The emotions and spirits of others flow directly into the brain.

—Two people burdened with the ability called "Sensory Abnormality (Noise)."

Partners in a fixer business taking dangerous requests in the underworld, Ritsu and Guest live their days tormented by the unpleasant emotions emitted by those around them.

Ritsu, who suffers splitting headaches from the murderous intent and hatred emitted by targets.

Guest, who suffers hyperventilation and strong rejection reactions from the sludgy, distorted desires and clingy affection of others.

For these two with opposing noises, each other was the "only safe zone where no poison exists."

The only way to save a spirit at its limit is to touch.

In the midst of a crime scene, when they deeply interlace fingers inside a coat pocket to avoid detection, a miraculous "silence" visits them.

The fading of noise transmitted through the hand, and the slight true feelings of the other flowing directly into the brain. For these two who cannot stay sane without each other, a painful yet tense "codependency for survival" begins.
