Sega Hard Girls (セガ・ハード・ガールズ) is a Japanese multimedia project produced as a collaboration between ASCII Media Works' Dengeki Bunko imprint and video game company Sega. The project re-imagines various Sega video game consoles as anthropomorphized girls in modern Japan.
The project has inspired a light novel series written by Tōru Shiwasu with illustrations by Kei Garō, which was serialized in ASCII Media Works' Dengeki Bunko Magazine between 2013 and 2014, and an anime television series adaptation titled Hi-sCoool! SeHa Girls (Hi☆sCoool! セハガール) by TMS Entertainment, which aired in Japan between October and December 2014. A crossover video game with Idea Factory's Hyperdimension Neptunia franchise, Superdimension Neptune VS Sega Hard Girls, was released for the PlayStation Vita in Japan in November 2015, and in North America and Europe in October 2016.
Premise
The project focuses on various anthropomorphized Sega consoles, known as "Sega Hard Girls" or "SeHa Girls" for short, each with their own unique personality. The anime series follows three such girls; Dreamcast, Sega Saturn, and Mega Drive, who must graduate from Sehagaga Academy, a special school located in Haneda, Tokyo (the real-life location of Sega's corporate offices), by venturing into the worlds of various Sega games and earning medals. The light novels instead depict the girls as goddesses who come to live with the book's protagonist, high school student Isao Sugawara, and purify other goddesses who have been cursed to become vengeful spirits.
