Background / History

Klein lives in Tingen with his siblings and initially appears as a scholarly young man preparing lamb and pea stew at home. After sensing scarlet light, he performs a ritual that transports him Above the Gray Fog, where he examines the crimson stars connected to the Tarot Club he had established that day. One star lets him witness Morien drinking a potion and confronting the eyelashless eyes associated with the Hidden Sage 9.

While working through the Divination Club, Klein repeatedly encounters signs connected to Morien: the same eyelashless eyes seen through Spirit Vision, Morien’s Eastern appearance, and his ability to project speech directly into others’ minds 36 37. Although Klein initially regards him as a potentially dangerous Mid-Sequence Beyonder, he is unsettled by an inexplicable familiarity toward him 37 39.

Morien ultimately reveals their shared connection to their original world with a fabricated “Homeland Card.” Klein answers Morien in Chinese, introducing himself as Zhou Mingrui rather than Klein Moretti 39 40. He subsequently allows Morien to enter the Tarot Club, where Morien adopts the title Mr. Tower 42 44.

As a Nighthawk, Klein becomes increasingly involved in Tingen’s supernatural incidents. He investigates the East Borough’s abnormal outbreak of philosophically obsessed lunatics, identifies the involvement of Beyonder powers through divination, and witnesses Morien publicly claim that the Tarot Club is responsible for the incident 76 78. The claim exposes Klein’s secret organization to dangerous scrutiny and leaves him furious with Morien 78.

Klein later seeks Morien’s aid when Old Neil loses control. Although distrustful of Morien’s methods, Klein prioritizes saving his colleague and invokes Mr. Fool’s apparent connection to him while asking for help 88 89. He also becomes more willing to use the Tarot Club’s resources and Morien’s insect messengers to protect his Nighthawk teammates during dangerous operations 116 117.

Appearance

Klein is a thin young man with a scholarly bearing, ordinary features, and deeply defined contours 9.

• Black hair and brown eyes 9
• Often wears modest, practical clothing, including an off-white linen shirt and apron at home 9
• His Eastern features strongly resemble Morien’s, prompting Morien’s initial interest in him 39
• As a Nighthawk, he commonly wears formal clothing and carries a cane, top hat, and equipment suited to field investigations 40 117
• As Mr. Fool, he appears seated at the head of the bronze table Above the Gray Fog, hidden behind dense mist 41 44

Personality

Klein is observant, cautious, and pragmatic. He investigates supernatural anomalies rather than ignoring them, but recognizes the danger of acting recklessly against an unknown Beyonder stronger than himself 9 37. When Christina and Morien argue at the Divination Club, he intervenes with a professional manner to defuse the situation rather than openly taking sides 37.

He carefully maintains the dignified image of Mr. Fool despite the Tarot Club’s practical limitations, including his lack of Spirituality to summon many additional members 44. Morien’s teasing repeatedly undermines this composure, particularly when he asks Klein to perform his grand introduction or makes jokes at the Fool’s expense 42 46.

Klein is deeply protective of his Nighthawk comrades. He immediately treats Old Neil’s illness as a possible loss-of-control emergency, shields Leonard when Morien approaches him during the East Borough incident, and becomes enraged when Madam Sharon nearly kills Kenley 78 88 117. Even when frightened or outmatched, he favors careful preparation, cooperation, and survival over reckless heroics 78 116 117.

He is also increasingly resourceful and willing to use unconventional support when necessary. He conceals his connection to Morien and the Wandering Star Borers from the Nighthawks, fabricates plausible intelligence to justify investigating Madam Sharon, and arranges for the Borers to intervene only if the operation becomes critical 116 117.

• Can use objects that a target carried for a long time as divination links.

Above the Gray Fog

• Perceives crimson stars linked to Tarot Club members or prayers 9 41.

Sealed Artifacts and External Support

Klein supplements his own abilities with artifacts and the Tarot Club’s resources.

• Rents the Sealed Artifact Creeping Hunger from Morien during the operation against Madam Sharon, allowing him to use abilities such as Mental Piercing, holy light, dragon-like physical enhancement, and Dragon Might 117.
• Carries a Wandering Star Borer during the operation against Sharon, following Morien’s advice that it could save the Nighthawks if the situation became critical 116 117.
• Relies on the Wandering Star Borers’ Gates, healing, and temporary “Operating Room” domain to save Kenley after Sharon’s mirror curse destroys his organs 117.

Tarot Club

Klein created the Tarot Club and maintains its structure as Mr. Fool 9 44.

• Sits at the head of the bronze table Above the Gray Fog during gatherings 41 44.
• Assigns Tarot-based codenames and schedules meetings 42.
• Introduced Morien as Mr. Tower to Audrey Hall and Alger Wilson 44.
• Coordinates with Morien beforehand so that Morien’s identity as the “great Royal Insect” supports the Club’s mystique 44.
• Acts as an intermediary for transactions when Morien sells Tarot Club members potion formulas, including relaying anonymous bank-account information to Audrey 46.
• Recruits Derrick Berg, Mr. Sun, from the Forsaken Land of the Gods and later accepts Leonard Mitchell as Mr. Star 76 86 114.
• Uses the sacrifice-and-bestowal ritual to enable future exchanges between Derrick and the outside world 115.
• Allows Morien to provide the Club with potion formulas, obscure Beyonder knowledge, the Wandering Star Borer messenger service, and access to the supposed Blasphemy Slate 45 86 87.
• Recognizes that Morien’s “2.5th Blasphemy Slate” is largely a prank: its apparent writing consists only of blurred patterns, though the other members remain awed by it 86 87.
• Faces unwanted public attention after Morien forces Leonard to publicize the Tarot Club and a newspaper attributes the deaths of Aurora Order members to the organization 85 86.

Relationships

• Morien Mo / Mr. Tower — Fellow transmigrator who identifies Klein through their shared homeland. Klein is wary of Morien’s power, cruelty, and eccentricity, but admits him to the Tarot Club and gradually develops an informal familiarity with him 39 40 42 44. Klein increasingly relies on Morien’s information and assistance during crises, including Old Neil’s loss of control and the investigation of Madam Sharon, while remaining frustrated by Morien’s reckless attempts to build the Tarot Club’s reputation 78 89 116.
• Audrey Hall / Justice — Tarot Club member. Klein values her recruitment suggestions but postpones expanding the Club because of his limited Spirituality 44. He later oversees her exchanges with Morien for the Telepathist and Psychiatrist formulas and recognizes her growing confidence in the Club 86.
• Alger Wilson / Hanged Man — Tarot Club member whose information inadvertently helps Morien trace the Club to Klein. Klein privately blames Alger for exposing the organization’s existence 40 44. Alger’s intelligence and preparations later help the Club defeat Trissy, though Klein is troubled by Morien’s decision to keep the pirate alive for experiments 111 114.
• Derrick Berg / Mr. Sun — A Tarot Club member from the City of Silver in the Forsaken Land of the Gods. Klein offers to use sacrifice and bestowal rituals to transfer materials for Derrick, potentially reconnecting the isolated City of Silver with the outside world 86 115.
• Leonard Mitchell / Mr. Star — Klein’s Nighthawk colleague and later Tarot Club member. Klein protects Leonard during Morien’s confrontation with the Nighthawks, recruits him to counterbalance Pallez Zoroast’s influence, and conceals that he himself is Mr. Fool 78 114 115.
• Pallez Zoroast — The Marauder Angel parasitizing Leonard. Klein recognizes that Pallez could be a severe threat if he learns of Sefirah Castle, so he filters the Angel out when bringing Leonard Above the Gray Fog and uses Leonard’s Tarot Club membership as deterrence 114 115 116.
• Dunn Smith — Klein’s captain in the Nighthawks. Klein trusts Dunn’s leadership during Old Neil’s emergency and the raid on Madam Sharon, while Dunn increasingly accepts Klein’s judgment and intelligence 88 89 116 117.
• Old Neil — Klein’s mysticism teacher and Nighthawk colleague. Klein recognizes his imminent loss of control and urgently seeks Morien’s help to save him rather than allowing him to be destroyed 88 89.
• Kenley — Nighthawk teammate. Klein fights alongside Kenley against Madam Sharon and is enraged by Sharon’s near-fatal curse, ultimately relying on the Wandering Star Borers to preserve Kenley’s life 117.
• Christina — Divination Club client seeking Lanevus. Klein mediates when Morien confronts her over her treatment of Megose 37.
• Megose — Client connected to Lanevus. Klein considers using her child as a future divination link, unaware at first of the danger implied by her pregnancy 37 38.
• Qiu Si — Morien’s insect offspring. Klein jokingly accepts Morien’s claim that she is his “grandniece,” while remaining uneasy about Morien’s literal insect family 41 43.
• Wandering Star Borer — One of Morien’s intelligent insect messengers. Klein maintains a cordial relationship with the creature through adventure stories and relies on its emergency support during the operation against Madam Sharon 87 116 117.

Story Role / Major Arcs

Morien’s Potion Advancement

Klein notices Morien’s newly active crimson star and remotely witnesses his consumption of the Mystery Pryer potion. This establishes Klein as both an observer of Morien’s advancement and an object of Morien’s growing interest 9.

Divination Club Encounter

Klein meets Morien in person after noticing the recurring eyelashless eyes through Spirit Vision. Morien’s projected speech, concealment ability, and apparent knowledge make Klein suspect he is a dangerous unaffiliated Beyonder 36 37.

Recognition as Fellow Transmigrators

Morien leads Klein into a private reading, plants the Homeland Card in a tarot deck, and confirms their shared connection to China. Klein responds by giving his true name, Zhou Mingrui 39 40.

Recruitment of Mr. Tower

Klein accepts Morien into the Tarot Club, lets him select the reversed Tower as his codename, and later formally introduces him to Justice and Hanged Man as Mr. Tower 42 44.

East Borough Pollution

Klein investigates a series of mentally deranged East Borough residents whose philosophical fixations, physical mutations, and criminal backgrounds indicate a supernatural cause. He and Leonard trace the case toward Enmat Harbor, only for Morien to involve himself and theatrically identify the Tarot Club as responsible for the incident 76 78.

Conflict with the Aurora Order

Klein and Leonard witness Morien’s escalating battle against Mr. Z and Botis. Recognizing that direct intervention against such powerful opponents would be suicidal, they hide and observe Morien’s Domain Expansion, Dream of a Mayfly, and the eventual defeat of the Aurora Order combatants 78 82 84 85.

Old Neil’s Loss of Control

When Old Neil becomes a monstrous, corrupted being, Klein immediately alerts Dunn and seeks Morien’s assistance through the Gray Fog. Klein supports the rescue effort by appealing to Morien’s connection with Mr. Fool, allowing Morien and the Nighthawks to reconstruct Old Neil’s body and gather his scattered spirit 88 89.

Expansion of the Tarot Club

Klein expands the Tarot Club by bringing in Derrick as Mr. Sun and Leonard as Mr. Star. He uses the Club’s authority to deter Pallez, develops a sacrifice-and-bestowal method for exchanging materials, and begins connecting the isolated City of Silver with the outside world 86 114 115.

Hunting the Demoness

After Morien identifies Madam Sharon as a Sequence 6 Demoness of Pleasure, Klein organizes a Nighthawk operation with Dunn and Kenley. Although Sharon disrupts their original plan with seduction, mirror substitution, curses, and spiderwebs, Klein’s Clown abilities, Creeping Hunger, Dunn’s support, and the Wandering Star Borers allow the team to kill her and save Kenley 116 117.
