Three men were flying from another universe back to their own. They were on a quest to find universes outside the dominion of the higher echelon. Everything was going as planed, They had fun in the process and were about to travel back to their '13th universe'. That's when they kinda got sidetracked.
Just as they reached the 'void between' so Aro can warp into the 13th univese he fell asleep, yet still warped. They kept flying towards their destination, unaware they were not where they thought they were.
Aro woke up on the approach to their Home planet, but something was off... As the group came from the dark side of the planet, the surface had too many bright spots, like a million lights tightly packed in one place. That raised all sorts of warning bells in Aro's mind. That ment advanced civilization.
Yet, he still went towards Zipangu, as the group was about to visit Lady Nozomi's temple before deciding if another scouting was necessary.
Aro Landed the group in a concealed spot near a park in the Capital. or what they all thought was the Zipangese capital, but the scene was mind boggling. There was no way this was Zipangu!
