(Insignificant Kawaraya!!), which she had been working on privately since 2011 before turning it into a commercial manga in 2015. Eno then went on to create Ajuutan (Tale of the Demi-Beast), which was among the top twenty series nominated for the Next Manga Award's Best Web Manga of 2017. And in 2023, Eno received her second Next Manga Award nomination for the work on her series After God.
