The Origin Oath Between The Higher Existences

Weiss knew that there were game items that could be useful in the late game of Cozy Vacation Life on the luxury cruise ship. However, since Ayame decided not to go late game, then there wasn't any point in obtaining those game items this early.

Ayame was also aware of that. However, she wanted to secure the authorities.

Although Ayame knew that her brother could secure their win, Ayame still wanted to secure the authorities first.

After all, if an otherworld invasion were to start again, they would be forced out of the game by the Game AI. If that happened when they were in the late game of Cozy Vacation Life, then they wouldn't have the authorities in their possession since they haven't brought it back to the real world yet.

If that were to happen, then Ayame would rather want to obtain the authorities as soon as possible to improve her and her team's power.
