Publication
Written and illustrated by Kaito Mitsuhashi, Ryoko was preceded by a work titled Ryoko Meet Meal!!, for which Mitsuhashi, at 21, won the Shin Shedai Sunday Award (New Generation Sunday Award) for his work in December 2015.[2][3] Takenori Ichihara, then Shogakukan's Weekly Shōnen Sunday editor-in-chief, decided to make Ryoko a serialized work, making it the first time in 38 years that an editor-in-chief directly chooses a newcomer's work to be serialized in the magazine, since Rumiko Takahashi's Kattena Yatsura (Urusei Yatsura prototype) in 1978. It was also the first time that a newcomer award-winning work would be serialized in Weekly Shōnen Sunday, since Obi wo Gyutto Ne! [ja] by Katsutoshi Kawai [ja] (1989 debut) and Ushio & Tora by Kazuhiro Fujita (1990 debut).[2][4]
The manga began in Weekly Shōnen Sunday on October 19, 2016.[4][2] The manga went on hiatus after its 22nd chapter, published on March 29, 2017.[5] The series resumed publication on January 23, 2019,[6][7] and finished on June 26 of the same year.[8] Shogakukan collected its chapters in five tankōbon volumes, released from February 17, 2017, to September 18, 2019.[9][10]
