宇宙 仁

Sora Hitoshi is the space alien responsible for transforming Hazumu from male to female. He arrived to Earth via his spaceship run by an artificial intelligence named Jan Pu, but crash lands on the surface  where Hazumu is, killing him instantly. Hitoshi rectifies this by regenerating Hazumu, but unexpectedly changes his physical sex in the process. This is a mystery to Hitoshi for some time until he is finally able to confirm that Hazumu's "life grain" count is slowly dissipating, and by the time Hitoshi confirms this, Hazumu only has one month left to live/.
Hitoshi originally came to Earth as a cultural anthropologist and to study the emotions of the human race since his species has long-since given up any emotion at all. He arrives at the conclusion that his species needs to remember how to love each other in order to survive, so love becomes a focus of his research. In order to observe humans more closely, along with Hazumu and her ongoing relationship with Yasuna and Tomari, Hitoshi starts working at Hazumu's school as a biology teacher, and inadvertently becomes the target of Namiko's extreme affections.
