These girls aren't human. Still, they adore humans more than anyone. I am Hitoma Rei, a NEET nearing 30 years old who was traumatized by human relationships. When I changed jobs, I ended up at an all-girls school whose purpose is to take non-humans and make them human!? Spending my days with the strange students Minadzuki Kyouka, a mermaid; Oogami Isaki, a warewolf; Usami Sui, a rabbit; and Haneda Tobari, a bird... Why do they want to be human? What do they want to do once they become human? I will teach them about humans. This may be an alternate world, but it's not like I've been reincarnated. This is just the story of a teacher who spends time with some girls who wish to become human, in a slightly odd school.
