A former elite police officer, traumatized by his exceptional abilities and excessive empathy, quits and opens a small detective agency, making a living from minor cases like finding missing people and lost cats. His personality grows somewhat jaded and distant, but his sense of justice and curiosity remain alive deep down. After being reborn, he possesses memories of the next month and the ability called "Chaotic Whispers." His goals are to stop a series of disappearances, find the person who killed him, and uncover the System's origins and purpose. He must stay clear-headed amid constant mental torment and make use of this terrifying ability. He goes from being forced to endure his powers and wanting only to settle personal scores, to gradually learning to find patterns in the noise, control his abilities, and understand the deeper meaning, or conspiracy, behind them. He must learn to trust others again, rather than relying solely on mind-reading, and find a balance between saving others and protecting himself.
