Kitty is a Japanese bobtail cat who plunges into a parallel dimension through a hole alongside her twin sister, Mimmy. This world mirrors their own but is inhabited by humanoid beings with transparent wings and pointed ears.

In this strange realm, Kitty allies with Emily, a resident supermodel. Their urgent mission is to locate and rescue Mimmy, who vanished shortly after their arrival. Akuro, a black cat antagonist serving the evil wizard Makkuro, consistently sabotages Kitty's search efforts.

Guidance comes from Pururuu, a forest fairy connected to the mystical apple woodlands, whose support proves crucial as Kitty navigates the parallel world's challenges. The core narrative focuses on Kitty's persistent efforts to overcome obstacles created by Akuro and Makkuro to reunite with Mimmy.

A significant revelation exposes Akuro as Mimmy, magically manipulated and transformed by Makkuro. This confirms Mimmy was controlled into opposing Kitty throughout the journey. Kitty's role remains centered on confronting these adversarial forces to restore her sister to safety.
