Touko is a popular girl who gathers people around her both at school and on social media, where she goes by the name TOKO and is known as a popular influencer who's able to find and create the latest trends. She is a cheerful and open-hearted girl, but those around her are often caught up by her tendency to play things by ear. She often talks in gyaru slang, especially using the words "yabai", "maji" and "mikuron" (no biggie), and wants to take selfies no matter where she goes (even during performances). She loves to tease Tsukushi, which at times leads them to arguing.
