The first 2019 issue of Shogakukan’s Weekly Shonen Sunday magazine has announced Kotoyama will publish a new one-shot manga titled “Itookashi” in the magazine’s combined fourth and fifth issue on December 26, 2018.
The announcement shows a character that appears similar to the character Hajime Owari from Kotoyama’s Dagashi Kashi manga, and teases, “Dagashi Kashi’s Kotoyama returns with a one-shot!! […] Eight months after the Dagashi Kashi finale … an anticipated one-shot is published! The main lead is … ‘her’!?”
Kotoyama began the Dagashi Kashi manga in Weekly Shonen Sunday magazine in June 2014, and ended it on April 11, 2018.
