Q Hayashida (林田球, Hayashida Kyu) is a manga author from Tokyo. Hayashida studied oil painting at Tokyo University of the Arts. She has discussed her childhood and artistic inspirations in interviews but maintains a high level of privacy about her personal life, to the point that her true name and face are unknown. Hayashida's first major manga was Maken X Another (1999-2001), a comic book adaptation of a video game. Her most famous work is the 23-volumes long Dorohedoro (2000-2018). It was originally serialised in the alternative manga magazine 'Monthly Ikki', but it was later moved to 'Hibana' when Ikki ceased publication, and finally transferred to 'Monthly Shōnen Sunday'. Dorohedoro has been partially adapted into an anime on Netflix in 2018. Hayashida's most recent manga series Dai Dark began serialisation in 2019 in the pages of Monthly Shōnen Sunday.
