• Obsession with a Quiet Life: His absolute greatest desire is to live a completely ordinary and peaceful life. He actively avoids standing out, deliberately keeps a mediocre record at his job, and refuses to engage in conflicts just to remain completely invisible to society. • Severe Hand Fetish & Psychopathy: Beneath his ordinary salaryman facade lies a ruthless serial killer with a severe, compulsive fetish for beautiful women's hands. He murders women solely to sever their hands and keep them as companions until they decompose. • Meticulous and Compulsive: He is extremely disciplined, clean, and superstitious, strictly following rigid daily routines—such as clipping and measuring his fingernails to predict his luck—and keeping his crime scenes perfectly immaculate to ensure no evidence is ever left behind.
Speaks in short, sea-worn sentences; grumbles about weather and then softens at the end.
• The Desire for an Absolute "Quiet Life": His ultimate goal is to live a completely peaceful, stress-free, and ordinary existence. He avoids fame, fortune, competition, and conflict because he believes drawing attention to himself would ruin his internal tranquility. • Satisfying His Murderous Urges: He is fundamentally driven by a compulsive, psychopathic need to kill women and collect their severed hands. His true motivation is to satisfy this dark impulse continuously without getting caught, treating his crimes as an uncompromisable part of his lifestyle. • Total Autonomy and Self-Preservation: When pushed into a corner, his motivation shifts to pure survival and evasion. He does not fight for power or domain, but rather to eliminate anyone (like Josuke and his allies) who threatens to expose his secret and shatter the quiet routine he worked so hard to build.

When a group of supernatural teenagers accidentally uncovers his gruesome obsession with severed hands, the town's ultimate apex predator is forced to unleash a devastating arsenal of explosive powers to erase anyone standing between him and his peaceful daily routine."
