History

Klein was associated with the Night Watchers during Old Neil’s loss-of-control incident. He was concerned for Neil’s survival and accepted that his mysticism lessons had to be suspended because further contact with mystical knowledge posed a danger. 27

He became the host of the Tarot Club under the identity of Mr. Fool, using the Gray Fog to gather members, translate diary pages, answer requests, and regulate exchanges. His position requires him to preserve an image of unknowable authority despite frequent anxiety that members—especially Mr. Devil—may uncover his true identity. 176 206

After faking his death, Klein reunited with Benson and Melissa in Backlund while concealing the nature of his new life. He arranged for their housing and financial security through a shareholding worth one thousand pounds, though Benson immediately questioned how Klein had gained access to such resources. 226 242

As a Faceless, Klein expanded his network of identities. He operated as detective Sherlock Moriarty, the adventurer Gehrman Sparrow, and later Kidd Robin, an identity shared among several of the Fool’s followers. 146 374 477

Klein’s exploration of Sno’s ancient-castle trial led him to the Zi Wei pocket watch, evidence of Senior Perrdax’s existence, and a sleeping figure resembling Mr. Devil. These discoveries were deliberately arranged to deepen Klein’s belief in the transmigrated senior, completing Sno’s ritual for his own advancement. 406 408

During the final struggle surrounding the Lord of the Mysteries’ revival, Klein rejected Feng Xue’s offer to return to the past. With Feng Xue and the Night Goddess, he used a crucifix containing pillar-level auras to contaminate and disrupt the awakening consciousness within himself. 607 608

Personality

Klein is cautious, methodical, and accustomed to preparing contingencies. He repeatedly uses divination before acting, carefully evaluates risks, and distrusts apparent coincidences after his experiences with 0-08 and other fate-manipulating powers. 147 160 522

He is deeply attached to Benson and Melissa. His desire to protect them repeatedly motivates his advancement, even while he fears exposing them to the dangers surrounding his resurrection and Beyonder life. 104 224 226

Despite the distant persona of Mr. Fool, Klein is easily embarrassed by his disguises, theatrical equipment, and Mr. Devil’s provocations. His Clown abilities often let him conceal reactions that would otherwise expose his discomfort. 157 310 411 537

He is curious about transmigrators, Emperor Roselle, Senior Perrdax, and the Western Continent, but recognizes that some knowledge carries the risk of corruption. 294 460 508 533
