The manga series was written by Satoru Akahori and illustrated by Yukimaru Katsura.[1] Its original character designs were designed by Sukune Inugami and the school uniforms by Cospa.[1] The story focuses on Hazumu Osaragi, a normal, albeit effeminate, high-school boy who is killed when an alien spaceship crash-lands on him and is revived as a girl. As Hazumu adjusts to her new life, she enters a same-sex love triangle with her two best female friends.
