spite of their obvious differences, Boogiepop and Touka do also share some similarities, such as their strong desire to help others and their kindness.
Touka was born to a completely normal Japanese family and her first involvement with the abnormal was during the serial killer incident, when Boogiepop first emerged from her. All her memories of this time were "corrected" to erase any evidence of Boogiepop, so she never figured out anything. However, her family situation became strained after her mother witnessed Boogiepop. However, The rest of the family didn't believe her mother and the woman began to be treated like she was insane.
