Tamade Chiyu is a returnee who attends Celosia Girls' Academy, which is an international school. She is 14 years old but due to her excellent grades, she is currently a 10th grader (first year high school student).

She goes by the moniker CHU² (read as CHUCHU) and is the leader, producer and DJ for the band RAISE A SUILEN. She uses DTM (Desktop Music) to compose music.

Similarly to Kokoro she is very rich and lives in a penthouse, where the band also practices at.


Ever since she was young, Chiyu has been playing music and different kinds of instruments such as the piano and violin. However, she did not start playing out of her own will, but rather because of her parents' - particularly her mother Miu's, who is a famous violinist working outseas - high expectations of her. Despite her inadequate skills, and the pressure her mother put on her, she was always complimenting Chiyu and doing what she thought was the best for her only daughter.

As a result this led to Chiyu wanting to put together the ultimate band all by herself, as she believes that by doing everything else herself, it would force people to recognize her talent.


Chiyu is a girl of average height. She has sharp sky blue eyes with curly, burnt orange hair reaching her hips, and a tall single ahoge.

She is normally seen wearing her school uniform, which consists of a white buttoned shirt with a red and white striped tie, a dark blue school blazer with long sleeves, plaid miniskirt and shin-high black socks and brown leather shoes. She also wears cat-eared headphones.


Chiyu is very professional, confident and stubborn of her band and ideas, and likes calling herself a "kind, generous producer". She tends to be quite arrogant and aggressive towards the other bands, as well as her own band members at times, however she's not rude.[1] As a result of her studying in an international school, she often speaks English or adds English words to her sentences.

Chiyu dreams of changing the world with the strongest music, and sees Yukina as her rival; however, Yukina doesn't share this sentiment. As a result she wants to crush Roselia and prove that her band is better than them; later she adds Poppin'Party to this list as well.


  • She scouted all of RAISE A SUILEN's members by herself.
  • Her birthday is the same date as when RAISE A SUILEN's 3rd official live, Brave New World, was held.
