Kirigaya Touko

Kirigaya Touko is a second-year student at Tsukinomori Girls' Academy, and the guitarist of Morfonica. She handles the band's costumes and like Lisa, follows.

Outside of the band she is friends with Sayo and Kaoru. She is also classmates with both Mashiro and Rui, and is also the class president.

Background
Touko's family owns a classic and famous kimono shop; as a result, she is knowledgeable of making outfits and loves fashion. She also has her own fashion brand "TOKO", which mostly sells T-shirts. She lives together with her grandmother and parents. Her grandmother is a great cook, but according to Touko she is also very strict, doesn't let Touko practice at home, only cooks traditional Japanese food and constantly tries to push Touko to attend tea ceremonies and other kinds of fancy events.

She and Tsukushi attended Tsukinomori's elementary and middle school together. However, they had never talked to each other, and when they first meet at CiRCLE, Touko mistakenly calls her "Tanaka-san" and "Yamada" (two very common Japanese surnames).

Appearance
Touko has long, wavy blonde hair and light-brown eyes. Her bangs part to her left and stop just at the eye.

Personality
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. She is quite confident in herself and the ideas she comes up with, and has sworn that one day she'll become so popular they'll erect a bronze statue of her in Tsukinomori's courtyard.

She sometimes argues with Rui as well due to their clashing and contrasting personalities. This is especially shown in the An Étude to Spread Our Wings event, in which Touko and Rui have an argument due to Rui refusing to give Touko the highlight part in their new song due to her lackluster talent in guitar. This pushes Touko to become more determined and practice more often, causing her to seek out Sayo, Kaoru and Tae to teach her how to play the guitar properly, wanting to be acknowledged by Rui.
