Arc 24Kallen’s Final Sacrifice
As Otto secretly manipulates events to pursue his goal of reviving Kallen, she flees Schicksal and finds refuge with Yae Sakura. When the Erosion Herrscher takes control of Sakura, Kallen seals it at the cost of her life and accepts execution, leaving Sakura alive.
- Kallen fought Schicksal’s abuses as a masked thief, while Otto secretly guided her operations and made himself bear the blame.
- After Kallen uncovered Schicksal’s human experiments, Otto manipulated her arrest and Eleanor Schariac’s death to drive her into open conflict with Schicksal.
- Otto bargained with Void Archives for its knowledge and technology, offering to build it a vessel in exchange for its freedom.
- Wounded while fleeing Schicksal with the Black Box, Kallen reached the Far East, where Yae Sakura found her and brought her to Yae Shrine.
- As Kallen recovered, she and Yae Sakura grew close, but the Black Box preyed on Sakura’s grief over Yae Rin’s sacrifice and drove her to avenge Rin.
- The Erosion Herrscher transformed Sakura into Hiyumaru, and Kallen confronted her after she massacred the villagers.
- Kallen used Oath of Judah to restrain Sakura, burned her Life Force to seal the Herrscher’s power, and surrendered to Schicksal after securing a promise that Sakura would be spared.
- Kallen accepted Schicksal’s death sentence and silently urged Sakura to live well before the Light Screen went dark.
