Background and History

Childhood

Otto was born into the Apocalypse Family, one of Schicksal's three great families. Frail and chronically sick from birth, he possessed no combat talent and could not withstand Honkai Energy cleansing; his family instead prized the martial strength of his elder brothers. 541 543

His intellect manifested through invention. As a child, he built a mechanical bird capable of flight, only for his brothers to call it worthless craftsmanship, smash it to pieces, and grind the remains beneath their boots. The humiliation stripped away much of Otto's innocence and drove him toward ancient records, relics, and the underlying laws of the world. 544 545

Kallen Kaslana and the forbidden path

Kallen Kaslana was the first person to sincerely recognize Otto's intelligence, taking interest in his machines rather than scorning them. Her acceptance became the emotional center of his life. 545 549

When Kallen's father died, Otto broke into the Apocalypse sanctuary and appealed to Void Archives for a means of resurrection. He used its knowledge to mimic the Black Abyss White Flower, but the imitation lacked the true authority of life and death. Kallen rejected his attempt to violate that taboo, shattering Otto's belief that good intentions could justify his methods. 558 559

Afterward, Otto resolved to obtain knowledge and power beyond all rules, even if Kallen herself opposed him. He gained access to Schicksal's most restricted laboratory to conduct human experiments under the pretext of developing a cure for the Black Death. 561 563

Pact with Void Archives

After Kallen became wanted by Schicksal, Otto returned to Void Archives not as its keeper, but as an equal negotiator. He offered it a vessel and energy for freedom of manifestation in exchange for the complete technological legacy of the Previous Civilization. 588 590

The bargain gave Otto access to knowledge and technology that enabled his long-term rule: advanced weapons, intelligence networks, artificial bodies, and methods of evading death. 591

Rise within Schicksal

Otto secretly used Kallen's justice-driven actions against Schicksal as cover for his own plans. While Kallen acted publicly as a masked thief who aided the poor, Otto exploited her reputation to undermine Schicksal's internal factions and dismantle the institution from within. 580 582

Following Kallen's death, Otto eventually raised a coalition in her name. In 1491, he overthrew Lisa and Marcel's oppressive regime and became Schicksal's new leader, swearing to protect everything Kallen had sought to protect. 609

As Archbishop, he rebuilt Schicksal into a tightly structured organization with clear chains of authority and coordination. He processed at least three hundred memorials in eight hours while expanding research into Honkai, Previous Civilization relics, and countermeasures against global disaster. 610 611

Appearance

Otto is a handsome blond man with green or emerald eyes, usually presented in immaculate white-and-gold bishop's robes. His composed smile and refined bearing are central to his carefully cultivated image as Schicksal's compassionate savior. 418 422 639

• Blond hair and emerald-green eyes; at one point, he is described with one emerald and one golden eye. 418 612
• Frequently wears formal white bishop's vestments, often paired with a scepter or other ceremonial regalia. 418 639
• Wears glasses during negotiations and strategic discussions. 391
• Successfully disguised himself as the beautiful noblewoman Lady Green Lily to distract an entire ballroom. 581 582

Personality

Otto is defined by a single, overwhelming fixation on Kallen. He does not pursue power, status, or cruelty for their own sake; he treats all of them as tools toward giving Kallen life, happiness, or another chance to exist. This devotion becomes possessive, manipulative, and detached from Kallen's own wishes. 536 576 580

He is patient, highly rational, and willing to wait centuries for a favorable outcome. Otto consistently reframes people, relationships, institutions, and even himself as assets, costs, or pieces on a chessboard. By the end of his five-century plan, he is described as a machine sustained solely by obsession rather than an ordinary person capable of remorse or attachment. 545 638 639

His public demeanor sharply contrasts with his private conduct. As Schicksal's bishop, he is gentle, reassuring, and capable of inspiring total loyalty; behind that image, he calmly authorizes human experimentation, treats Valkyries as disposable resources, and maintains a world perpetually dependent on his protection. 639 640 642

Otto nevertheless displays rare tenderness toward individuals such as Vera, whom he teaches to read and allows to call him “Brother.” 611 612

Abilities and Skills

Genius intellect and strategic planning

Otto's greatest strength is his intellect. Despite his frail body, he can negotiate with divine artifacts, establish multi-century plans, manipulate institutions, and accurately calculate the desires and reactions of others. 541 589 592

• Turned Void Archives' desire for freedom into leverage, securing the Previous Civilization's knowledge through an “equal trade.” 590 591
• Led a smaller coalition army to defeat Lisa and Marcel through calculated deployments, feints, and battlefield command. 609
• Reorganized Schicksal's bureaucracy into an efficient top-down system. 610
• Uses carefully timed rescues, surveillance, propaganda, and staged crises to create dependence and control. 526 633 642

Scientific and technological mastery

Otto is an inventor and scientist whose work ranges from mechanical devices to Honkai-based weapons, artificial bodies, stigmata research, and Previous Civilization technology. 544 591 639

• Created mechanical devices from childhood, including a flying mechanical bird. 544
• Designed the Sixth-Generation Sacred Vestment: Confession, a healing garment intended to protect Kallen from injury. 555
• Developed Valkyrie armor, Artificial Stigmata programs, Honkai suppression technology, and biological research systems. 610 639 642
• Maintained numerous spare bodies and clones, allowing him to survive the destruction of individual vessels. 480

Manipulation and psychological warfare

Otto uses truthful statements, public benevolence, and carefully engineered suffering to make others choose the outcomes he wants. 580 640

• Framed Welt Joyce as a demon while using Schicksal propaganda and Valkyrie attacks to discredit him. 426
• Monitored Kiana through hidden nanoscale probes and treated her emotional growth as experimental data. 526 529 535
• Allowed Theresa, Bronya, and others to remain in danger to force out Kiana's humanity and power. 462 463
• Delayed his rescue of Li Sushang until she was on the verge of death, deliberately fostering her dependence on him. 632 633

Honkai and Divine Key operations

Otto can employ or exploit powerful Honkai-related artifacts and phenomena despite lacking natural combat talent. 391 441 623

• Used Fenghuang Down and Sirin as a bridge to invade the consciousness space of the Honkai Gods. 441
• Wielded a Honkai Spear while confronting Fu Hua's seven disciples at Mount Taixu. 623
• Activated Fu Hua's seal using his knowledge of ancient Previous Civilization script. 623
• Used the Thousand Realms Equalling One beacon and Mimicry: Fenghuang Down to force open a path through time. 391 542

Equipment and Items

• Void Archives — First Divine Key and living library containing most of the Previous Civilization's knowledge; Otto negotiated a partnership with it and used it as a source of technology, records, and control over Schicksal. 391 588 591
• Thousand Realms Equalling One beacon — Acquired from Kevin in exchange for all of Schicksal; later used in Otto's final time-related plan. 391 542
• Fenghuang Down — Divine Key capable of restoring Fu Hua to her peak temporarily at the cost of memories; Otto also possesses a Mimicry version. 439 542
• Heavenly Fire Holy Judgment — Weapon used to kill Eleanor when she transformed into a Collapse Beast. 586
• Honkai Spear — Weapon used while blocking the seven disciples from interfering with Fu Hua's awakening. 623
• Silver cross — Kallen's relic, carried by Otto during his oath to protect her world. 609
• Silver pocket watch — Engraved with Kallen's name and kept by Otto during his century-long search for a method to revive her. 613

Relationships

• Kallen Kaslana — Otto's nominal fiancée, first source of validation, and the sole purpose behind his five-hundred-year plan. His love is unrequited and increasingly treats her happiness, memory, and resurrection as goals to be achieved regardless of her wishes. 545 601 638
• Void Archives — Divine Key, knowledge source, and negotiated partner. Otto outmaneuvered it by offering freedom and manifestation in exchange for its technological legacy. 589 590 591
• Fu Hua — Old friend and frequent target of Otto's schemes. He used her agreements and body for his plans, yet later sought to awaken her sealed true self and arranged terms under which she could set down her fifty-thousand-year burden. 466 480 623 635
• Kiana Kaslana / K423 — Otto's engineered vessel, created from the real Kiana's genes and Sirin's core and genes. He monitored and pressured her throughout her life to study and refine her development. 424 529 535
• Vera Otto — A girl Otto and Kallen rescued, who came to call him “Brother” and later pledged absolute loyalty as his sword and guard captain. 612 613
• Welt Joyce — Hero and First Herrscher who opposed Otto. Otto framed him as a demon, attacked him through Schicksal, and ultimately betrayed him. 426 433
• Theresa and Bronya — Allies Otto knowingly left in danger, using their suffering as a catalyst for Kiana's awakening. 462 463
• Eleanor — Otto's sister, whose loyalty he repaid by killing her after her Collapse Beast transformation and harvesting her remains as experimental material. 586
• Li Sushang — Otto saved her from a staged crisis, then exploited her need to find Chi Yuan to guide him toward his own objective. 633
• Kevin — Exchanged the complete authority of Schicksal for Kevin's Thousand Realms Equalling One beacon. 391
