Jump Square (ジャンプスクエア Janpu Sukuea, written as Jump SQ
 but pronounced "Jump Square") is a Japanese monthly shōnen manga 
magazine with a circulation of over 300,000. Published by Shueisha, the 
magazine premiered on November 2, 2007 as a replacement for Monthly 
Shōnen Jump, another manga anthology that Shueisha discontinued in June 
of that year. The magazine is a part of the Jump line of magazines. The 
manga titles serialized in the magazine are also published in tankōbon 
volumes under the Jump Comics label. The manga series within the 
magazine target young male readers and tend to be set in a fantasy 
setting with a large amount of action scenes. Like all monthly shonen 
manga magazines, Monthly Jump Square is aimed at late teens and people 
in their early 20s from ages 16 to 21.
