Oshioshio

Oshioshio is a native of Kanagawa Prefecture. After graduating from art school, she worked for an advertising company, but left after about a year to pursue a career in illustration. While working on doujinshi activities, she was invited by an editor at Houbunsha to make her debut as a commercial manga artist with Kamisama to Quintet, a yonkoma manga depicting the campus life of art school students. She also began serializing another manga, Sakura Maimai, in Comic Cune. Through her editor at Comic Cune, Oshioshio was approached by an editor at MF Bunko J for her first light novel illustration: Noboru Okazaki's Hime-sama, Sekai Horobu kara Gohan Tabete Ikimasuyo!. Oshioshio, who had long admired light novel illustrator Kouhaku Kuroboshi, subsequently made her light novel illustration debut with the first volume in 2016. She is the character designer for Hololive Production VTuber Amane Kanata and Nijisanji VTuber Soraboshi Kirame. Real Sound said that both character designs "are short and small-chested; these two points seem to be non-negotiable for Oshio, and even when the two of them later asked her to make them taller "make her bust bigger" or "make her taller," she refused every time". In 2021, she exhibited at the 10th edition of Sankei Shimbun's Eshi100 exhibition. In September 2022, her first solo exhibition, Blue light, was held at Pixiv Waen Gallery. In February 2023, Ichijinsha released an art book on her work, Oshioshio Gashū: Ao no Hibi. She later began serializing the comedy manga My Deer Friend Nokotan in Shōnen Magazine Edge. In 2024, she also assisted in the production of the manga's anime adaptation, including with casting and adding anime-only content. Among her themes are illustrations of sad, crying girls, as well as "conveying the emotions of characters, focusing on illustrations of fragile and delicate girls".
