Haruki Amemori is a gentle, feminine-looking high school boy living in a strange world where girls have never existed. Because of his soft appearance and graceful mannerisms, people sometimes mistake him for a girl at first glance, although everyone in his world knows that he is a boy.

Haruki has long, slightly wavy brown hair that reaches down past his shoulders, with a few loose strands framing his face. His large brown anime-style eyes give him a warm and innocent expression.
