Person: Shinjou Mayu

Shinjou Mayu, born January 26, 1973 is a Japanese manga artist. She debuted in 1994 in Shogakukan's Shoujo Comic with Anata no Iro ni Somaritai. She continued writing for Shogakukan until 2007, with her works appearing in both Shoujo Comic and their other magazine Cheese!. She left the company to go freelance citing a dispute over working conditions and abusive treatment by her editor.

Shinjou made her debut at publisher Shogakukan in 1994, drawing series for Shoujo Comic magazine. In 2007 she left the company, noting that her editors were excessively demanding and abusive, creating a stressful work environment.

In her blog, Shinjou noted that though she was the actual creator of her manga titles, she was one of the last to know about any adaptation plans for her series, even learning about some through TV channel websites instead of her editor. When she decided to leave, one editor threatened to take all of her earlier series out of print, but Shinjou contacted a lawyer and the threat was never carried out.
