As of my last update in April 2023, Sarasa Nagase is a Japanese author known for her work in the light novel genre. She is best recognized for writing "I'm in Love with the Villainess," which is a yuri light novel series with an original story that stands out in the isekai (another world) theme, focusing on a female protagonist who falls in love with another woman. Nagase's work has gained popularity both in Japan and internationally, particularly within the LGBTQ+ community for its progressive and inclusive storytelling. Not much personal detail may be available as many light novel authors in Japan maintain a private profile.
