"According to what I learned, Chaos is infinitely vast and filled with countless realms, and Gehenna is only a single drop in this vast ocean of realms. Therefore, it's reasonable to think that even Gehenna would have a few neighboring realms."

"If this world is truly that attractive to the denizens of Chaos, what do you all think would happen once the neighboring realms discovered there was only a single dimensional crack in Gehenna?" Vaan asked.

"Considering even one of the Storm Calamity Witch's close retainer, a Rank 6 being, chose to enter the cycle of reincarnation to be reborn outside of Chaos, there's no doubt that these neighboring realms would invade Gehenna," Kemun stated.
