After the end of the negotiations, Zeta did not immediately went to any of the nations for a visit. Instead she teleportated away and went to where Elena was. She was really excited to show Elena the mecha dragon and the humanoid golem. From what she knew of Elena's personality, Zeta was sure that Elena was going to like them.
...
After she teleportated away, Zeta found herself in the realm of the will of the world. In her excitement, she had ended up using her true strength as a Chaosborn to do this teleportation and had bypassed all the defenses that the realm of the Will of the world had against teleportation.
This immediately frightened the will of the world as only someone extremely powerful was capable of doing something like this. So she immediately went behind Elena to hide. Even though Miyamura was also quite powerful, as the world savior, Elena gave off a safer feeling to Oss.
