Background / History

Otto serves as one of St. Freya Academy's founders and its Disciplinary Department director, while holding the greater authority of Schicksal's Grand Bishop. He funds much of St. Freya's development and maintains influence over its staff, facilities, and Valkyrie training programs. 5 21 247

After Li Pu's unusual actions draw his attention, Otto identifies him as a possible candidate for creating a Herrscher and orders Rita to monitor him. He becomes particularly interested when Li Pu's cosplay knowledge accurately identifies aspects of King Arthur's weapons that are classified even to Otto. 5 10

Otto activates the sealed Trace Origins, Soul Recall technology on Li Pu under the cover of an immersive-learning test. The apparatus is intended to trace past-life memories and personalities; Otto initially accepts the risk to Li Pu because other potential subjects exist. 11 The experiment awakens unexpected reincarnation-related identities, including Cecilia and King Arthur, prompting Otto to seal the machine rather than risk further uncontrollable results. 21

His investigation of Li Pu's transformations leads Schicksal to conclude that Li Pu can manifest past selves through soul awakening, gaining their distinct abilities and combat skills. 220 Otto later tests Li Pu's connection to Kallen by allowing him access to Kallen's weapon, Colorless Serenade. 190

Personality

Otto presents himself with polished courtesy and a controlled smile, but routinely conceals his true intentions. He is calculating, patient, and willing to manipulate information, personnel, and crises to produce favorable conditions for Schicksal or his research. 27 248 303

His overriding personal fixation is Kallen. Otto prioritizes her safety, return, and reincarnations over other concerns, including the lives of Yae Village's residents. He is open about this hierarchy when pressed, stating that no one surpasses Kallen in his heart. 190 191

This fixation can undermine his usual composure. He becomes irrational over Kallen-related photographs, argues anonymously over Kallen Fantasy pairings, and reacts strongly to criticism of his relationship with her. 145 174 Nonetheless, he remains capable of pragmatic political calculations when Schicksal's interests are involved. 313 314

Story Role / Major Arcs

St. Freya Soul-Awakening Experiments

Otto recruits Li Pu's potential into his broader Herrscher plans, monitors him through Rita, and uses the sealed soul-recall device to awaken past-life memories. The resulting overlap of King Arthur and Cecilia reincarnation signals leaves Otto intrigued but unable to fully control the outcome. 5 11 21

Kallen Fantasy and the Kallen Return Project

Otto creates and promotes Kallen Fantasy as more than entertainment: it serves as a medium for spreading hidden mechanisms and collecting Kallen Soul Fragments. He becomes personally involved in defending the game online, even escalating a dispute with Li Pu into account deletions and a planned Blade of Unending intervention. 174 175 207 268

Yae Village Investigation

Otto enters Yae Village intending to return Kallen to Schicksal and clear her name by retrieving the Demon in the Box. A massive Honkai Beast attack, the weakness of Yae Sakura's seal, and anomalies surrounding the box convince him that the disaster was arranged rather than random, leading him to remain and investigate. 187 190

Artificial Honkai and Herrscher Planning

During the artificial Honkai crisis, Otto recognizes the potential for a Herrscher's birth and chooses to use the event as a test for his goal of producing Herrschers who retain human consciousness. Although he denies causing the crisis, he intentionally allows events to develop while preparing Schicksal to secure the resulting Herrscher. 285 298 303

Xuanyuan Sword Interest

After sensing a nonstandard power within the Xuanyuan Sword, Otto sees the weapon as a possible route toward breaking the cycle of fighting Honkai with Honkai. He remains reluctant to pursue it without clear political and organizational benefits for Schicksal. 313 314
