I am Mizuho Kazami. I'm a homeroom teacher at class 1B, in Nagano Prefectural Kizaki High School. I'm 23. I'm secretly half-alien, half-human. I came to Earth to observe and study humans. My real identity ended up being discovered by a boy called Kei Kusanagi, causing legal problems with the Galactic Federation. Because of this, I ended up marrying this boy, so I could keep living on Earth. Now Kei lives with me as my covet husband, as we also try to hide our relationship.
