Takahashi Tetsuo is a demi-obsessed researcher who wants to learn more about the demi-humans, aka demis, living in the world. When he starts a new teaching job, he discovers four demis at the school and does the only thing a researcher can do - interview them! But he's about to learn there's more to these girls than the legends claim. Nothing's more complicated than being a teenaged demi.
