The title has three stated meanings: public square ("a plaza where comic lovers and talented artists and writers come together"), algebraic square ("Weekly Shōnen Jump"²), and "SQ = Supreme Quality" (referring to its "Supreme Quality Manga Magazine" motto). Four manga serials were temporarily moved to "Weekly Shōnen Jump", until Jump Square's release. These four series, "Tegami Bachi", "Rosario + Vampire", "Claymore", and "Gag Manga Biyori" were among the magazine's premiere series, along with debuting series, including "Embalming -The Another Tale of Frankenstein-", "Kure-nai", and "". Circulation. When "Jump Square" was launched, the initial printing of 500,000 copies quickly  sold out. Over 70% of the copies released across Japan sold within three days. Shueisha printed an additional 100,000 copies to help meet the demand, something normally not necessary with Japanese magazines. The second issue also sold well, requiring a second printing of 60,000 copies. After the first issue excitement died down, circulation leveled off in the vicinity of 370,000 copies and by 2015 had declined to 270,000, mirroring a general drop-off in circulation throughout the industry.
