Summary
Shinobu Sensui, a twenty-six-year-old with a birthday on June 6th and blood type A, served as Earth's Spirit Detective prior to Yusuke Urameshi. Koenma identified him as the natural successor, citing his exceptional spirit awareness, formidable strength, and a rigid moral compass. Sensui adhered strictly to a black-and-white worldview: humans were innocent victims requiring protection, while demons were inherently evil and destined for death. This perspective shifted slightly when he encountered Itsuki, a demon who requested a reprieve to watch the finale of his favorite TV show. Struck by this display of humanity, Sensui laughed and spared him, leading him to realize that not all demons were malicious. Nevertheless, his unwavering stance toward humanity remained unshaken until a pivotal night changed everything.
