Unfortunately, without Otto's consciousness granting permission, Void Archive's plan to replace Otto was declared a failure.
Void Archive was also put on Otto's guard list, and he would never trust its words again.
With its mask exposed, Void Archive no longer bothered to hide anything. It openly declared that it had lost faith in the Apocalypse family and wanted to carry out the task of advancing civilization itself!
At that point, Otto began his long road of scheming against Void Archive. From treating each other with respect to undermining each other at every turn—such was the story of Otto and Void Archive.
Theresa skipped over much of Void Archive's later story, because Welt himself had personally experienced those events.
Theresa then roughly recounted the tragic story of Otto and Kallen. As they grew up, their feelings for one another rapidly deepened. However, Kallen discovered Otto's human experiments and became utterly disappointed in him. Carrying a box of Soul Steel, she fled to the Far East, where she met the most important woman in her life.
That woman was Yae Sakura. Kallen and Yae Sakura hit it off at first sight. The Kaslana bloodline's urge for intimacy kicked in, and Kallen fell for Yae Sakura. Otto also gained a new title: the Number One Cuckold~
The story afterward was that Kallen spent a brief yet wonderful time in Yae Village. Unfortunately, the box of Soul Steel she had brought leaked Destruction Energy and released the Herrscher of Erosion from the Previous Civilization—Himeko.
Yae Sakura was then influenced by Destruction Energy, compounded by her own experiences. Yae Village had a goddamn custom: whenever the heavens withheld rain, they had to sacrifice a young girl.
Yae Sakura's younger sister, Yae Rin, was chosen with the villagers and Yae Sakura's father fanning the flames.
