Vol. 7Otto’s Last World Line
Otto pursued Kallen’s resurrection across decades, using Kiana and the Imaginary Tree to rewrite history. He vanished after creating a world where Kallen lived without Honkai, though her execution remained fixed and the timelines left a lasting crack in history.
- Otto rebuilt Schicksal and traveled to Mount Taixu with Kallen’s coffin, where he uncovered Fu Hua’s staged ascension and awakened her from her seal.
- Otto revealed that Fu Hua had sealed away memories of her disciples and precious experiences, then left Mount Taixu with her as he pursued his plan to revive Kallen.
- Fu Hua rejected Su Mei and left Mount Taixu, while Otto later used Li Sushang and Kiana in his plans to find a World Line where Kallen lived.
- Otto shaped Kiana into the Herrscher of Flamescion and watched as she entered the Theater of Domination.
- Otto sacrificed souls and used Durandal as an anchor to reach the Imaginary Tree, then lured Kiana and her companions to Kolosten to carry out his plan.
- Otto revealed that he would regress civilization if Kiana failed to stop him, and Tang San urged Kiana to make him consider whether Kallen would accept such a resurrection.
- Kiana and Durandal fought Otto on the Ice Field, and Kiana’s strike let him sever his ties to the current World Line.
- Otto gave his existence to the Tree to create a world where Kallen lived without Honkai, but her execution remained fixed and the timelines left a lasting crack in history.
