Hana Itoki (糸奇はな; born September 15, 1991) is a Japanese singer-songwriter, composer, illustrator, and designer. She graduated from the vocal music department of Kyoto City University of Arts. During elementary school, she lived in Switzerland, and a performance of The Phantom of the Opera in London inspired her to study vocal music.
In 2011, she began releasing arrangements and original songs on video-sharing sites, developing her music alongside visual expression. She self-released the CD "体内時計" through online sales in 2016. In 2017, she sang "Wa -cycle- (環-cycle-)," the first ending theme for "Mahoutsukai no Yome", and the song marked her major debut.
She released her first full album, "PRAY", in 2018, followed by her second, "VOID", in 2020. Alongside her singing and composition, she has also continued to work as an illustrator and designer, carrying that work across both her music and visual output.
