Originally from Chiba, Tsukasa Fushimi entered the first volume of Jūsanbanme no Alice into the 12th Dengeki Novel Prize in 2005. While the work did not win a prize, it survived through the third selection process and was ultimately published by ASCII Media Works under their Dengeki Bunko imprint in 2006 as Fushimi's debut work. Following the end of Jūsanbanme no Alice with volume four in 2007, Fushimi began writing the first novel of Oreimo, published in 2008. Fushimi would go on to write 12 volumes in total of Oreimo, ending in 2013. Over the course of the series, Oreimo spawned a media franchise encompassing multiple manga, anime and video game adaptations. Fushimi began his next novel series Eromanga Sensei in 2013.
