Background

Ke Qirui was a highly watched rising star in China's Exorcist Association, possessing an SS-Rank Heavenly Drive alongside Xia Pingzhou. She knew Xia Pingzhou from the Association before he left it under unclear circumstances. 39 40

She became Su Zimai's teacher in the Exorcist field and later led her as a member of the Ghost Train Troupe. Although she initially found Gu Wenyu unusually suspicious after meeting him, her deductions repeatedly brought her close to uncovering the hidden identities around Su Zimai. 26 27 64 73

Appearance

Ke Qirui is a mixed-race young woman with a composed, refined appearance and a distinctive detective-like style. 38 59

• Usually wears a khaki trench coat, leather boots, and a Lüsterk hat. 38 59
• Wears an old-fashioned monocle over her left eye, attached to her collar by a chain. 59
• Frequently carries a pipe or cigarette holder and smokes while thinking. 59 60

Personality

Ke Qirui is observant, analytical, and willing to act on incomplete information. She distinguishes between different supernatural systems, deduces hidden identities from behavioral evidence, and accurately pieced together that Su Zimai's brother was likely an Esper rather than an Exorcist or Anecdote Envoy. 63 64

Despite her calm manners, she can be forceful when necessary. When Xia Pingzhou attempted to avoid her at Roppongi EX Theater, she made clear that she could make him stay for a conversation. 60 She also has a dry sense of humor, joking that the Train Demon's reputation has become greater than her own. 95

Her protectiveness is most apparent around Su Zimai. She equipped Su for a dangerous investigation, concealed her location from Gu Qiye until confronted, and promised to keep her safe. 65 107 113

Story Role

Tokyo Underworld Auction

During the crisis, she coordinated with her teammates, deduced Haihara Ritsu's role as the White Crow Troupe Leader, and used the Train Demon's battlefield-control capabilities to delay stronger opponents rather than attempt a direct victory. 95 116 120 123

Red Light Investigation

Ke Qirui led the Ghost Train Troupe toward London to capture Red Light, coordinating with Black Cocoon despite their guarded relationship.

Ke Qirui and Black Cocoon later killed Red Light to prevent information from leaking. Black Cocoon subsequently warned her to remain close to Lake Hunt because of the threat posed by Sodalitas Salvifica's infiltration. 195
