Suzunari!, Vol. 1

Kaede Takamura's teenage life swerves to the brink of insanity when she
comes face to face with her twin...or does she? Suzu is practically the
mirror-image of Kaede - except for having cat ears and a tail and being
far more well-endowed than Kaede thinks any teenager ought to be. But
the Takamuras have no qualms about bringing this strange,
happy-go-lucky catgirl into their home. With Suzu completely ignorant
of the ways of modern society, it's going to be a very long year for
poor Kaede.
