Hunter × Hunter
Written and illustrated by Yoshihiro Togashi, the "Hunter × Hunter" manga began its ongoing serialization in "Weekly Shōnen Jump" magazine on March 3, 1998. Shueisha has compiled most of the chapters into 36 "tankōbon" volumes as of October 2018. In December 2011, Shueisha began republishing the manga into a magazine-styled "sōshūhen" format. The company published one volume per month for a total of six volumes, covering up to the end of the Greed Island story arc. In December 2012, Togashi wrote a two-part manga titled to act as a prequel to the first animated film. "Tokyo Ghoul" author Sui Ishida created a 69-page storyboard of a manga chapter depicting the past of "Hunter × Hunter"s Hisoka. The storyboard was released digitally via "Shonen Jump+" on June 2, 2016.
Hayate × Blade
"Hayate × Blade" began as a manga series written and illustrated by Shizuru Hayashiya which started serialization in ASCII Media Works' shōnen manga magazine "Dengeki Daioh" on November 21, 2003 and ran in that magazine until May 21, 2008. The manga restarted serialization in Shueisha's seinen manga magazine "Ultra Jump" on August 19, 2008, and continued until July 2013. The reason for the switch was not explicitly explained, but the reason given was due to "various circumstances". Eight "tankōbon" volumes were released in Japan by ASCII Media Works under their Dengeki Comics imprint between June 26, 2004 and January 26, 2008, though Shueisha republished the eight volumes under their Young Jump Comics imprint featuring new covers, new character descriptions and revised panels. Shueisha published the remaining 10 volumes through volume 18 between December 19, 2008 and September 19, 2013. Seven Seas Entertainment licensed the manga for release in English, and the first six volumes were released between November 2008 and April 2010. As a result of the change of magazines in Japan, Seven Seas Entertainment lost the rights to continue publishing further English-language volumes of the manga series. A sequel manga, "Hayate × Blade 2", began serialization in the September 2013 issue of "Ultra Jump".
