One (manga artist)

One was born in Niigata and grew up in Saitama. While visiting his grandparents in Niigata, his parents bought him a series of manga called Crayon Shin-chan by Yoshito Usui.^[5] One was a fan of the manga, which influenced his decision to become a manga artist, and began practicing on his notebook during middle and high school.^[6]

In July 2009, One began publishing a short version of One-Punch Man on Shintosha, a comic-posting website. He later began irregularly uploading One-Punch Man to his web page FC2 on July 3, 2009.^[7] Originally, One-Punch Man was intended to be a one-off to further practice drawing, but became a series following positive reception.^[6] Due to its humorous setting and story, One-Punch Man became popular in Japan.^[7] One had a special interest in creating a protagonist that had already become the strongest in the world,^[8][9] which enabled him to concentrate on a different perspective of the background and storytelling. One stated that he envisioned the protagonist, Saitama, as a character capable of adapting to the world that surrounded him, with his primary obstacles being mundane things.^[8] Before One decided to become a full-time manga artist, he had taken several hiatuses from updating the webcomic, including a one-year hiatus in February 2010 to work at a full-time job,^[6] and a two-year hiatus after releasing the 109th chapter in January 2017.^[1]

Manga artist Yusuke Murata was interested in One's work and eventually reached out to One.^[10] The two would collaborate in publishing two one-shots in 2012; Dotō no Yūshatachi, which released on April 1 in Weekly Young Jump, and Dangan Tenshi Fan Club, which released on April 17 in Miracle Jump.^[11][12] A remake of One-Punch Man began serialization in Shueisha's Tonari no Young Jump website on June 14, 2012.^[13][9][14] One-Punch Man would also receive an anime adaptation, announced in the 15th issue of Weekly Young Jump on March 10, 2015.^[15] The first season aired in Japan from October 5 to December 21, 2015,^[16] with live-action film adaptation also in development.^[17] The same year, One wrote and illustrated Mob Psycho 100, which began serialization in Shogakukan's Ura Sunday webcomic magazine on April 18, 2012.^[18] The protagonist, Shigeo Kageyama, is meant to come off as "somewhat standoffish or nerdy," while also possessing heroic traits.^[19] The series finished on December 22, 2017.^[20] On November 26, 2022, Versus began serialization in Kodansha's Shonen Sirius magazine, written by One and illustrated by Kyōtarō Azuma.^[21]
