Background / History

Five-Hundred-Year Objective

Otto retained the same appearance for centuries and built an enormous foundation through five hundred years as Schicksal's Archbishop. His ultimate objective was to reach the Imaginary Tree and save Kallen, after which he intended to remove himself from her life rather than claim a place in it. 38 104 306 310

He regarded his connection with Kallen as the defining force of his life. Her memory influenced his treatment of Yae Sakura, whom he saw as another person capable of remembering Kallen. 97 99 104

Artificial Herrscher and Sirin Projects

Otto personally oversaw Delta's transformation into the first artificial Herrscher, considering it both a breakthrough and a trial run for the Sirin Project. He ordered Durandal to secure the Oceania branch and Rita to eliminate the abusive branch leader and his associates. 44

When Delta lost control, Otto ordered Durandal to force her back into position and used Wendy as leverage to provoke Delta into regaining consciousness. 46 He later deployed Delta as an S-rank Valkyrie and recorded her combat data for future research. 49 54

His surveillance of K423 focused on cultivating a controllable Herrscher of the Void through her experiences and emotional bonds, provided she survived. 66 118 153

Divine Key Operations

Otto possessed Keys of Domination and agreed to provide one to Fu Hua, his long-time associate, while discreetly ordering Amber to investigate Fu Hua's prospective disciple. 38

He pursued the Second Divine Key, Chikai Ichijo, as an indispensable component of his final plan. After securing it, he focused on unlocking its zero-rated power through an authorization beacon. 87 91 198 261

Yae Sakura's Recruitment

After identifying Yae Sakura as someone deeply connected to Kallen, Otto revealed his identity and brought her under Schicksal's protection. He arranged her education with Amber, daily-life instruction with Rita, and combat training with Durandal. 97 100 104

Although he repeatedly warned Yae Sakura not to trust him too much, Otto grew protective of her and hesitated to involve her in his plans. 104 He eventually persuaded her to become a Valkyrie, mentored her in leadership and politics, and considered her a potential successor. 153 253 274 281

Final Plan and Death

With a team of scientists preparing a phantom reconstruction of a town from five hundred years ago, Otto proceeded with his plan to seize a Herrscher position through the Gem of Pestilence. 312

As a pseudo-god, Otto fought several powerful opponents while hoping they would defeat him rather than force him to use his own power to alter five hundred years of history. 313 Anqi used the Void Authority to push him out of the world; Otto accepted the outcome with gratitude. 314

Near death, Otto recognized Yae Sakura's deception, accepted it without resentment, and chose to fulfill his promises before meeting Kallen. He left Theresa a final message and entrusted Yae Sakura with his remaining task. 315

Appearance

Otto's face is described as unchanged for hundreds of years, with a handsome appearance usually accompanied by a composed or pleasant smile. 38 97

• Maintains a youthful, unchanged face despite his centuries-long life. 38
• Frequently presents a warm, courteous smile even while issuing ruthless orders. 44 54
• Can operate through Soul Steel bodies; one such body impersonated Catherine before revealing Otto's own face. 90
• Possesses multiple backup lives, making direct threats to his body an unreliable measure of danger. 43

Personality

Otto is an exceptionally patient planner who treats warfare, politics, and even interpersonal conflict as parts of a larger script. He gathers intelligence extensively, anticipates decoys and countermeasures, and values combat data, Divine Keys, Herrscher cores, and promising individuals according to their usefulness to his objectives. 53 54 131 132 254

His calm politeness conceals a willingness to manipulate others. He used Wendy to control Delta, planned to eliminate Welt to remove a strategic obstacle, and cultivated K423's emotional development as part of the Sirin Project. 46 53 153

Despite this ruthlessness, Otto sincerely admires selfless people and is deeply affected by Kallen's legacy. He shows unusual gentleness toward Yae Sakura, respects Fu Hua as an old friend, and ultimately prioritizes leaving behind a world worthy of Kallen, Yae Sakura, Theresa, and Durandal. 104 127 286 310
