Miki Yoshikawa made her pro manga debut in 2003 with Glory Days, a one-shot in Kodansha’s Magazine Special. After a stint as an assistant for Hiro Mashima (Fairy Tail), she published another one-shot, Yankee-kun to Megane-chan, in Shonen Magazine Wonder in 2005. Yoshikawa’s best known work, Yamada-kun and the Seven Witches, started serialization in 2012 and has since sold more than 3 million copies.
In 2015, Yoshikawa attended Anime Expo as a guest.
At Anime Expo 2015, Yoshikawa said that she was inspired by the Dragon Ball manga, and would try to copy some of Toriyama's panels and manuscripts. She credits Hiro Mashima for "teaching her everything I know" while she was assisting on Fairy Tail.
