Being a teenager can be hard. Himeno is a sweet, shy girl who is not perfect, but she is making the best of her situation and trying to deal with new and old feelings, just like any other high school student.

The only difference is that she is a centaur, a creature that is half horse and half human.

But she is not on her own! All of her classmates are supernatural anime characters.

Some are mermaids, others are elves, and others have horns, wings, tails, halos, or something else that makes them stand out.

Even though Himeno and her three best friends look like they are from another world, they are just like any other teenagers who are trying to figure out life and love.

They go to school every day and try to have fun while dealing with problems that most teenagers face.
