50on! is the doujin circle of Aiue Oka (愛上陸), a joint pen name under which two artists, Echizen and waon, work as one. Commercially, Aiue Oka has drawn for COMIC X-EROS and published the collections Yumemiru Otome and Ijirare with Wanimagazine. In doujin, the circle's FANZA releases began in 2015 with Boku no Aishita Kanmusu, a derivative of Kantai Collection. From 2017 it published Saimin Seishidō, a school-set hypnosis series, in print and digital, shifting its focus to a different character with each chapter in the manner of an ensemble piece; most of the single chapters came out as FANZA exclusives. The print editions took first place in Toranoana's annual doujinshi ranking in both 2019 and 2020, and with Saimin Seishidō Sōshūhen, distributed at Comic Market 97 in winter 2019, the series appeared on DLsite for the first time. It has since expanded into a six-episode OVA, novelizations and a 2024 PC game, and a new installment came out on FANZA in 2026.
