The January 2020 issue of Shueisha's Jump SQ. magazine teased on Wednesday that Ryōsuke Takeuchi and Hikaru Miyoshi's Yūkoku no Moriarty ( Moriarty the Patriot ) manga and Shō Aimoto's Kemono Jihen (Monster Incidents) manga will both have an "important announcement" in the magazine's February issue, which will ship on January 4. Both manga will be featured on the cover of the February issue.

Moriarty the Patriot debuted in August 2016. Takeuchi draws the storyboards and Miyoshi provides the art. A novel also shipped in November 2018. The manga inspired a stage musical that ran in Japan in May. A previous tease for an "important announcement" for the manga in November 2018 turned out to be for a character popularity poll.

The story's protagonist is James Moriarty, the famous antagonist from Sir Arthur Conan Doyle's Sherlock Holmes series. In the manga, he is an orphan who assumes the name William James Moriarty when he and his younger brother are adopted into the Moriarty family. As a young man, he seeks to remove the ills caused by England's strict class system.

Aimoto (Hokenshitsu no Shinigami) launched Kemono Jihen in Jump SQ. in December 2016. The manga's ninth volume shipped on November 1. The manga starts in a quiet rural village, where a strange incident occurs where many domestic animals die unnatural deaths. To resolve the incident, an odd-looking man from Tokyo who goes by the name of "Inugami" comes to the town to investigate. In the town, he meets a young boy who has a mysterious air about him called "Dorotabō."
