[7] Nakatani's first complete project was produced around the time of her high school graduation, after which she continued drawing until her art met a professional standard.

[6] Nakatani became known as a manga artist through her work on doujinshi, especially those based on the Touhou Project series,[8] which she published under the pseudonym "Rireba" (リレバ).

[12][13] Farewell to My Alter appeared in the magazine in October 2014 as Nakatani's professional debut, winning her a Gold award in the 21st Dengeki Comics Grand Prize contest.

[14][15][8] Nakatani created one additional one-shot work for the magazine, Tear-Flavored Escargot, which appeared in the December 2014 issue prior to her first serialization.

[13] Because her works were primarily about relationships between girls (a fact which Nakatani attributed to the Touhou series' almost entirely female cast), she gained a reputation as an author of yuri manga.

[8][28] Nakatani's current work, Kami-sama ga Machigaeru, was announced in Dengeki Daioh on September 26, 2021, and began serialization on October 27, 2021.
