Mitsue Aoki is a Japanese manga artist born on February 24, 1969, in Amagasaki, Hyogo Prefecture. She graduated from the design department of Seiwa College. Her career began in 1988 with her debut story Chuka, which was published in the photography magazine Pink House.

Aoki is best known as the creator of the manga series Koume-chan ga Iku! (小梅ちゃんが行く!!, also known as Here Comes Koume!!). The series, a comedy about a new office lady from Osaka working at a design firm, was serialized from 1993 to 1996. It became her most prominent work when it was adapted into a 12-episode anime television series in 1999. The anime was a co-production involving the studios Gainax and Group TAC, with Mitsue Aoki credited as the original creator. She later wrote a sequel, Koume-chan Ga Iku! R, which was published from 2000 to 2001.

Throughout her career, Aoki has worked across a variety of formats, including short gag manga, story manga, four-panel yonkoma, and essays. Her body of work is extensive and has been published by several major Japanese publishers such as Takeshobo, Shueisha, and Shodensha. Notable works include the series Neko Nekotai ga Iku!!, serialized in Ultra Jump from 2002 to 2004, and Sweet delicious, which ran from 2001 to 2004. Her series Tonari no Shibafu wa and its sequel were published by Shueisha in 1997 and 2000, respectively.

Her artistic identity is characterized by a focus on drawing cute girls and crafting stories with a cheerful atmosphere, often based on personal experiences. She has written in various genres, including comedy, slice of life, and josei (manga aimed at adult women), though her work spans several demographics. In the industry, she is recognized for her consistent output since the early 1990s and for having one of her manga series adapted into an anime by notable studios, solidifying her status as an established creator in the manga and anime landscape.
