This year's January issue of Shonengahosha's Young King Ours magazine announced after the final chapter of Satoshi Mizukami's Nihonmatsu Kyōdai to Mokuzō Keikoku no Bōken manga on Thursday that a new "large-scale" science fiction series will begin in the magazine's April issue.
Mizukami launched Nihonmatsu Kyōdai to Mokuzō Keikoku no Bōken (Adventure of Wooden Valley or lit: The Nihonmatsu Siblings and the Adventure of Wooden Valley), pictured right, on June 30. The compiled volume will ship on January 10. The note after the final chapter also teases it as the end of the siblings' "first adventure."
Mizukami drew and wrote the Lucifer and the Biscuit Hammer manga, which launched in Young King Ours magazine in April 2005, and ended in 2010. JManga once carried the manga, and Seven Seas Entertainment later licensed and released the manga in print in North America. Crunchyroll also published the manga digitally.
Mizukami launched his Spirit Circle manga in Young King Ours in May 2012, and ended the series in March 2016. Shonengahosha shipped the sixth and final compiled volume in June 2016. Crunchyroll began simultaneous publication of the manga in 2014, and Seven Seas Entertainment released the manga's first volume in print on October 10.
