Background / History

As a child, Otto was deeply affected by Kallen Kaslana and her father Francis. Kallen’s request that he join her in saving the world became the foundation of his original ideals, while Francis’s death shattered Otto’s belief in an invincible protector. 371 425

Otto and Kallen later grew apart over Destiny’s corruption and the means of saving the world. Otto avoided confronting the political rot within Destiny, prioritizing staying beside Kallen over understanding her convictions. In his desperation to save her, he threatened his sister Lisa and released captive Honkai Beasts—actions that pushed Kallen toward death. 426

After Kallen’s death, Otto rose to unify Destiny, ending the conflict involving Lisa Schariac and Marcel Apocalypse. Though celebrated as a hero who inherited Kallen’s legacy, he considered himself a failure who had merely followed in her footsteps. 409 410

For over five centuries, Otto pursued a method to restore Kallen. His partnership with Void Archives gave him access to Previous Era knowledge, but also left him bound to the Divine Key for more than 500 years. 374 427

Appearance

Otto is usually depicted as a refined blond man with a composed, aristocratic bearing. His appearance is highly variable because his Honkai Steel bodies can imitate different ages, genders, and identities.

• Golden hair, often paired with white clothing or formal bishop attire. 9 191 346
• Wears purple bishop robes when acting openly as Destiny’s leader. 346
• Can assume child-like, female, or entirely different identities through Honkai Steel mimicry. 347
• His pseudo-god form manifests Imaginary wings, a halo, and later an angelic white-winged appearance. 446

Personality

Otto is calculating, eloquent, and exceptionally difficult to read. He habitually withholds information, provokes opponents into emotional reactions, and presents his plans only after they have become impossible to prevent. 28 417

His devotion to Kallen is the defining force behind his life. He is willing to discard morality, manipulate allies, cooperate with the Honkai consciousness, and even destroy the present world for a chance to alter her fate. 19 417 428

Despite his cruelty, Otto is not emotionless. He acknowledges himself as a “rational evil person,” regrets his failures, cares for Theresa and his students, and ultimately accepts death as the cost of achieving Kallen’s future. 427 449

Story Role / Major Arcs

Second Herrscher Conflict

Otto confronts Sirin’s forces at the Tower of Babylon. He defeats the Pseudo Herrscher of Death, discovers that her core is false, and declares war on Sirin after deciding she stands in the way of Kallen’s revival. 19

He later manipulates Sirin’s memories to make her seek the Herrscher of Death’s power, using her grief over her mother as leverage. 23

Destiny’s Shadow Leader

While leading Destiny, Otto repeatedly engineers crises from behind the scenes. He revives Kiana and Honkai Beasts, launches a Honkai energy fission bomb toward Cuba, and remains indifferent to disasters that do not interfere with his own experiments. 61 100 173

Herrscher of Domination Trap

Otto manufactures a Honkai Steel host convinced that it is his failed self from 500 years earlier. The Herrscher of Domination takes the bait, allowing Otto to reclaim its core; the plan succeeds at the cost of the host’s life. 406 408

Final Plan and Sacrifice

Otto resigns as Destiny’s Archbishop, appoints Theresa as his successor, and reveals that he intends to use the Imaginary Tree to create a new branch of time in which Kallen survives. 409 417

After taking the authorities of Domination and Binding and becoming a pseudo-god, he battles Kiana and Durandal. His apparent invincibility is a deliberate setup: he needs Kiana to kill him and split history into two worlds. 429 446 447

Otto reaches the Imaginary Tree, defeats the Honkai Beast representing Kallen’s death, and creates a new future for her. He then sacrifices himself to save Kallen and the city, leaving her with a final command to live on. 450 451
