Born in Hokkaido on October 23, she began her career in 1999 as a Houshin Engi doujinshi artist as well as doing fanart from popular series like Hikaru no Go, Shaman King and Yami no Matsuei.
Finally she got her break when her first original series, Harlem Beat wa Yoake Made was serialized in Kadokawa's Monthly Asuka.
The lawsuit was founded on Takashima's belief that Kayono had directly traced over her work Wild Rock, and used it for her own manga.
Takashima was more active on her blog in 2011,[3] and in her December 10 entry, stated that she "took a break" that she felt was necessary and that she "plans to work hard" in the new year.
[7] Among the early posts on here, she lists, in great detail, all of her various works, including published manga, illustration contributions, and minor things like doujinshi, pinups, advertisements, one-shot stories, etc.
In June 2019, she made a post to her blog advertising the latest chapter of Whiskers and Tails, and mentioned that she'd been considering continuing one of her old works.
