Background / History

Otto ruled Schicksal as an absolute dictator: branch leaders understood that losing his favor or usefulness could lead to their disappearance. Despite this tyranny, he maintained Schicksal as a central force against the Honkai and developed anti-Honkai weapons, Valkyrie Armor, and technology derived from the Previous Era. 38 565

His defining objective was reviving his late fiancée, Kallen Kaslana. Otto pursued this goal for roughly five centuries, accepting information from the Honkai God while continually seeking alternatives such as the Second Divine Key, the Gem of Serenity, Ophion resurrection powers, and Fueki Sou's Ritual of Rebirth. 362 386 432

Otto proposed Schicksal's artificial Herrscher project, which fused Valkyries with Herrscher Cores. The program frequently killed its subjects, but Otto considered its potential to create controllable Herrscher-level weapons worth the cost. 64 540

Personality

Otto is composed, charismatic, and exceptionally calculating. He can present himself as a gentle elder or a reasonable leader while arranging coercion, surveillance, human experimentation, and assassination behind the scenes. He uses information as leverage, tailoring his rhetoric to the target's fears, loyalties, or personal history. 61 91 161

His attachment to Kallen overrides virtually every other principle. Otto is willing to nurture the Honkai, endanger civilians, sacrifice subordinates, and destabilize the world if doing so advances her resurrection. Even his apparent remorse after Sky Dome City's destruction does not stop him from continuing his plan. 540 556 725

He is not primarily a frontline fighter and recognizes the value of patience, preparation, and contingencies. However, his confidence in his schemes repeatedly causes him to underestimate opponents such as Gu Yu, Fu Hua, and the Outworlders. 62 248 484

Abilities & Skills

Strategic Intelligence and Information Control

Otto operates Schicksal through surveillance, informants, planted devices, and political pressure.

• Monitored the Hyperion incident through Rita's surveillance equipment and rapidly identified Gu Yu's spatial ability as a potential clue to Sirin's Core. 45
• Used Rita as a deliberate distraction while pursuing separate operations against Gu Yu. 91
• Planted surveillance devices across Schicksal branches and installed a listening device on Rita to monitor both her and the Valkyrie dormitory. 609 661
• Identified Gu Yu's access to advanced intelligence and suspected Durandal of being an information leak. 161 175

Soul Steel Bodies and Soul Backups

Otto transfers himself between replacement Soul Steel bodies, allowing him to survive destruction that would otherwise be fatal.

• Soul Steel grants strong resistance to ordinary physical damage and can suppress pain, though specialized attacks can damage or dismantle it. 62 64
• Maintained numerous backup bodies around the world and stored soul backups in supercomputers. 487 578 738
• His survivability was finally neutralized when Higanbana destroyed his spare bodies and supercomputers after accessing his memories. 738
• The system did not prevent him from being repeatedly incapacitated, including by Fu Hua, Kevin, Gu Yu, and Outworlder energy. 248 484 614

Divine Key Mimicry

Using Void Storage, Otto can reproduce Divine Keys and their core functions, though the mimics are weaker than the originals.

• Mimicry Oath of Judah — Creates Soul Steel chains that bind targets, nullify Honkai Energy, weaken other energies, and track movement. 62
• Divine Prayer Barrier — Deploys a powerful energy-suppressing barrier; it can heavily strain Otto and was ineffective against enemies able to enter the Mirror World. 45 63 248
• Mimicry Heavenly Fire Holy Judgment — Used as a high-output attack against Gu Yu. 63
• Mimicry Feather Dust / Utsu-semi — Alters memories or plants suggestions; Otto used it to conceal implanted bombs and make targets overlook abnormalities. 136 717

Scientific Research

Otto is an accomplished researcher whose work shapes Schicksal's military and experimental capacity.

• Developed or advanced Valkyrie Armor, Divine Machine weaponry, anti-Honkai armaments, and Previous Era technology. 565
• Proposed the artificial Herrscher project and used Core Fusion Rate to assess whether subjects could survive contact with Herrscher Cores. 64
• Constructed an advanced medical pod capable of restoring Fu Hua's body and memories—an outcome that turned her into an enemy. 484
• Recreated a city-scale Honkai Energy suppression device using data related to the Herrscher of Binding. 716

Equipment / Weapons / Items

• Void Storage — Divine Key used to mimic other Divine Keys and access stored technology. 61 319
• Mimicry Oath of Judah — Binding and energy-suppression weapon. 62
• Mimicry Feather Dust / Utsu-semi — Memory manipulation and suggestion tool. 136 717
• Soul Steel bodies — Replaceable vessels for Otto's consciousness. 487 578
• Honkai Energy Fission Bombs — Weapons used as both battlefield assets and coercive deterrents; Otto used one in his attempt to corner Gu Yu in Sky Dome City. 661 719
• Thousand Worlds / Second Divine Key — A central component of Otto's later plans and negotiations with Kevin. 310 574

Relationships

• Kallen Kaslana — Otto's late fiancée and the sole constant behind his centuries-long pursuit of resurrection. 362 432 540
• Theresa Apocalypse — His granddaughter. Otto genuinely cherishes her, but still pressures and manipulates her when his plans require it. 45 386 568
• Rita Roosevelt — His adjutant and most trusted operative, though Otto ultimately treats her as a disposable tool and uses her as bait against Gu Yu. 161 683 719
• Durandal — Schicksal's strongest Valkyrie and a highly obedient subordinate. Otto later becomes suspicious that she may be leaking information to Gu Yu. 41 175
• Fu Hua — A five-century-old friend whom Otto attempts to turn into a restored trump card; she regains her memories, recognizes his betrayal, and destroys one of his bodies. 362 484
• Gu Yu — A dangerous adversary Otto initially tries to recruit, drug, study, manipulate, and eventually eliminate. Their conflict becomes the main obstacle to Otto's plans. 61 161 661
• Kiana / K423 — A key subject in Otto's Sirin Project. Otto intends to use her connections, Herrscher powers, and additional cores to create a controllable Herrscher of the Void. 41 175 484
• Kevin Kaslana — A temporary ally and rival negotiator. They trade information and resources while each expects betrayal from the other. 574 609 614
• Fueki Sou — A prospective partner in resurrection research. Both attempt to exploit the other's desire to revive a loved one. 432 440

Story Role / Major Arcs

Hyperion Incident and Gu Yu's Arrival

Otto observes the Hyperion crisis remotely, orders Durandal to secretly retrieve Siegfried if he falls, and pressures Theresa to sacrifice the stranger if necessary to protect the ship and its crew. 45

After Gu Yu exposes knowledge of Schicksal's human experimentation, Otto travels to St. Freya Academy. He attempts to drug Gu Yu, exploit his fabricated history, and seize his Stigmata for research. 51 61

First Defeats by Gu Yu

Otto personally fights Gu Yu using Mimicry Oath of Judah and Divine Prayer Barrier. Gu Yu counters Otto's Soul Steel body through Beethoven Damashii's matter-decomposition attacks and escapes through the Mirror World. 62 63

The battle ends with Otto severely humiliated and physically beaten by Gu Yu. Rather than immediately retaliate, Otto changes tactics and has Rita stall Gu Yu while he investigates the source of Gu Yu's intelligence. 64 161

Artificial Herrscher Schemes

Otto engineers Herrscher awakenings through Core-fusion experiments, including Wendy's transformation at the Oceania Branch. He intends to use Mimicry Feather Dust to control Wendy and Theresa, but Gu Yu's intervention disrupts the plan. 136 540

He also prepares K423 to become a Herrscher of the Void possessing multiple Herrscher Cores, intending to use the resulting power as both a weapon and a route toward Kallen's resurrection. 175 484

Divine Key and Resurrection Pursuits

Otto searches for Thousand Worlds, investigates Outworlders, and seeks the rumored resurrection powers of Ophion. His Outworlder experiment destroys the Helsheim Laboratory, severely damages his Soul Steel body, and forces him to halt the program. 248 310 352 362

He later contacts Fueki Sou over the Ritual of Rebirth, but their cooperation remains defined by deception and mutually incompatible ambitions. 432 440 489

War Against Gu Yu

As Gu Yu becomes increasingly powerful, Otto concludes that negotiation is no longer sufficient. He joins Kevin in the Gu Yu Hunt Plan, builds a city-scale suppression device, frames Gu Yu as the Thirteenth Herrscher, and implants bombs in Rita, Durandal, and Kiana. 661 716 717

Otto uses Rita and Sky Dome City as leverage, detonating the bomb inside her and threatening further devastation if Gu Yu retaliates. Gu Yu reverses time to save Rita and Theodora, removing Otto's immediate advantage. 719 725

Downfall

Theresa challenges Otto's authority while Schicksal's branches divide over his actions. Otto reveals that his death would trigger global self-destruction protocols involving Schicksal's weapon arsenal and Honkai Energy Fission Bombs. 731 736 737

Gu Yu captures Otto, learns the mechanism behind his Soul Steel immortality, and brings Higanbana to erase his backups. With Otto's contingencies neutralized, Gu Yu kills him; to keep Schicksal stable, Gu Yu assumes Otto's identity and publicly continues as the Grand Bishop. 738 740 741

Notable Quotes

“Theresa, you are my beloved granddaughter. But I hope you understand that people die in war.” 45

“My value alive is far greater than my value dead!” 740

Trivia

• He repeatedly suffers humiliating physical defeats despite his extensive preparation, including defeats by Gu Yu and Fu Hua. 64 484
• Otto's death remains unknown to most of Schicksal because Gu Yu impersonates him after killing him. 741 760
