Houkago Hokenshitsu, IS: Otoko demo Onna demo Nai Sei Recommendations
If you read one or the other you can see why I recommended it. They are both similar in certain aspects, situations, and more. Trust me.
Both stories are thought-provoking and beautiful, they challenge standard notions of set gender roles and more.
Both series feature Intersexuals as protagonists. I.S. is a heartwarming, true-to-life story and exposé about the lives of Intersexuals. After School Nightmare is less sensitive about Intersex issues, and uses it more of a plot device, albeit a brilliant one. Both series feature Intersex protagonists who struggle with their gender identity and romance, and both are worth the read.
