Tokiya Ichinose (一ノ瀬 トキヤ, Ichinose Tokiya) is a student of Saotome Gakuen, initially sorted into S Class, but was later downgraded into A Class in the anime. He is also a member of the idol group ST☆RISH. He is voiced by Mamoru Miyano (宮野 真守, Miyano Mamoru).
He has midnight dark-blue hair and depending on the lighting, it almost appears black. It is parted to the right, usually with a lock reaching his nose and the end of his hair reaching to the top of his ears. The back of his hair covers his neck. He has turquoise-blue eyes that almost match his hair color. He tends to wear his uniform primly and neatly, showing his perfectionist attitude. Later on in the series he is seen to have a casual look while still dressing according to his perfectionist attitude.
Tokiya is a very cool person and considered a perfectionist. Ryuya Hyuga comments that his singing doesn't have 'heart', which makes him frustrated as his singing doesn't seem to improve in the least.
He seems cold at the beginning of the series, which may be because he felt guilty about what he was hiding. He was slightly upset, that his acting wasn't enough to help Masato Hijirikawa overcome his embracing problem in season two, since he was considered to be better at it, than his companions.
As the season's progress, it is clear that Tokiya's cold personality at the beginning of the series is not his true self. After many trials and obstacles he develops a sweeter side, as shown in Episode 11 of season two, he takes Haruka Nanami to a festival to lift her mood as she is struggling with writing a song.
In season three, it is seen that he has one of the biggest growths of all characters in the series. Along with Masato Hijirikawa, they embark on trying to write lyrics to their own music, seeing this struggle they needed moral support from the rest of their band and did overcome, Tokiya's personality grows and he is seen as a more gentle character than he was in season one. Tokiya is a perfectionist, he likes order and neatness, Tokiya has a strict diet and doesn't like to eat fatty foods. He's a very reserved individual and when it comes to work, very serious.
Despite his cool and perfectionist personality, Tokiya strongly cares about the rest of the ST☆RISH members.
His parents are divorced, his father and his mother left him because of Tokiya's ambition to become an idol.
He struggled to become an idol. After a short period of time, his agent began to push him to do other things instead of singing, which bruised his pride and took him away from his passion. He lived a double life as Hayato, his "twin brother", in an attempt to "have a normal life". He was not very close with his family, he did not spend many holidays with them due to the busy work they had to do and he grew up lonesome especially on Christmas Day.
