Arc 27Otto’s Final Gamble
Otto sacrificed souls, allies, and civilization to reach the Imaginary Tree and rewrite the World Line so Kallen would never die. He made Kiana the final person who could free him from the Tree, while keeping a plan to regress civilization if she failed.
- Otto used Kiana’s destruction of the Theater to seize the Thousand-Person Consciousness Network, then drew the Will of Honkai’s attention and offered humanity’s accumulated souls in exchange for Kallen’s return.
- Otto used Durandal as an anchor to reach the Imaginary Tree, concealed his plan from her, and left Theresa in charge of Schicksal while preparing the world to fear Honkai.
- Otto lured Kiana and her companions to Kolosten, where trials strengthened them and revealed Durandal as the real Kiana Kaslana, while Bronya and Fu Hua were also drawn into his design.
- Otto dismantled Kolosten into a ritual pillar, using Kiana and Durandal’s emotions to reach the Tree and claim the Binding Authority, which stopped their attacks.
- Otto reshaped reality and climbed to a temple above the clouds, where the Imaginary Tree ordered him to destroy civilization, and he relied on Kiana to sever its control.
- Otto blamed humanity for Kallen’s death while suppressing his own responsibility, then urged Kiana to use her power against him so she could cut his connection to the Tree.
- Otto revealed that he would regress civilization by five hundred years if Kiana failed, and Tang San proposed that Kiana make him consider whether Kallen would accept a resurrection bought with everyone’s lives.
