Monthly Shōnen Ace (月刊少年エース, Gekkan Shōnen Ēsu) is a monthly shōnen manga magazine in Japan published by Kadokawa Shoten, started in 1994. Unlike the big shōnen weeklies with circulation figures in the millions, Ace is aimed at a less mainstream audience, and has a particular emphasis on anime tie-ins.
