Adachitoka (あだちとか) is the pen name of the creators of Noragami (ノラガミ). It is a portmanteau of the names of the character artist Adachi (
Adachitoka first submitted their work to Monthly Shounen Jump (but got rejected) and Monthly Afternoon (but received no response). They submitted three manga to Monthly Shounen Magazine, and moved to Tokyo after graduating college to begin their career as a mangaka under the pen name "Tougen-kyo". The duo then began working as an assistant to Motohiro Katou, who gave critiques of their manga and came up with their current pen name.
Adachitoka debuted by providing the illustrations for the manga "Alive: The Final Evolution" (アライブ -最終 進化的 少年-), written by Tadashi Kawashima and serialized in Monthly Shounen Magazine from 2003-2010.
After completing their work on "Alive," Adachitoka had an idea for a new series based around a "Yato-like" character from a one-shot they had previously written. This idea was developed into Noragami, which began its serialization on December 6, 2010 and is Adachitoka's first original work.
Due to health concerns, Adachitoka took a year-long break from writing Noragami from April 2017 to May 2018.
