Following a decade of rigorous training, two young shape-shifting dog ninja are finally deemed ready for their first field assignment. Their mission leads them to Mitsuyoshi, an unsuspecting young man who welcomes the pair into his home under the impression that they are merely lost pets. He affectionately names them Hanzou and Hadzuki, completely unaware of the supernatural reality hiding behind their canine appearances. The duo's primary directive is to protect him from demonic threats while ensuring he never discovers their true identities. However, maintaining this deception proves far more complicated than anticipated. Before officially becoming his pets, Hadzuki had already encountered Mitsuyoshi in her human form, intervening to rescue him from a demon attack. Now forced to navigate both lives, she must keep her roles as his loyal dog and his mysterious human savior strictly separate. This delicate balancing act grows increasingly difficult as relentless demons continue to target him, forcing the ninja into action. To further complicate matters, Hadzuki finds herself developing genuine romantic feelings for the very person she has sworn to protect, blurring the line between duty and desire.
