Arc 29Otto’s Final Sacrifice
Otto gave up his existence to alter the past and save Kallen, creating a new world line where she survived without remembering him. After history was corrected, his remaining power repaired the cracks in spacetime.
- Tang San, Gu Yuena, and Huo Yuhao explained that the Imaginary Tree used Otto’s obsession with Kallen to open a new world line, then erased him from cause and effect.
- Otto accepted that saving Kallen meant he could not survive, fought the discarded versions of himself, and burned his existence to reach the Imaginary Tree’s power.
- Otto battled the Imaginary Tree’s phantoms and the beast formed from his sins, then used the Divine Keys and Void Archives to clear his path toward the Tree.
- As Kallen died at the execution ground, Otto remembered their youth and pressed on, using his final strength to rewrite her fate.
- The Imaginary Tree healed Kallen and created a branch where she survived, while erasing Otto’s memories, records, and existence from history.
- Otto’s sacrifice left a faint hidden record in the Tree, and the onlookers learned that Kallen would never know who had saved her.
- Otto’s golden meteor reached Kallen’s execution and changed history so the Collapse Beast’s claw missed her, allowing Kallen to kill it and leave with the little girl.
- Spacetime cracked after the correction, and Otto’s remaining golden power spread through the cracks to repair them.
